The future of music creation

When I was a student, I saw people around me that could play musical instruments and since I couldn’t, I felt a bit inadequate, so I went out and bought a £13 guitar and taught myself to play. Later, I bought a keyboard and learned to play that too. I’ve never been much good at either, and can’t read music, but  if I know a tune, I can usually play it by ear and sometimes I compose, though I never record any of my compositions. Music is highly rewarding, whether listening or creating. I play well enough for my enjoyment and there are plenty of others who can play far better to entertain audiences.

Like almost everyone, most of the music I listen to is created by others and today, you can access music by a wide range of means. It does seem to me though that the music industry is stuck in the 20th century. Even concerts seem primitive compared to what is possible. So have streaming and download services. For some reason, new technology seems mostly to have escaped its attention, apart from a few geeks. There are a few innovative musicians and bands out there but they represent a tiny fraction of the music industry. Mainstream music is decades out of date.

Starting with the instruments themselves, even electronic instruments produce sound that appears to come from a single location. An electronic violin or guitar is just an electronic version of a violin or guitar, the sound all appears to come from a single point all the way through. It doesn’t  throw sound all over the place or use a wide range of dynamic effects to embrace the audience in surround sound effects. Why not? Why can’t a musician or a technician make the music meander around the listener, creating additional emotional content by getting up close, whispering right into an ear, like a violinist picking out an individual woman in a bar and serenading her? High quality surround sound systems have been in home cinemas for yonks. They are certainly easy to arrange in a high budget concert. Audio shouldn’t stop with stereo. It is surprising just how little use current music makes of existing surround sound capability. It is as if they think everyone only ever listens on headphones.

Of course, there is no rule that electronic instruments have to be just electronic derivatives of traditional ones, and to be fair, many sounds and effects on keyboards and electric guitars do go a lot further than just emulating traditional variants. But there still seems to be very little innovation in new kinds of instrument to explore dynamic audio effects, especially any that make full use of the space around the musician and audience. With the gesture recognition already available even on an Xbox or PS3, surely we should have a much more imaginative range of potential instruments, where you can make precise gestures, wave or throw your arms, squeeze your hands, make an emotional facial expression or delicately pinch, bend or slide fingers to create effects. Even multi-touch on phones or pads should have made a far bigger impact by now.

(As an aside, ever since I was a child, I have thought that there must be a visual equivalent to music. I don’t know what it is, and probably never will, but surely, there must be visual patterns or effects that can generate an equivalent emotional response to music. I feel sure that one day someone will discover how to generate them and the field will develop.)

The human body is a good instrument itself. Most people can sing to a point or at least hum or whistle a tune even if they can’t play an instrument. A musical instrument is really just an unnecessary interface between your brain, which knows what sound you want to make, and an audio production mechanism. Up until the late 20th century, the instrument made the sound, today, outside of a live concert at least,  it is very usually a computer with a digital to analog converter and a speaker attached. Links between computers and people are far better now though, so we can bypass the hard-to-learn instrument bit. With thought recognition, nerve monitoring, humming, whistling, gesture and expression recognition and so on, there is a very rich output from the body that can potentially be used far more intuitively and directly to generate the sound. You shouldn’t have to learn how to play an instrument in the 21st century. The sound creation process should interface almost directly to your brain as intuitively as your body does. If you can hum it, you can play it. Or should be able to, if the industry was keeping up.

Going a bit further, most of us have some idea what sort of music or effect we want to create, but don’t know quite enough about music to have the experience or skill to know quite what. A skilled composer may be able to write something down right away to achieve a musical effect that the rest of us would struggle to imagine. So, add some AI. Most music is based on fairly straightforward mathematical principles, even symphonies are mostly combinations of effects and sequences that fit well within AI-friendly guidelines. We use calculators to do calculations, so use AI to help compose music. Any of us should be able to compose great music with tools we should be able to build now. It shouldn’t be the future, it should be the present.

Let’s look at music distribution. When we buy a music track or stream it, why do we still only get the audio? Why isn’t the music video included by default? Sure, you can watch on YouTube but then you generally get low quality audio and video. Why isn’t purchased music delivered at the highest quality with full HD 3D video included, or videos if the band has made a few, with all the latest ones included as they emerge? If a video is available for music video channels, it surely should be available to those who have bought the music. That it isn’t reflects the contempt that the music industry generally shows to its customers. It treats us as a bunch of thieves who must only ever be given the least possible access for the greatest possible outlay, to make up for all the times we must of course be stealing off them. That attitude has to change if the industry is to achieve its potential. 

Augmented reality is emerging now. It already offers some potential to add overlays at concerts but in a few years, when video visors are commonplace, we should expect to see band members playing up in the air, flying around the audience, virtual band members, cartoon and fantasy creations all over the place doping all sorts of things, visual special effects overlaying the sound effects. Concerts will be a spectacular opportunity to blend the best of visual, audio, dance, storytelling, games and musical arts together. Concerts could be much more exciting, if they use the technology potential. Will they? I guess we’ll have to wait and see. Much of this could be done already, but only a little is.

Now lets consider the emotional connection between a musician and the listener. We are all very aware of the intense (though unilateral) relationship teens can often build with their pop idols. They may follow them on Twitter and other social nets as well as listening to their music and buying their posters. Augmented reality will let them go much further still. They could have their idol with them pretty much all the time, virtually present in their field of view, maybe even walking hand in hand, maybe even kissing them. The potential spectrum extends from distant listening to intimate cuddles. Bearing in mind especially the ages of many fans, how far should we allow this to go and how could it be policed?

Clothing adds potential to the emotional content during listening too. Headphones are fine for the information part of audio, but the lack of stomach-throbbing sound limits the depth of the experience. Music is more than information. Some music is only half there if it isn’t at the right volume. I know from personal experience that not everyone seems to understand this, but turning the volume down (or indeed up) sometimes destroys the emotional content. Sometimes you have to feel the music, sometimes let it fully conquer your senses. Already, people are experimenting with clothes that can house electronics, some that flash on and off in synch with the music, and some that will be able to contract and expand their fibres under electronic control. You will be able to buy clothes that give you the same vibration you would otherwise get from the sub-woofer or the rock concert.

Further down the line, we will be able to connect IT directly into the nervous system. Active skin is not far away. Inducing voltages and current in nerves via tiny implants or onplants on patches of skin will allow computers to generate sensations directly.

This augmented reality and a link to the nervous system gives another whole dimension to telepresence. Band members at a concert will be able to play right in front of audience members, shake them, cuddle them. The emotional connection could be a lot better.

Picking up electrical clues from the skin allows automated music selection according to the wearers emotional state. Even properties like skin conductivity can give clues about emotional state. Depending on your stress level for example, music could be played that soothes you, or if you feel calm, maybe more stimulating tracks could be played. Playlists would thus adapt to how you feel.

Finally, music is a social thing too. It brings people together in shared experiences. This is especially true for the musicians, but audience members often feel some shared experience too. Atmosphere. Social networking already sees some people sharing what music they are listening too (I don’t want to share my tastes but I recognise that some people do, and that’s fine). Where shared musical taste is important to a social group, it could be enhanced by providing tools to enable shared composition. AI can already write music in particular styles – you can feed Mozart of Beethoven into some music generators and they will produce music that sounds like it had been composed by that person, they can compose that as fast as it comes out of the speakers. It could take style preferences from a small group of people and produce music that fits across those styles. The result is a sort of tribal music, representative of the tribe that generated it. In this way, music could become even more of a social tool in the future than it already is.

Vampires are yesterday, zombies will peak soon, then clouds are coming

Most things that you can imagine have been the subject of sci-fi or fantasy at some point. There is certainly a large fashion element in the decision what to make the next film about and it is fun trying to spot what will come next.

Witches went out of fashion a decade ago even while other sword and sorcery, dungeons and dragons stuff remained stable and recurrent, albeit a niche. Vampires and werewolves accounted for far too many films and became boring, though admittedly, some of them were very good fun, so it’s safe to bury them for a decade or hopefully two.

Zombies are among the current leaders, (as I predicted several years ago, in spite of being laughed at back then). It is still hard to find a computer game that doesn’t have some sort of zombies in it, so they have a good while to go yet. The zombie apocalypse is scientifically and technologically feasible (see http://timeguide.wordpress.com/2012/02/14/zombies-are-coming/and that makes them far more disturbing than vampires and dragons, though the parasites in Alien are arguably even scarier.

Star Trek and the Terminator series introduced us to shape shifters. Avatar and Star Trek enthused over futuristic Indians. Symbionts and proxies are interesting but that’s really quite a shallow seam, there is really only one idea and it’s been used already. Religion and New Age trash has generally polluted throughout sci-fi and fantasy, but people are getting tired of it – American Indians and Australian Aborigines have been apologised to now. Recent Muslim backlash however suggests that the days are numbered for Star Wars, Dune, Mk 1 Klingons and others tapping into middle eastern stereotypes, so maybe  that will force other exotic cultures into the sci-fi limelight. The Cold War has already been done in overdose. South America has already been fully mined too. It’s a good while since the Chinese and Japanese cultures had a decent turn and I suspect they will come back strongly soon, whereas Africa doesn’t hold enough cultural identification points yet. Homophilia is having recurrent effects from Star Wars to Dr Who, but apart from gender-hopping, there isn’t really very far it can go. You can’t make many films from it.

So if those are the areas that are already showing signs of exhaustion  what comes after zombies? Gay zombies? Chinese zombies? Virtual zombies? Time travel zombies? Yeah, but after that?

Here’s my guess. Clouds.

Clouds are the IT Zeitgeist. They are the mid term future for sci-fi. There are a few possible manifestations and some tap well into other things we are getting to like. Clouds are a deep seam too. Not just one idea there. We have self-organisation, distribution, virtualisation, hybridisation, miniaturisation, self-replication, adaptation and evolution. We have AI, biomimetics, symbiosis, parasitic and commensalistic relationships. We have new kinds of gender, new kinds of intelligence, new physical and electronic forms. We have new kinds of materials, new ways of reproduction, new forms of attack and defense. I could write dozens of sci-fi books based on clouds. So could other people, and some of them will. Books, games, films, lots of them. About clouds.

You heard it here first. Clouds are the future of sci-fi.

 

The future of music and video media

With the death of HMV and Blockbuster this week, I’ve done some radio interviews on the future of the high street and one on the future of media. I wrote about retailing yesterday so today I’ll pick up on media. I wrote a while back that Spotify isn’t the future of music, not in its current form anyway, though I will admit that streaming is part of the future. Spotify will probably up its game and survive. If it doesn’t, it won’t. (I didn’t properly answer the question then of what the future would actually be. I will now.)

CDs aren’t the future of music either. DVDs or Blu-rays aren’t the future of video. Think about it. If you were starting from scratch today, would you base media distribution on plastic discs that have to be spun quickly in a mechanical device, and need to be read by lasers, are easily damaged, and take up lots of storage space? Of course you wouldn’t. You’d almost certainly go for either solid state or web storage. I’d go for solid state. Here’s why.

Web storage is fine as long as you have a good connection all the time and don’t have to pay for data downloads. I think we will still have streaming services in the far future and they might even remain a large market, but streaming isn’t a perfect solution. Transmitting data requires energy, and transmitting lots of data streams to lots of customers requires big server farms. It also clogs up bandwidth and that is limited too.

Downloading to local storage is also fine to a point. It is a large market now, and will remain so for some time. But there are also big problems with it. Licenses are not the same for downloaded music. You have a much more restricted ownership of music you buy online. The companies’ desire to protect their revenue is a higher priority for them that giving their customers full rights, just as it is with streaming (another reason streaming is not what it could be). With physical media, even though you may have ripped (and hence stolen) the content of the disc before you transferred it, the disc itself stops being yours if you pass it on to someone else. The concept of ownership and theft is very clear with physical media. With an MP3, less so. It is clear that the extra actual cost to the music provider is zero if you give a copy of an MP3 away, and you won’t buy a replacement anyway, and they probably wouldn’t either, so there is no clear revenue loss, so you can easily reason away any guilt in keeping a copy. So the music companies put in stuff like copy protection and non-transferable licenses that make it harder to keep your music organised, use it on multiple devices, recover it after disk crashes or sell it on when you’re bored with it. And with an MP3, you don’t have a nice box to look at and know that you own it. The music companies are more conspicuously stingy with MP3s too. If you are downloading the music, why don’t you get the music videos thrown in too? It’s obvious with the CD, there isn’t space on the disc, so you don’t mind, and the tradition has never been there anyway. A DVD could contain the video, but would cost more. With online music, you can usually watch it on YouTube so why don’t you get a proper decent resolution copy when you actually pay for it?

Anyway, solid state storage. I don’t want to be stuck with CDs or DVDs, and would much prefer to get a USB memory stick with the media on. I could plug it straight into my home cinema systems and watch a full Dolby Digital 7.1 Hi-def music video, preferably in 3D. I could easily play or transfer the files to any device I want. But that’s just today. Already, flexible displays and flexible batteries are appearing in electronics shows. It won’t be long at all before they are extremely common.

yoummain_2447820b

This is a demo flexible battery/display from Samsung. This is far more suited to carrying around and everyday abuse than glass. This could be a general purpose display but is also perfectly suited to be an all-round CD/DVD replacement, eventually. It will cost too much initially to directly replace CDs or DVDs or downloads, but the price of such devices is governed by Moore’s Law and will tumble. It could show you the music video or movie, it could hold the music or video, it could communicate with any of your display and audio devices as well as being one itself. It is collectable, and could hold a permanent album cover image or slideshow of video clips or stills. It could be of any shape and size and still do the job. It ticks all the boxes for ownership, portability, robustness, media future-proofing. The battery could be built in or it could be powered inductively, or using solar.

It could support a range of business models too. You could buy albums, one per device, just like CDs, proudly keeping them on a nice rack or display shelf. Resell them at car boot sales or give them to friends. Or you could subscribe to a band or a music producer, and it could hold all of their stuff, and be immediately updated with any of their new releases. It could be locked to just their stuff and just you if that’s what you bought.  The device could support lots of different kinds of license. Or you could buy stuff online and it would download to one you have as a replacement for today’s MP3 player. So it could hold one track, an album, a group, an entire collection, or be the front end device of a streaming service. Devices like this could support many business models. It meets the requirements of the music industry and the customer, doesn’t need lots of energy for cloud based storage, improves the potential quality of offering for everyone. This is the future of music media and probably video.

Of course you can do some of this with an app on a pad too. But having a dedicated device solves a lot of the problems we are used to that are associated with doing that.

What will your next body be like?

Many engineers, including me, think that some time around 2050, we will be able to make very high quality links between the brains and machines. To such an extent that it will thereafter be possible (albeit expensive for some years) to arrange that most of your mind – your thinking, memories, even sensations and emotions, could reside mainly in the machine world. Some (perhaps some memories that are rarely remembered for example) may not be suited to such external accessibility, but the majority should be.

The main aim of this research area is to design electronic solutions to immortality. But actually, that is only one application, and I have discussed electronic immortality a few times now :

http://timeguide.wordpress.com/2012/01/29/how-to-live-forever/

http://timeguide.wordpress.com/2012/01/21/increasing-longevity-and-electronic-immortality-3bn-people-to-live-forever/

What I want to focus on this time is that you don’t have to die to benefit. If your mind is so well connected, you could inhabit a new body, without having to vacate your existing one. Furthermore, there really isn’t much to stop you getting a new body, using that, and dumping your old one in a life support system. You won’t do that, but you could. Either way, you could get a new body or an extra one, and as I asked in passing in my last blog, what will your new body look like?

Firstly, why would you want to do this? Well, you might be old, suffering the drawbacks of ageing, not as mobile and agile as you want to be, you might be young, but not as pretty or fit as you want to be, or maybe you would prefer to be someone else, like your favourite celebrity, a top sports hero, or maybe you’d prefer to be a different gender perhaps? Or maybe you just generally feel you’d like to have the chance to start over, do it differently. Maybe you want to explore a different lifestyle, or maybe it is a way of expressing your artistic streak. So, with all these reasons and more, there will be plenty of demand for wanting a new body and a potentially new life.

Options

Lets explore some of the options. Don’t be too channelled by assuming you even have to be human. There is a huge range of potential here, but some restrictions will be necessary too. Lots of things will be possible, but not permissible.

Firstly, tastes will vary a lot. People may want their body to look professional for career reasons, others will prefer sexy, others sporty. Most people will only have one at a time, so will choose it carefully. A bit like buying a house. But not everyone will be conservative.

Just like buying a house, some rich people will want to own several for different circumstances, and many others would want several but can’t afford it, so there could be a rental market. But as I will argue shortly, you probably won’t be allowed to use too many at the same time, so that means we will need some form of storage, and ethics dictates that the ‘spare’ bodies mustn’t be ‘alive’ or conscious. There are lots of ways to do this. Using a detachable brain is one, or not to put a brain in at all, using empty immobile husks that are switched on and then linked to your remote mind in the cloud to become alive. This sounds preferable to me. Most likely they would be inorganic. I don’t think it will be ethically acceptable to grow cloned bodies in some sort of farm and remove their brains, so using some sort of android is probably best all round.

So, although you can do a lot with biotech, and there are some options there, I do think that most replacement bodies, if not all, will be androids using synthetic materials and AI’s, not biological bodies.

As for materials, it is already possible to buy lifelike full sized dolls, but the materials will continue to improve, as will robotics. You could look how you want to look, and your new body would be as youthful, strong, and flexible as you want or need it to be.

Now that we’re in that very broad android/robot creativity space, you could be any species, fantasy character, alien, robot, android or pretty much any imaginary form that could be fabricated. You could be any size or shape from a bacterium to an avatar for an AI spaceship (such as Rommy’s avatar in Andromeda, or Edi in Mass Effect. Noteworthy of course is that both Rommy and Edi felt compelled to get bodies too, so that they could maximise their usefuleness, even though they were both useful in their pure AI form.)

You could be any age. It might be very difficult to make a body that can grow, so you might need a succession of bodies if you want to start off as a child again. Already, warning bells are ringing in my head and I realise that we will need to restrict options and police things. Do we really want to allow adults people to assume the bodies of children, with all the obvious paedophilic dangers that would bring? Probably not, and I suspect this will be one of the first regulations restricting choice. You could become young again, but the law will make it so your appearance must remain adult. For the same obvious reasons, you wouldn’t be allowed to become something like a teddy bear or doll or any other form that would provide easy access to children.

You could be any gender. I wrote about future gender potential recently in:

http://timeguide.wordpress.com/2012/09/02/the-future-of-gender/

There will be lots of genders and sexuality variations in that time frame.  Getting a new or an extra body with a different gender will obviously appeal to people with transgender desires, but it might go further and appeal to those who want a body of each sex too. Why not? You can be perfectly comfortable with your sexuality in your existing gender, but  still choose a different gender for your new body. If you can have a body in each gender, many people will want to. You may not be restricted to one or two bodies, so you might buy several bodies of different ages, genders, races and appearances. You could have a whole village of variants of you. Again, obvious restrictions loom large. Regulation would not allow people, however rich or powerful, to have huge numbers of bodies running around at the same time. The environmental, social, political and military impacts would get too large. I can’t say what the limits will be, but there will certainly be limits. But within those limits, you could have a lot of flexibility, and fun.

You could be any species. An alien, or an elf, or a dog. Technology can do most shapes and as for how it might feel, noone knows how elves or dogs or aliens feel anyway, so you have a clean slate to work with, customising till you are satisfied that what you create matches your desire. But again, should elves be allowed to interbreed with people, or aliens? Or dogs? The technology is exciting, but it does create a whole new genre of ethical, regulatory and policing problems too. But then again, we need to create new jobs anyway.

Other restrictions on relationships might spring up. If you have two or more bodies, will they be allowed to have sex with each other, marry, adopt kids, or be both parents of your own kids. Bear in mind cloning may well be legal by then and artificial wombs may even exist, so being both parents of your own cloned offspring is possible. If they do have sex, you will be connected into both bodies, so will control and experience both sides. It is worth noting here that you will also be able to link into other people’s nervous systems using similar technology, so the idea of experiencing the ‘other’ side of a sex act will not be unique to using your own bodies.

What about being a superhero? You could do that too, within legal limits, and of course those stretch a bit for police and military roles. Adding extra senses and capabilities is easy if your mind is connected to an entire network of sensors, processors and actuators. Remember, the body you use is just an android so if your superheroing activity gets you killed, it is just a temporary inconvenience. Claim on insurance or expenses and buy a new body for the next performance.

In this future world, you may think it would be hard to juggle mindsets between different bodies, but today’s computer games give us some insight. Many people take on roles every day, as aliens, wizards or any fantasy in their computer gaming. They still achieve sanity in their main life, showing that it is almost certainly possible to safely juggle multiple bodies with their distinct roles and appearances too. The human mind is pretty versatile, and a healthy adult mind is also very robust. With future AI assistance and monitoring it should be even safer. So it ought to be safe to explore and have fun in a world where you can use a different body at will, maybe for an hour or maybe for a lifetime, and even inhabit a few at once.

So, again, what will your next body look like?

Casual displays

I had a new idea. If I was adventurous or an entrepreneur, I’d develop it, but I’m not, so I won’t. But you can, before Apple patents it. Or maybe they already have.

Many people own various brands of pads, but they are generally expensive, heavy, fragile and need far too much charging. That’s because they try to be high powered computers. Even e-book readers have too much functionality for some display purposes and that creates extra expense. I believe there is a large market for more casual displays that are cheap enough to throw around at all sorts of tasks that don’t need anything other than the ability to change and hold a display.

Several years ago, Texas Instruments invented memory spots, that let people add multimedia to everyday objects. The spots could hold a short video for example, and be stuck on any everyday object.These were a good idea, but one of very many good ideas competing for attention by development engineers. Other companies have also had similar ideas. However, turning the idea around, spots like this could be used to hold data for a  display, and could be programmed by a similar pen-like device or even a finger touch. Up to 2Mb/s can be transmitted through the skin surface.

Cheap displays that have little additional functionality could be made cheaply and use low power. If they are cheap enough, less than ten pounds say, they could be used for many everyday purposes where cards or paper are currently used. And since they are cheap, there could be many of them. With a pad, it has to do many tasks. A casual display would do only one. You could have them all over the place, as recipe cards, photos, pieces of art, maps, books, body adornment, playing cards, messages, birthday cards, instructions, medical advice, or anything. For example:

Friend cards could act as a pin-board reminder of a friend, or sit in a wallet or handbag. You might have one for each of several best friends. A touch of the spot would update the card with the latest photo or status from Facebook or another social site. Or it could be done via a smart phone jack. But since the card only has simple functionality  it would stay cheap. It does nothing that can’t also be done by a smartphone or pad, but the point is that it doesn’t have to. It is always the friend card. The image would stay. It doesn’t need anything to be clicked or charged up. It only needs power momentarily to change the picture.

There are displays that can hold pictures without power that are postcard sized, for less than £10. Adding a simple data storage chip and drivers shouldn’t add significantly to cost. So this idea should be perfectly feasible. We should be able to have lots of casual displays all over our houses and offices if they don’t have to do numerous other things. In the case of displays, less may mean more.

The future of gender

Warning: this is a 10,000 word entry, not my usual page or two

Introduction

Scope Limitation

I lecture occasionally about the future of sex, but I find gender as a whole is a fascinating subject. I don’t want my blog to get x-rated so need to be a bit careful what I cover and how, but I do think the future of gender is a topic worth writing about and I don’t need to get all adulty to make it interesting. If you are adult, you can use your own imagination to colour in any areas left uncoloured. Having said that, I’d still prefer you don’t proceed if you are under 18 or easily upset. I will cover this as far as I can.

I must also apologise at the outset that I haven’t managed to organise my thoughts on this very well. There are a number of dimensions to consider and it doesn’t lend itself well to a one dimensional article. There are probably some huge gaping holes in my coverage, even though this is a 10,000 word article. I think of this as an early stage in my thinking and therefore as a work in progress. I would welcome and thoughts on areas I have missed, and some of you will also have personal and first hand gender change experiences that are quite alien to me, that I would like to learn about. Although Einstein relied on it, and I love to copy his example, you simply cant do everything by thought experiment.

What is gender?

Wikipedia’s entry on gender is disappointing and seems lacking in scope. It is typical of academic treatments all too common in Wikipedia that use formality, obfuscation and unnecessary addition of superficial details in place of completeness of scope, understanding or insight. Nevertheless, it serves as a basic foundation on which to build. Its definition of gender:

“Gender is a range of characteristics of femininity and masculinity.[1] Depending on the context, the term may refer to such concepts as sex (as in the general state of being male or female), social roles (as in gender roles) or gender identity.”

Its gender taxonomy is adequate:

chromosomes may be 46xx, 46xy, 47xxy (Klinefelter’s syndrome), 45xo (Turner’s syndrome), 47xyy, 47xxx, 48xxyy, 46xx/xy mosaic , other mosaic, and others.

gonads may be testiclesovaries, one of each (hermaphrodites), ovotestes, or other gonadal dysgenesis

hormones: androgens including testosterone; estrogens — including estradiol, estriol, estrone; antiandrogens and others

and of course genitals, but also secondary characteristics such as breasts,

there are also differences such as

brain structure -special kinds of secondary characteristics, due to their influence on psychology and behaviour

gender identity – psychological identification with either of the two main sexes

gender role – social conformity with expectations for either of the two main sexes and finally

erotic preference - gynophilia, androphilia, bisexualityasexuality and various paraphilias.

I really hope those keywords don’t cause me any problems.

At least that is all pretty clear, but it is clearly pre-IT thinking and too medically oriented so misses a lot of importance. Humans are advanced animals, and their brains and accumulated culture add a great deal of extra scope beyond what nature bequeaths to most creatures. There is no mention in the article of the huge degree of virtualisation, abstraction, compartmenatilisation, multi-dimensionalism or parallelism of gender common in virtual worlds, dream-space and social media and the associate impacts in real world psychology. It is purely two dimensional, recognising genetic and social gender but still only male or female. I don’t believe for a moment that gender has suddenly changed beyond recognition or that sociologists must all be blind, so I can only infer that the discipline of gender studies is deliberately self-restricting. I can’t imagine why.

I don’t normally bother with definitions anyway, preferring to live in an analog world where common sense rules. I certainly don’t recognise the Wikipedia one as anything other than of historical interest. But let’s start with it as just that, assuming the last 30 years hasn’t happened yet and that everyone is still hiding in a Victorian closet.

Male, female, what else for physical gender?

Male and female isn’t a bad starting point per se. Natural sexuality uses just two sexes. In the 1990s, a few of my BT colleagues did a study on the numbers of sexes that should be used in genetic algorithms (a method of engineering using random mutations on ‘genes’, which are typically options for algorithms, and fitness testing, loosely based on Darwinian evolution). They found that the optimal number of sexes averages between 2 and 3. Two is fine, and nature ran with it. But you could have 3 or 4 or any number. It isn’t optimal from an evolutionary perspective, but it is for purpose and that is all nature needs.

There aren’t any common names for additional genders yet, though I am sure names exist within subcultures. Sure, we have male, female, neuter and hermaphrodite and lots of intersex variants, some of which do have names, but that is just one physical dimension and even so, there is some overlap among the names, and disagreement and confusion as to their precise meaning. When we start to add extra genders, there will be far more possible combinations.

New chromosomes

Initial (birth) physical gender in nature is largely determined by genes. Usually, two X chromosomes make a girl, and an X and Y create a boy. Even then, things can go wrong and some competitive sports issues have been raised in recent years by mismatches between chromosomal state and physical appearance, resulting in arguments over the gender of a winner and their consequential right to compete in that event. It is possible to have X and Y or two Xs and a Y and yet be born with an apparently female body. Before we start on designing new kinds of chromosome, let’s look briefly at what we might be designing them for.

Opportunity for new gender dimensions

Humans treat sex as a recreational and social activity as well as a reproductive one. Some future genders may be involved in reproductive processes and some may not. Some associated activities may generate sexual pleasure, others may not. Some genders could have roles as ‘bridges’ between two or more other genders, not directly providing any of the genes for future offspring, but involved as a necessary link in the reproductive process, as simple carriers, or genetic filters or processors. Regardless or the biological simplicity or complexity of the role, the organs, gender identity, social roles, rituals, and so on are essentially orthogonal dimensions, so could be designed pretty independently. The timelines for different types would not necessarily be similar, and designs could evolve over time. Obviously, making a new gender capable of reproduction is more difficult than just making a few cosmetic features, especially ones that aren’t deeply woven into the sensory or emotional or sexual response systems.

Adding new reproduction-capable genders or sexes will presumably require synthetic biology to create new genes, as well as a great deal of imagination and creativity to decide what gonads, genitals, other organs and sexual features to add. There is little point in speculating yet what they would look like, because it is a completely open space for creativity and experimentation.

Suppose as well as an X or Y, we were to add A, B, C… and Z chromosomes to carry the genes for them. They would need designed to achieve the features desired, but engineers will be able to do that in due course. We don’t yet understand how to design DNA to achieve particular features, but it is only a matter of time before we will. We will also one day be able to make DNA alternatives so won’t be limited by its capabilities. Physics and biology certainly allow it, the market will demand it, and engineers will build it. There are different ways of proceeding. We could end up with 3 or more chromosomes, or we could just modify existing ones to incorporate modified genes. Maybe only one type of cell is affected, or a few, or maybe all. Synthetic biology is a relatively open design space.

However, we choose to do the bio-engineering, by the end of this century, there could be a range of biological sexes  to add to male and female. We will still have neuter, male, female, and hermaphrodite, but also gender A, B, C, …,  multi-gender, hybrid genders, and so on ad infinitum. People may be able to pick any blend of them for their offspring.  Instead of two genders and a few mutations, we will have lots.

Associated practices

Creating new types of sex organs and associated mating practices is one thing, but the whole of sexuality could be redesigned at the same time. These new sexes will often interact in completely new ways. There will be arguments over whether some should be classed as new species since not all will be able to interbreed with traditional humans.

New gender roles, identities and erotic preferences would all have to be designed and engineered. It would be possible to engineer what makes attractiveness to a particular type of person of a particular gender. This isn’t all new, sci-fi writers have included inter-species relationships for decades, though they have generally stuck with traditional male and female in each species. But at least they have got as far as working out some attractive features and rituals, for Klingons at least. Where there is a big gap is in the scope for many genders being involved in an interaction, rather than the traditional one or two. To paraphrase Peter Cochrane, we don’t have six genders in nature because the chances of six people getting together at once without any of them having a headache is minimal. We will one day have gender designers and engineers working with sociologists, neuroscientists and many other disciplines to come up with new genders, roles, practices, rituals and attractiveness design.

Full Transgender

Change of physical gender today requires a lot of pain and mental stress, and isn’t something undertaken lightly. Even after all that, biotechnology still can’t offer a full chromosomal change and cosmetic surgery can only accomplish so much, so the changes are limited to outward appearance, organ reassignment and hormone medication. Results vary considerably in achieving a convincing change. Perhaps one day, if much hyped nano-medicine ever achieves its full potential, a full chromosomal retrofit and body reshaping may be possible so that the person becomes how they would have been had they been born their chosen gender. In that scenario, if the technology can do all that, then it can probably also achieve pretty much any body design desired, so gender change may be be just one option in a long selection of major body redesigns, way behind youth restoration in popularity. In the extreme, an average looking middle aged man may be able to change into an attractive young woman. And it need not be permanent, they could change back, though I wouldn’t expect much of a queue of attractive young women wanting to become middle aged men.

It is unlikely that it will become easy to change gender physically, so however much it may appeal as a concept, frequent recreational gender changing of their physical body is unlikely. It will still be something people do once at most.

Neural linking of external technology

Many people are well used to gadgetry in sex, some leave that kind of play for others. A variety of means are used to create stimulation, but electronic stimulators particularly hint at what the future offers. Stimulation is generated by using cleverly designed toys with electrodes that generate variable voltages and frequencies into relevant parts. In the next decade or two, active skin will use electronics printed directly on to the skin surface, along with some that penetrates deep into the skin to connect to nerve endings, enabling recording and replaying of sensations. It can then be expected that the sophistication, capability and personalisation of sex devices will increase dramatically.

It is possible that in the future, a variety of strap-ons, harnesses, sheaths and plugs will exist that not only create intense sexual stimulation, but do so from a library of recorded experiences, or indeed those downloaded from others. Future porn may well include recorded experiences from or with other people, and of course just like conventional porn, these could be enhanced with the neural equivalents of Photoshop. Further in the future, when we understand the brain better, and can engineer direct links into it, it may be that areas of some people’s brains may be modified or taught to treat the sensations from these devices as if they were truly part of their bodies.

This then reopens the scope for modification of gender. For example, it may be possible for a woman using a strap-on to feel as if it were an actual part of her, getting appropriate sensations from it. This could be sensations appropriate to males, or specially designed new ones for women. This is the most likely starting point for another class of gender modification. Toys could be added to an otherwise conventional body and linked into the nervous system and/or brain so well that they allow true full sensory transgender play. They could also be added alongside other sexual organs and sensations or, by perhaps using TMS-based signal attenuation, it could displace the original sex sensations. By generating another dimension for gender play, it greatly increases the scope for gender fluidity. When mixed with multiple genders, of course the scope increases still further.

The person wearing the device may well experience a convincing change in gender from a purely sensory point of view, but their outward appearance to another person would still be that of someone of original gender wearing a device. Outward appearance matters, but a convincing visual change to match the assumed gender could be done using augmented reality. Augmented reality adds another huge area for gender change and experimentation and deserves its own section later.

Unlike permanent transgender operations, these devices could be attached and detached at will, allowing people to oscillate freely among genders, opening the door to recreational gender change.

Recreational gender change

These future sex toys will allow a high level of sensory immersion in a different gender. Their use and popularity is evidenced by the high level of recreational gender change that  already features heavily in virtual worlds. Virtual worlds have many applications, but highly relevant to gender play, they are often used for computer games and for socialising, often combining both. They are also heavily used for role play, exploration of new places,, cultures and experiences and experimentation.

Gender identity is a bit more fluid than Wikipedia suggests. People role play different genders frequently in computer games and social virtual worlds and the experience can vary across a broad spectrum from totally detached and 3rd party to fully immersive. Sometimes, people may compartmentalise the experience, so they remain fully their normal gender in their real life while playing as another in a game or in a virtual world. Or they might become fully immersed in the role and feel as if they are the other gender for a while. Over prolonged sessions, their gender identity may blur somewhat.

Gaming

In gaming, people generally play as a character, such as a soldier or superhero, a wizard or alien. They explore worlds that range from totally fantasy to those based on real places and real life. Sometimes, games give a choice of character, and often people will play as a character of different gender to themselves. Men often play as female characters even if they don’t have any transgender intent. The standard justification is that they since they are looking at the world through a viewpoint just behind their character, they would rather look for the next 30 hours at an attractive female rear than a male one. Of course, it may also just be fun playing at being female for a while and then the role play can become a superficial gender change experience. Women gamers would find it hard to avoid having to play as a male character occasionally, since many games are designed with only male playable characters. Either way, games are a simple and painless way of exploring another gender superficially.

Virtual worlds and social networking

Such gender changing becomes a step more real once the game allows interaction with other people. It may still be in the context of a game or role play, but there is a wider spectrum of role play with other real humans involved rather than just lines of computer code. In a game, the real person hides behind their online gamer persona, which then hides behind the game character’s avatar. There is still little social risk since the game offers the excuse to play, but the degree of immersion into the other gender is consequently limited too.

When the game is removed and it becomes primarily a social networking world, like World of Warcraft or Second Life for example, the player is a step closer to their avatar and their immersion in the gender of their avatar is more real. The deliberate choice of gender and name for their avatar at the outset creates an extra level of buy-in. They are self-representing in a way that a computer game character isn’t. Choosing a different gender from their normal self is an act of minor but nevertheless deliberate deception. In spite of that, though some people may present in their normal gender, the temptation to try out a different gender at least once is irresistible to most people. About three quarters of people in virtual worlds and chat rooms have tried presenting as a different gender and some do so very often.

When they present as a different gender, the player must then consider not only what they look like to themselves on the screen, but how they present themselves to others and how they are seen. They also have to consider their personality, and the degree to which they modify that to support their virtual gender change. The level of association with the avatar varies from person to person and from time to time, but the result is that virtual gender play varies all the way from frivolous to deeply immersive and self absorbing in way that the person genuinely feels themselves to be the presented gender. It seems reasonable to say that although playing a different gendered character in a computer game isn’t always gender play, doing so in an online social context probably always is, even if it is temporary and far less committing than full gender reassignment. By being forced to interact personally rather than just hitting buttons on a controller, the buy-in crosses the boundary. Before looking at the future of this, we need to mention filters.

Filters

Reality TV is based in large part on the huge gulf that can occur between the image someone thinks they project and what is perceived by the viewer as reality. We see the world, other people and even ourselves through a series of filters. These are at least as important in gender play too.

Since people generally haven’t any actual experience of fully being another gender, they can only experience their virtual trans-gender through context-specific filters. When presenting to other people as a different gender in a virtual world, several of these filters come into play and they add another dimension.

Firstly, the superficial gender that is presented means different things to different people – beyond agreeing on genitalia, we don’t all share exactly the same prejudices about what male or female mean. People build up a picture in real life of how it must feel to be another gender and can play to that image but have no way of benchmarking that with real life feeling.

Secondly, no-one knows exactly how a particular image would be perceived by another. All they can do is to use their interactions with others as feedback on how convincing they may be.

Thirdly, even given an image that someone wants to project, there is another error in the actual presentation of it – there is no perfect feedback system that lets someone see accurately how others perceive what they think they are projecting.

Fourthly, there may be a fetishist bias to project an image that appeals to the tastes and fetishes of the person changing gender themselves. In such cases, the outward superficial appearance is what matters most to the person, and the acting out of a fantasy, rather than the immersion in the other gender.

So there are errors in presentation, interpretation and difference of meaning, and the experience of gender change may be diluted by other accompanying role plays.

Degree of reality

The other person may initially see someone in the gender they present, but anyone familiar with online social networking will learn to suspect a gender mismatch so they won’t necessarily accept it at face value. They may or may not know the person’s real gender, they may only believe it to a point, or they may realise they are presenting an alternative one. But they may not care. The same excuses for presenting a false gender may still  be successfully offered if the player doesn’t want to admit to any transgender feelings, but gender play is so common online that few would really care. It is a lightweight way of experiencing gender play with others. The lower threshold for gender acceptance also means that the reality of the experience is reduced, since people don’t necessarily treat others as they would someone whose gender they are sure of.

Other social sites

In non-play social sites, role play isn’t assumed and the self is more exposed. Some sites such as Google+ enforce the use of real identity, others such as Facebook don’t. Gender play on social networking sites is therefore not as socially acceptable as in virtual worlds where it is considered a routine part of role playing.

Virtual worlds ought to be a place where new genders should emerge. The main barriers preventing this in the real world don’t exist, though there are still barriers of culture and imagination.  So we should expect virtual worlds to be the first places for trying out new genders, with their associated cultural baggage, practices and rituals.

Future virtual worlds will have better graphics, full 3d immersion and eventually sensory recording and replay. The quality of communication with others and the quality of shared experiences in 3d realistic environments and situations will increase proportionately. These will make them a more realistic and immersive exploration of the other gender too, and will increase the overall feeling of reality of the experience.

What does the absence of new genders in virtual worlds teach us?

The lack of new genders on virtual worlds is interesting. People are certainly enthusiastic about experimenting. Changing into robots, drones, monsters, animals, furries, aliens, dolls, even objects is commonplace, and swapping between genders is also commonplace, but apart from male, female, neuter and some shemale variants, there conspicuously aren’t any other genders. Is this just failure of imagination, or does it simple reflect the fact that people are coming from an existing state with its associated sexual preferences, and are therefore only drawn to these options? The latter seems the more likely explanation.

Immersion

Thanks to these filters, the degree of reality of gender changing experiences available in virtual worlds is highly variable, both to the person undergoing the gender change and to other people interacting with them. Adding future technology increases the potential sensory quality, but won’t necessarily change the social assumptions or trust. If the gender changing is just fetishist self-voyeurism or role play, then that may not matter much, but if the intent is to pass as the other gender then it would matter more.

Interaction in virtual worlds today is often just via text chat and animations, but voice changing technology may also be used to pretend in a little more depth. As this improves in quality, it may allow people to pass as an alternative gender much more easily and convincingly. Avatars can be made to look any way, and they will improve in quality over time too. They will become full 3d and some virtual worlds may become fairly convincing replicas of real life.

Artificial intelligence can also play a part, acting as a real time coach and filter, changing the outward presentation of a gender by altering or enhancing mannerisms, gestures and other body language, use of verbal language, such as choice of words, phrases, style, subject matter, the lengths of sentences and other clues to gender.

At that point we will really start to see crossover of the technology into other forms of chat, with webcams able to change video image, conversational style and content and voice in real time to allow people to pass in real life chat situations as another gender. Some may do so only in social interactions, others may use it for work too.

In chat rooms, ever since they started, some people have presented as different genders, so anyone’s friends lists will include some people whose real gender they know for certain, some they know for certain are gender-bending, and some in between, where there are varying levels of suspicion that they may not really be their presented gender. Virtual worlds added even more play potential, and soon webcams will increase it further still. Soon, thanks to the trend of working from home, we may not know the genders of the people with whom we are working. Not knowing the genders of all your friends is not new, but it also isn’t ubiquitous. Many people have never used a chat room or virtual world, so have no first hand experience of gender confusion. No doubt some people would consider it to be a social problem if people frequently present as another gender from time to time, others will feel perfectly comfortable with it.

Augmented reality

Augmented reality is a bit different from this, offering more scope for change and adding still more new dimensions to gender play. AR allows computer generated images and data to be overlaid onto the field of view. This started off in everyday practice with simple text and symbols on smart-phone screens, but the idea space is over 20 years old now, and only the technology is holding back realisation. It will quickly evolve into a fully immersive overlay capability where the uses can selectively overlay or replace real world images with computer generate ones. So, virtual architecture may modify the appearance of buildings or streets, virtual fauna and flora will decorate them, and people can be cosmetically enhanced or simply replaced by avatars. That means a user could make all the ugly people look prettier, replace them with images of their favourite celebrities, or just delete them from the field of view (though some mechanism is needed to prevent collisions when they are physically close).

There are a number of choices that make it interesting.

Firstly, who controls how one person sees another. Is it the viewer, or the person being seen, or some third party such as an application or service provider?

Can someone assert their chosen edited appearance on the viewer, and can they do so differently for each group of potential viewers, or tailor how they appear to the context and specifics of that interaction? All of the above?

Does the viewer get to choose between an avatar and a real life image, even if an edited one, or an alternative avatar, or a cosmetically enhanced appearance, or is that also decided by the person being seen?

If the viewer has control, can they also choose the gender of the other people they see?

Can the person being seen assert their chosen gender, and hide their real one from the image production system?

Should there be a right to see how someone else is visualising you, or even how they are visualising others? If so, under which circumstances? Should the police be able to check that your visualisation of someone else isn’t demeaning or insulting, or a race crime? Should your use of overlays be forced to be recorded in case it needs to be policed in future?

Obviously, these choices give a lot of options for potential gender interactions. As well as gender, images could also show people with different ages, races, even species, or as an object, as someone else, or as a group of people, or show a group as an individual. Someone playing a character in a computer game or virtual world may find it fun to use that same character avatar on the high street. A full AR replacement of people in the street could be a very different world to live in.

There would be some social pressure on application providers to prevent too much abuse of such systems, but also some demands from minority groups to protect their specific interests. It seems reasonable that a transgendered person or a transvestite should have the right to present themselves as their chosen gender. Since someone may be just exploring gender options prior to considering becoming transgendered, that right would also need to extend to casual recreational gender change. But that only requires that their original gender be concealed from the viewer or system. It doesn’t prevent the viewer from replacing or modifying what they see. They could still replace any stranger’s image with a customised one of their own choosing, and it isn’t necessary to know anything about the stranger to do so. So it is possible to protect transgender rights while still allowing viewers to choose how they modify the world they see.

Augmented reality also allows people to select and apply components of how they (or an application provider) believe other genders might feel by changing the appearance of the world to that ideal. Certain parts of images may be enhanced or dulled to reflect the relative importance. A crude example may be feminising it by adding more pinks or flowers or children or female oriented ads. Hopefully, the reality would be a little more sophisticated.

Augmented reality will objectify women

Our treatment of others varies according to how we perceive their gender.

Augmented reality will bring many benefits and improve our lives in many ways, such as enjoying virtual architecture, playing immersive computer games while a partner is shopping, or enjoying artworks transposed onto walls in the high street. But it won’t all be wonderful.

In spite of marketing hype and misrepresentation of basic location based services, AR is only here in very primitive form today, outside the lab anyway. But very soon, we will use visors and contact lenses to enable a fully 3D, hi-res overlay on the real world. So notionally, someone can make everything in the world look how they want, but only to a point. They can transform a dull shop or office into an elaborate palace of spaceship. But even if they change what these look like, you still need to represent real physical structures and obstacles in your fantasy overlay world, or they may bump into them, and that includes all the walls and furniture, lamp posts, bollards, vehicles, and of course other people. Augmented reality allows us to change their appearance thoroughly but they still need to be there somehow.

When it comes to people, there will be some small battles. Each of us may have a wide variety of avatars, and may have invested a great deal of time and money making or buying them. Someone may have a digital aura, hoping to present different avatars to different passers-by according to their profiles. They may want to look younger or thinner or as a character they enjoy playing in a computer game. They may present a selection of options. The avatar they choose to overlay could be any one of the images on offer, that they spent so much time on. Maybe some people get to pick from several on offer, or are restricted to just one that is set for their profile type.

However, other people may choose not to see that avatar, but instead to superimpose one of their own choosing. The question of who decides what the viewer sees is the first and most obvious battle in AR and it will probably be won by the viewer (there may be exceptions, and these may be imposed by regulations). The other person will decide how they want to see you, regardless of your preferences.

Someone could spend a great deal of time making an avatar or tweaking virtual make-up to perfection, but if someone wants to see Lady Gaga walking past instead of them, they will. A stranger’s body becomes no more than an object on which to display any avatar or image someone else chooses. People are quite literally reduced to an object in the AR world. Those with concerns over objectification of women will not like what AR will bring.

Firstly they may just take an actual physical appearance (via a video camera built into their visor for example) and digitally change it,  so it is still definitely still the target person, but now dressed more nicely, or dressed in sexy lingerie, or how they might look naked, body-fitting any images from a porn site. This could easily be done automatically in real time using some app or other. They could even use the actual face as input to image matching search engines to find the most plausible naked lookalikes. So anyone can digitally dress or undress anyone, not just with their eyes, but with a hi-res visor using sophisticated software and image processing software. They could put anyone in any kind of outfit, change their skin colour or make-up, and make them look as pretty and glamorous or as slutty as they want. The victim won’t have any idea what someone looking at them is seeing. They simply won’t know whether they are being treated with respect, flattered, or made to look even prettier, which they might not mind, or perhaps being digitally stripped or degraded which they probably will mind a lot.

Anyone can treat anyone else as just an object on which to superimpose some other avatar, which could be anything or anyone, a zombie, favourite actress or supermodel. They won’t need consent and again the victim won’t have any idea what the viewer are seeing. The avatar may make the same gestures and movements as the real person. In some ways this won’t be so bad. People are still reduced to objects but at least it isn’t that particular individual that they’re looking at naked. Most strangers on the high street were just moving obstacles to avoid bumping into anyway. Most people will cope with that bit. It is when interaction starts that it starts to matter. Many people won’t enjoy it if someone is chatting to them but looking at someone else entirely, especially if they are a friend or partner. Kissing one person while looking at someone else would be a breach of trust. This sort of thing could and probably will damage a lot of relationships.

It’s a fairly safe bet that the software to do some or all of this is already in development. Maybe some of it already exists in primitive forms but it will develop quickly once AR display technology is really with us. The visor hardware required is certainly on its way and primitive versions will be here by the end of 2012.

In the office, in the home, when you’re shopping or at a party, people won’t have any idea what or who someone else is seeing when they look at them. The main casualty will be trust.  It will make us question how much we trust each of our friends and colleagues and acquaintances. It will build walls. People will often become suspicious of others, not just strangers but friends and colleagues. Some people will become fearful. People may dress as primly as they like, but if the viewer sees them in a slutty outfit, perhaps their behaviour and attitudes will be governed by that rather than reality. So there could be an increase in sexual assault or rape. Women especially may more often be objectified, in more circumstances. Many men objectify women already. In the future AR world , they’ll be able to do so far more effectively without everyone knowing.

Augmented reality accessories

It is possible to use virtual accessories as well as real ones. An augmented reality strap-on or vibrator may look similar to a real one, but of course doesn’t have the same physical presence and the same goes for any other imagined accessory for any future gender. If it is to have anything more than a symbolic presence in role play, it needs somehow to connect into the nervous system or at least to be able to create some sort of sensation. Linking a virtual accessory to the peripheral nervous system can be done via active skin, pressure pads, smart gloves or data suits. In the far future it may be possible link directly into the brain. There are lots of options.

The potential to make augmented reality accessories that can be associated with real sensations and take a real part in gender–related practices allows new genders to come into play long before they are possible to make genetically.

However, we must ask just how ‘real’ such genders would be. The people using such virtual appliances may take part in interesting experiences, but their original body and original gender remains intact unless they undertake further action.

It is possible to have original equipment disconnected or removed, and to use the augmented reality devices instead. It may also be possible to block or attenuate the sensations from them at the brain using derivatives of trans-cranial magnetic stimulation or some future signal blocking means. With this associated physical gender reassignment, augmented reality would offer a proper means of gender change with less trauma.

Once we start linking to the peripheral nervous system, we can dissociate the physical acts causing a stimulus from the sensation experienced. Though frivolous and perhaps ridiculous, it is entirely possible to create intense sexual sensation or even orgasm just by typing a capital O on a keyboard, or by any other action.

The existing nervous system is limited in its scope though, and it would be better to be able to map sensations onto new areas of the brain. Thanks to research and development on tools to help disabled people interpret the world around them, we know that the brain is able to accept stimuli and learn to interpret and experience them over time. This again offers scope for new genders before we get to building them genetically.

Compartmentalising and acting

Humans are skilled at presenting filtered or enhanced views of themselves to others. We talk of wearing a shield or a mask. We all do it all the time, at work and socially, presenting edited personas to different groups.

Some people are very good at it and become actors. The acting profession is a good point to look for gender insight. Actors often complain that people treat them as if they were the character they play, which shows that for some people, the line between fiction and reality can sometimes get blurred. Presumably, that would make it easier for them to take people’s presented gender at face value and perhaps not even consider whether it may be faked.

Another clue from acting is that actors sometimes practise for a role by immersing themselves in the character’s situation, so that they can begin to identify with it more closely and play the role more naturally. In essence they are deliberately blurring the lines of their own fiction and reality. Or at least part of it.

From birth, we start registering differences between male and female. Each of us forms a unique view of how it is to be our own gender and how it might feel to be another. If we try to act as if we were another gender, that is the prejudice we have to start from. To improve on that, some people live part or full time in the guise of the other gender, just as actors may live in their character. Gender reassignment surgery usually follows a lengthy period of such living, since it isn’t properly reversible, yet. This ensures that the person feels comfortable in their new gender before the final commitment. They will experience others’ reactions to themselves but may also feel differently while in the other gender. The playing of the new role is important because it changes how someone feels inside, not just how they look outside.

Recreational gender changing is temporary in nature and therefore lends itself more to compartmentalising rather than essentially practising a new life. Again, like acting, someone knows who they ‘really’ are, but allocates a sub-mindset to play their role. Someone presenting themselves as another gender in a chat room or virtual world is likely compartmentalising. They have a normal everyday life as one gender, but play act with a particular mindset in their chat room role.

There isn’t a limit on how many roles someone can act. In everyday life, we all have dozens of slightly different personas to cover all the different social groups we belong to. In chat rooms and virtual worlds, people often have several alternative personas, or alts. Some people use over twenty regularly. That is easy to understand, but what is surprising is that they manage successfully to use several at the same time. They may even have one of their alts apparently chatting to other ones so that they can maintain the pretence. This requires a degree of skill to keep them all separate and prevent others from suspecting. But it is exactly that skill that also allows someone to compartmentalise gender. People may have some alts in one gender and some in another. Some may flip between them. They use the appropriate gender filters to present each one according to circumstance.

Such compartmentalisation skill is common, and shows that some people will be adept at doing so with future genders too. They will have to juggle lots of roles, with all the associated memory and behaviours, and they will do so in games, chat rooms, social networking sites, virtual worlds, and augmented reality overlays, and in a wide variety of everyday business and social interactions, but they will have AI to help them translate body and verbal language between them, handle all their avatars, and even act in their place or alongside when they are not sufficiently present. We can only expect gender to become even more blurred and dynamic as recreational gender play becomes more powerful and immersive.

Blurring of gender identity

That raises the question of degree to which someone’s psychological gender identity can blur as a result of frequent recreational gender play. If someone puts effort into presenting as another gender for significant periods, running the appropriate emulators alongside the normal ones, it is inevitable that they will gradually adopt some of what they consider to be the attitudes of the other gender, and some behaviours will cross over into their other compartments. The various models all have to access some of the same underlying thinking and control processes – they won’t all be duplicated and kept separate – so the appropriate neural circuitry and skills will change accordingly. This must be especially so in areas that don’t get shielded from outsiders, the ones they don’t think of as particularly visible or gender-relevant, because they are less careful to keep them in separate compartments. Over time, their gender identity will inevitably blur. This may well make them more accepting and tolerant of the other gender, but if they are frequent recreational gender changers, that is unlikely to have been an issue in the first place.

Dreams

Dreams are related to games and virtual worlds. They share some of the same mental emulation of a perceived reality, albeit in dreams the emulator is heavily distorted and filtered. Some people sometimes dream of themselves in another gender. It may feature as a central part of the dream storyline, perhaps that somehow they have been transformed, it may be that they just happen to be that gender, or it may be purely incidental, not particularly relevant to the storyline. Or it may be a way of indulging in an aspirational gender change for someone who has transgender thoughts. In lucid dreams, it can even be a form of recreational gender change.

Which brings us nicely to the idea that we will soon be able to choose what we dream of, and link our dreams to those of other people. Gender play in dreams may then become as common as it already is in virtual worlds.

Augmented reality could use a variety of displays, including goggles or active contact lenses. Contact lenses have the advantage of being under the eyelids so the images can be seen even when eyes are closed. During dreams, feedback from brain signals could be used to direct the selection of imagery produced in the lenses, enhancing dreams and allowing them to be linked with those of other people. This is closer than you may imagine.

Even today it is possible to pick up clues as to the images the person is seeing, and this could link into programming in an augmented reality system to generate additional appropriate imagery. We are all familiar with building external sound into dreams, and we should expect that augmented reality images could also be used by our brains. So if programs are designed well, they could use the topic detected from the sleeper as an input to search utilities, then playing appropriate media to enhance or even guide the dreamer. This would allow some element of choice before sleep, where the person could pick dreams from a menu, and have a good chance of experiencing them. Gender could be one of the choices of course.

It will be possible to link people’s dreams together, provided they are both in a dream state at the same time. Detecting signals from each one and feeding in appropriate augmented reality to each, they could be guided along converging paths until their dreams overlap. Then they would be able to interact with each other in the dreams using nerve signals to directly control the dream ‘avatar’ in the other person’s dream. Ongoing development of thought recognition should enable such dreams not only to be gently guided but also recorded.

Dreams feel more immersive and real than computer games so gender play in them may be more significant in some ways. Habitually dreaming as another gender may have long term effects on waking state too.

Voyeuristic gender play

People may choose to swap gender for a variety of reasons. Men often choose a female version of the hero in computer games, so that they can look at an attractive woman for the next 30 hours rather than a man. They are acting female for purely voyeuristic reasons, not as a means of gender experimentation. Similarly in virtual worlds, people may choose an alternative gender for the avatar simply so that they can look at them or watch them act out a role in a fantasy. This is very different from wanting to be that gender. However, someone else may do exactly the same things to try and experience being that gender. Intent is important, not the act. Intent governs the degree of association with that gender. Are they living the character, or just watching the character?

Aspirational gender

In contrast to voyeuristic play, someone may genuinely aspire to be another gender or to adopt some of its characteristics. They may want the full TG package, or may want to pick and mix from their picture of the traits on offer, TG-lite if you will. There are very many variants of this. Physically, there are lots of combinations of surgical and hormonal changes, as well as simple use of cosmetics. There are also many variations of feminised, camp or tomboyish behaviour, which may result from natural, environmental or medical use of hormones, exposure to cultural pressures or from deliberate personal choice. Pick and mix gender is illustrated in typical sissy play, where a basket of cherry-picked feminine attributes and behaviours are assembled while retaining the underlying masculinity. This falls short of the full gender change play that also happens in such worlds. The outlets in virtual worlds allow people to indulge many behaviours they associate with another gender safely, and they can do so openly or hidden as they wish. The result is a rich mixture of variations of the two standard genders.

Some people feel that they are the wrong gender and some badly enough to go through the trauma of surgical reassignment, but there are many more who would change if they could do so easily and painlessly, and probably even more who would choose to be another gender if they were able to live their life again or reincarnate. The social barriers to changing are high, as are the physical ones. But that doesn’t necessarily affect the aspiration to change gender. Technologies that allow this in part or avoiding negative social issues would cater to these latent gender changers and thus be relatively popular since they allow at least some of the frustrated aspirations to be achieved.

Environmental impact on gender - exposure to feminising chemicals

Many studies over the last decade (and even earlier) have shown endocrine disruptors (which mimic the behaviour of estrogens) in the environment causing feminisation in insects, fish, amphibians, birds, reptiles and mammals. Such chemicals come from plastics, packaging, pesticides, cleaning products and even shampoo and the linings of tin cans. In extreme cases, polluted rivers have seen 100% of male fish (Roach) becoming hermaphrodite. Effects are greater in the young. Google it for examples. You’ll find lots.

Humans are animals too of course, and although they may not have enough exposure to human endocrine disruptors in our everyday environment to cause adult men to actually change into women, again there do appear to be significant effects, especially on such things as sperm counts, breast development and testicular cancer rates. Sperm counts have fallen dramatically over the last few decades.

In the womb, effects are potentially far greater. In 2007, the Arctic Measurement and Assessment Program found twice as many girls as boys being born due to levels of chemicals in the blood of pregnant women there that were high enough to cause gender change. In Japan too, fewer boys are being born.

Surprisingly perhaps, the effects on humans have not had much study, but this is perhaps because of the potential reactions of militants in the gay and transgender communities. It is a sensitive area, but we ought to be able to discuss it properly and openly. We are using more and more chemicals in our everyday lives – more hygiene and cleaning products, more processed foods, more packaging, more plastics generally. Exposure to human endocrine disruptors is already high and may become higher if we keep brushing the issues under the carpet.

What is at stake?

If men are becoming feminised, we will gradually lose the contributions of one end of the masculinity spectrum. Gender lines have already blurred and are blurring further, and the impact  on our culture is as important as the impact on health and fertility. These problems will escalate if unborn babies and younger generations with greater vulnerability are exposed to relatively higher exposures.

It does seem that men are showing their feminine sides far more than used to be the norm. Are metrosexuals in increasing abundance because of fashion and cultural exposure, or because of chemicals changing their preferences, or a combination. Why do men cry more now? Why are more men gay and bisexual than before? Why do far more teenage boys want gender changes than before? Any one trend arises from a combination of factors, but if the overall feminisation is due in part to chemical exposure, and it probably is, then perhaps that is a problem that should be fixed. Genders are important and should be a matter of choice human culture and social make-up shouldn’t be dictated by pollution.

Why does it matter?

Male, female, inter-gender and transgender people make diverse contributions to overall society and culture. The different ways men behave and think and react and emote, or not should be valued and preserved as well as other genders and behaviours. The feminised end of the male spectrum is growing, but we should worry about losing ‘straight’, non-metrosexual masculinity. It has value too. In the gender spectrum, one end of the male part is becoming fainter while the other intensifies.

So what to do?

If cultural and chemical effects on men created pressure in opposite directions, they might cancel to some degree, but they don’t. They both create feminising pressure. Men have been under strong social and media pressure to feminise for decades. It simply isn’t fashionable to be a man today. Male behaviour is ridiculed routinely throughout the media, especially in advertising, with men portrayed as cavemen and idiots in a world of highly evolved and intelligent women. Men are encouraged to explore and show their feminine sides. The UK and US education systems have been restructured to favour the ways girls learn. Boys are punished and put down in the playground if they dare to behave as boys. Selection of participants in reality TV shows such as ‘Big Brother’, ‘I’m a Celebrity’ and ‘Come dine with me’ greatly favours feminised men to fill the male half. TV presenting is the same. Women have significantly greater legal rights than men. In the workplace, women and gay men are heavily protected and given positive discrimination at the expense of straight men. While chemical exposure is already creating biological feminising pressure, society is kicking masculinity while it’s down.

We should obviously start to limit exposure to chemicals that cause feminisation. But society should also question its attitudes and consider the long term consequences of anti-masculinity pressure. Do we really want a world with only feminised men? Masculinity deserves to be preserved too.

Symbionts

Science fiction (such as Star Trek) holds the concepts of symbionts, organisms that share bodies, where one acts as a host or carrier for the other in a symbiotic relationship, though of course it could equally be parasitic or commensalistic. This sort of thing could extend to gender too, where two distinct characters interact, share or overlap in such ways that they form a gender together. Separately they may have no gender or hold a different one, but when linked together they generate a new distinct gender.

The question arises as to how far this concept could be taken. In principle, quite far. One group could participate in a number of distinct genders depending how they combine with other groups. Three or more could combine. They could have some physical, some neural, and some virtual links. With many different ways of connecting and sharing sensations, emotions and thoughts, with many combinations of organism and indeed synthetic organisms or AIs, the idea space is huge.

Gender forcing

Some people have fantasies (or nightmares for a few too) of forced gender change. In the real world, this would be a relatively rare event (I assume that some people enslaved in the sex trade may have forced gender change, but have no idea how widespread a problem that is) but in virtual worlds, it apparently happens quite a lot.  Of course, the victim may want it to happen, in which case they would simply be enjoying no-fault recreational gender change while pushing the blame onto someone else. But it could also be genuinely unwanted. As a part of role play or a game forfeit, and temporary, it may still be accepted. If it is permanent that might be very different. In such a case, it could have more severe consequences.

Widely different degrees of reality and immersion are possible, as I have discussed already. If someone is forced into a different gender even in a virtual world and can’t revert for some reason, maybe their identity irrevocably locked to that gender, then they would simply have to get used to it, or leave that virtual world. It wouldn’t necessarily always be possible to create a new identity to escape and the social costs of leaving entirely might make the new gender the lesser of two evils. This could extend to some augmented reality applications, again with varying degrees of immersion and realism.

A closely related problem is that if someone assumes a different gender in a virtual world for a significant time, they may accumulate valued relationships that would be damaged if they were to change to their real gender, so again the costs of reverting would be unacceptable and they are effectively locked in their presented gender. Since there is so much gender play in virtual environments, I suspect this is not likely to be a major issue overall, but it still could be for particular individuals or relationships. Although less likely than in socialising virtual worlds, it is possible that employees in geographically spread virtual companies could present to some or all of their colleagues as an alternative gender than their reality, and reverting could potentially thus come at a career cost. Video and voice changing technologies will make such pretence easier and perhaps more common. Fiction has many examples of people presenting in a different gender to colleagues for professional reasons. The spread of freelancing and virtual companies makes it more likely, and the potential lock-in would follow.

So gender forcing is already here, albeit mainly virtually. The magnitude of the problems would presumably simply scale with the degree and intensity of recreational gender play, since other forcing issues would correlate highly with this too.

Empathetic gender play

Compartmentalising allows people to assume multiple parallel threads of behaviour and present different genders or gender-related traits to different groups even at the same time. The personal psychological costs and difficulty associated with this would vary between individuals but if it is easy for someone, they may do it a lot. Even without any particular desire to change, they may simply find it easier to empathise with another person by assuming their gender during the encounter. It may be such casual gender changing would happen for other reasons too.

Gender as an art form

I’ve always found it fascinating as a technologist and engineer how the first users of new technological breakthroughs are so often artists. As we mess around increasingly with genetics, it can only be a while before we see the first artistic exploration of gender creation. I wouldn’t know where to start predicting what artists will do with it, I’ve already mentioned most of the available dimensions. Part of the fun of art is the surprise when it happens. Let’s wait and see.

How many genders are there?

Most people would initially count male and female, and quickly recall others such as shemales (or ladyboys) and hermaphrodites. But there are already a lot more combinations. Assuming many different degrees of casualness, immersiveness, and commitment, virtualisation, parallelism and multi-threading of gender play, on top of many different states and combinations of physical, hormonal and psychological base, there are already hundreds of possible gender states. This number will grow markedly as we add new dimensions for experimentation. Each extra dimension would include several possible states, so the far future will certainly contain thousands of potential variations.

The future of gender is a very diverse one!

Spotify definitely isn’t the future for music. So what is?

Rant ahead, move along if you aren’t interested.

Actually, 6 months on, I tried it again. Content-wise, it is far far better than it was with a lot of stuff I wanted now available, albeit they have the same probs scanning in albums as me, with some tracks mixed up. I haven’t subscribed so cant try streaming it via my squeezebox which was my biggest gripe. Certainly might well give the free version a good play on my PC for a while and might even try again. No company is beyond redemption. Anyway, here is my original. Just bear in mind that some is now out of date.

 

 

So, I just cancelled my Spotify premium account. I gave it a good try – just over a year, so that’s over a hundred quid, and I reckon because of the problems using it I have listened to about 100 tracks over that time. Pretty poor value for me. It can be used, but is so difficult to use with my setup, I hardly ever did. And when I tried, usually the licenses had expired so it would spend ages downloading them again before it would let letting me listen. And usually several of the tracks on each playlist were no longer available. And worse still, on three occasions over that time, the whole application has gone missing off my PC spontaneously and I have had to download it afresh.

When I just want to listen to a music track, I don’t want to have to find the Spotify page, download the app again, wait ages while it installs, resyncs a few hundred tracks across all my playlists, clogging up my internet access for ages, log in again, figure out why it won’t talk my Squeezebox any more, fix the complaints by the software that my Squeezebox is logged in so I cant log in via my PC, put up with the inexplicably bad interface to the Squeezebox, wondering why the hell I can’t just use my PC version and then click a button to stream it, then take a trip to the lounge to change channel on my media system, then come back, switch off the one on playing on my PC speakers at the same time, and then figure out which of the two playlists I now have up is the right one, and then work out that the reason it isn’t playing the one I want to listen to is no longer available from Spotify, then figure out how to go back to the Squeezebox interface and find it on my hard drive from my CD collection, then play that, then wonder how I get back onto Spotify without losing the track playing, then try to find which playlist I had going…. etc etc.

Spotify does not work for me. It is better than Napster, but only on a 3/10 score is better than a 1/10 score basis. Both are total rubbish when used with a Squeezebox in another room. Part of that is the Squeezebox’s (Logitech’s) fault, part Spotify’s but if they have an agreement to work together, and claim to do so in their sales pitches, then it is both their faults. My Squeezebox is wonderful when it works. When!

So that’s why I cancelled. I clicked the ‘don’t use enough’ button on their form, but couldn’t click all the others that applied because they only permit one option. I didn’t use it enough because it is total crap. The only reason I didn’t cancel earlier is because I kept forgetting to.

Spotify is fine on just my PC, but then I don’t need the streaming, so the free one is fine, I just turn down my speakers when the adds come on.

OK, let’s move on from Spotify and my darned Squeezebox. I like listening to music, when it’s easy. When I used CDs I listened frequently. Then I got my first MP3 player, and much later various iphones. I have never used any of them more than a few minutes at a time. Having all your music on an easy button click means that with my hamster-like attention span, I hit a new track every few seconds and my enthusiasm quickly burns out. A kid in a sweet shop soon gets sick. And anyway, my iPhone battery seems to be empty every time I pick it up. Another piece of crap but that’s Apple for you.

I use my PC to store all my CD music, and rarely use them now. One problem I have and I am sure must share with others is that on iTunes some tracks get misnamed or worse still, just come over as unknown. I made the huge mistake once of letting iTunes reorganise my library and everything got so screwed up I had to scan in all my CDs again. I own about 20 tracks I bought from Amazon or Napster. They are on my PC, but are always hard to find when I use the media server or Squeezebox because the interfaces are bad. So even there, with music I own, on my own PC, listening is OK to a point, but still has loads of problems. I am listening to a playlist right now and picked ‘play all’, but I still have to go into the Logitech screen every track to make it play the next one instead of  letting it repeat the same track endlessly. It doesn’t work! It isn’t my fault. I am reasonably smart and have 30 years IT experience. If I can’t use it, it is designed badly. Simple as that.

I have a new Freesat system with a hard drive, and am told I can use that to store and play my music. I’ll reserve judgement on that till I try it. I haven’t plugged it in yet.

The future

So how do I get music? I don’t want to use a personal MP3 player all the time. What I really want is to be able to just see a big swathe of album covers, preferably virtual ones hanging in space in front of me, and touch one, then pick the track, or do all that with a playlist. Or speak a voice command, or use a simple search tool by .

When I play it, I want to watch the music video, and I want music made for full 7.1 surround, not bloody stereo. I want to feel I am there in the studio or concert. I want full sensory, full immersion music, with every sense stimulated in synch.

I don’t mind paying. I have never listened to a track I don’t have the legal right to listen to. That never has been an issue. I have bought a lot of what turned out to be rubbish and I’d like a refund please. Same with all the many dupes I own. Can I sell them please? Also, can I give in all my vinyl LPs and get lifetime licenses to digital version please? But I won’t hold my breath on that.

I want to pay a subscription to something a bit like Spotify, but a more professional one that sort of works. I want access to all the other music. And when I spend time making  a playlist, I don’t want to find 20% of the tracks won’t play next time I access it. I want it to integrate seamlessly with my owned tracks, in the correct sense of the word, not exaggerated sales hype. And I want to be able to point at any set of speakers in my house, or anywhere else for that matter and stream it from there, now. I don’t want to fight battles with software or have to log in to anything, or to update software, or re-establish internet connections, or be told I cant use it in the lounge because I am logged on in the office.

The music industry insists on being paid. But by doing so in such clumsy and badly implemented ways, they have destroyed any pleasure from listening to music and alienated countless customers. I tried to buy CDs, but Apple can’t copy them properly onto my PC. My PC can’t stream them reliably through my Squeezebox because of Microsoft and Logitech. No music subscription service I can access on the Squeezebox is any good at all. So I’ll keep the money in my bank account. I listen to music so much less now because it’s such a pain, so the novelty doesn’t wear off any more, so I have enough. A small loss to the global music industry perhaps, but many others aren’t willing to pay at all so I am part of the group they needed to keep on board. For 20 years they have been trying to get a working business model. This isn’t it.

Spotify aimed at the future, and missed.

Fairy stories as a guide to the future?

OK, clutching at straws for a topic this morning, but here goes. Arthur C. Clarke said that sufficiently advanced technology is indistinguishable from magic and I agree. Engineers often derive inspiration from science fiction (and vice versa), but the magic in fairy stories might be a rich source of ideas too. If we look to fairy stories to see the sorts of things people do with magic, then we should see some markets for real advanced technology. Not all of them will be feasible, but some will. It may not be a very standard futures technique, but it should work. We won’t know if we don’t try. There is a pretty standard formula now for producing ideas and techniques in science fiction and computer games. Just mix together some nice potions such as synthetic biology, nanotechnology, genetic modification, artificial intelligence, neurotechnology, virtual, quantum and so on, and you can’t go far wrong, you will end up with all the magic you can imagine. Fairy stories are a bit pre-technology, but maybe we’ll see some ideas.

Let’s start with love potions, evil kisses, poisoned needles and the like. These are included in many stories as tricks that conceal means to control others, spy on them, make them do things or think things. Could that be done? Yes, probably. I wrote about hacking into people’s brains and remote controlling them in my ‘Zombies are coming’ piece, and about some related concepts in my pieces on immortality via direct links to the brain. It essentially uses bacteria to infiltrate the other person’s body via hand contact, a simple kiss, or eating something, and once introduced, the bacteria reproduce and synthesise the components that then connect to nerves in the brain and form a remote control channel. So you could create anything in their mind – sensations, memories, ideas, anything. You could make them believe anything, love anyone, or just hack into their mind to see what they are thinking, any of those sorts of things. Sure, it would be difficult, but it will be feasible one day.

Mind reading is already with us to some degree. Some computer games can be controlled by thought, wheelchairs for the disabled. Scientists can even work out what videos someone is thinking about by comparing the electrical signal they emit to those gathered when they were actually viewing  a selection of videos earlier.

How about preserving someone? Like sleeping beauty. Well, hibernation research has been going on for ages already, and one day that will come up with the goods too. It probably won’t involve spinning wheels, but an injection of some sort is quite likely.

Invisibility is a common occurrence in fairy stories too, and in real life, scientists can make small objects almost invisible too, using special fabrics that bend light or cameras coupled to light emitting fabrics. So far they only work from one direction, and some only work in small colour ranges, but we’re getting there.

Levitation can be done with magnets and superconductivity. Being in two places at once, well I guess that is called Skype.

I am struggling to think of stuff in fairy stories that can’t already be done in the lab or that we at least have a good idea how to do it. Ah yes, frogs that turn into princes. Well, outside of computer games or virtual worlds, it would be difficult, but as augmented reality becomes everyday stuff, we”’ see lots of people using weird avatars, and who knows, some princes with a sense of fun might well choose to be frogs.

The magic wand would also feature well in augmented reality but in the real world would have little real application except as a simple interface to start other processes.

Actually though, I am going to stop here. Fairy stories are a rich source of ideas for technologies we already have or already know about. A part record of the scope of imagination in days gone by. They maybe aren’t so good as a future tool after all. Maybe we need more science fiction writers to do fairy stories before that will be fixed.

More uses for 3d printing

3D printers are growing in popularity, with a wide range in price from domestic models to high-end industrial printers. The field is already over-hyped, but there is still room for even more, so here we go.

Restoration

3D printing is a good solution for production of items in one-off or small run quantity, so restoration is one field that will particularly benefit. If a component of a machine is damaged or missing, it can be replaced, if a piece has been broken off an ornament, a 3D scan of the remaining piece could be compared with how it should be and 3D patches designed and printed to restore the full object.

Creativity & Crafts

Creativity too will benefit. Especially with assistance from clever software, many people will find that what they thought was their small streak of creativity is actually not that small at all, and will be encouraged to create. The amateur art world can be expected to expand greatly, both in virtual art and physical sculpture. We will see a new renaissance, especially in sculpture and crafts, but also in imaginative hybrid virtual-physical arts. Physical objects may be printed or remain virtual, displayed in augmented reality perhaps. Some of these will be scalable, with tiny versions made on home 3D printers. People may use these test prints to refine their works, and possibly then have larger ones produced on more expensive printers owned by clubs or businesses. They could print it using the 3D printing firm down the road, or just upload the design to a web-based producer for printing and home delivery later in the week.

Fashion will benefit from 3D printing too, with accessories designed or downloaded and printed on demand. A customer may not want to design their own accessories fully, but may start with a choice of template of some sort that they customise to taste, so that their accessories are still personalised but don’t need to much involvement of time and effort.

Could printed miniatures become as important as photos?

People take a lot of photos and videos, and they are a key tool in social networking as well as capturing memories. If 3D scans or photos are taken, and miniature physical models printed, they might have a greater social and personal value even than photos.

Micro-robotics and espionage

3D printing is capable of making lots of intricate parts that would be hard to manufacture by any other means, so should be appropriate for some of the parts useful in making small robots, such as tiny insects that can fly into properties undetected.

Internal printing

Conventional 3D printers, if there can be such a thing so early in their development, use line of sight to make objects by building them in thin layers. Although this allows elaborate structures to be made, it doesn’t allow everything, and there are some structures or objects that would be more easily made if it were possible to print internally. Although lasers would be of little use in opaque objects, x-rays might work fine in some circumstances. This would allow retro-fitting too.

Cancer treatment

If x-ray or printing can be made to work, then it may be possible to build heating circuits inside cancers, and then inductive power supplies could burn away the tumours. Alternatively, smart circuits could be implanted to activate encapsulated drugs when they arrive at the scene.

This would require a one-off exposure to x-rays, but not necessarily similarly damaging levels to those used in radiotherapy.

Direct brain-machine links

Looking further ahead, internal printing of circuits or electronic components inside the brain will be a superb means to do interfacing between man and machine. X-rays can in principle be focused to 1nm, easily fine enough resolution to make contacts to specific brain regions. Obviously x-rays are not something that people would want to be exposed to frequently, but many people would volunteer  (e.g. I would) to have some circuits implanted at least for R&D purposes, since greater insights into how the brain does stuff will accelerate greatly the development of biomimetic AI. But if those circuits were able to link parts of the brain to the web for fast thought based access to search, processing, or sensory enhancement, I’d be fighting millions of transhumanists to get to the front of the long queue.
