3D printable guns are here to stay, but we need to ban magnets from flights too.

It’s interesting watching new technologies emerge. Someone has a bright idea, it gets hyped a bit, then someone counter-hypes a nightmare scenario and everyone panics. Then experts queue up to say why it can’t be done, then someone does it, then more panic, then knee-jerk legislation, then eventually the technology becomes part of everyday life.

I was once dismissed by our best radio experts when I suggested making cellphone masts like the ones you see on every high building today. I recall being taught that you couldn’t possibly ever get more than 19.2kbits/s down a phone line. I got heavily marked down in an appraisal for my obvious stupidity suggesting that mobile phones could include video cameras. I am well used to being told something is impossible, but if I can see how to make it work, I don’t care, I believe it anyway. My personal mantra is ‘just occasionally, everyone else IS wrong’. I am an engineer. Some engineers might not know how to do something, but others sometimes can.

When the printable gun was suggested (not by me this time!) I accepted it as an inevitable part of the future immediately. I then listened as experts argued that it could never survive the forces. But guess what? A gun doesn’t have to survive. It just needs to work once, then you use a fresh one. The first prototypes only worked for a few bullets before breaking. The Liberator was made to work just once. Missiles are like that. They fire once, only once. So you bring a few to the battle.

The recently uploaded blueprint for the Liberator printable gun has been taken offline after 100,000 copies were downloaded, so it will be about as hard to find as embarrassing pictures of any celebrity. There will be innovations, refinements, improvements, then we will see them in use by hobbyists and criminals alike.

But there are loads of ways to skin a cat, allegedly. A gun’s job is to quickly accelerate a small mass up to a high speed in a short distance. Using explosives in a bullet held in a printable lump of plastic clearly does the job on a one-shot basis, but you still need a bullet and they don’t sell them in Tesco’s. So why do it that way?

A Gauss Rifle is a science toy that can fire a ball-bearing across your living room. You can make one in 5 minutes using nothing more than sticky tape, a ruler and some neodymium magnets. Here’s a nice example of the toy version using simple steel balls:

http://scitoys.com/scitoys/scitoys/magnets/gauss.html

The concept is very well known, though a bit harder to Google now because so many computer games have used the same name for imaginary weapons. In an easily adapted version, where the steel balls are replaced by neodymium magnets held in place in alternately attracting and repelling polarities, when the first magnet is released, it is pulled by strong magnetic force to the second one, hitting it quite fast, and conveying all that energy to the next stage magnet, which is then pushed away from the one repelling it towards the one attracting it, so accumulating lots of energy. The energy accumulates over several stages, optimally harnessing the full repulsive and attractive forces available from the strong magnets. Too many stages result in the magnets shattering, but with care, four stages with simple steel balls can be used reasonably safely as a toy.

Some sites explain that if you position the magnets accurately with the poles oriented right, you can get it to make a small hole in a wall. I imagine you could design and print a gauss rifle jig with very high precision, far better than you could do with tape and your fingers, that would hold the magnets in the right locations and polarity orientations.  Then just put your magnets in and it is ready. Neodymium magnets are easily available in various sizes at low cost and the energy of the final ball is several times as high as the first one. With the larger magnets, the magnetic forces are extremely high so the energy accumulated would also be high. A sharp plastic dart housing the last ball would make quite a dangerous device. A Gauss rifle might lack the force of a conventional gun, but it could still be quite powerful. If I was in charge of airport security, I’d already be banning magnets from flights.

I really don’t see how you could stop someone making this sort of thing, or plastic crossbows or fancy plastic jigs with stored energy in springs that can be primed in an aircraft toilet that fire things in imaginative ways. There are zillions of ways to accelerate something, some of which can be done in cascades that only generate tolerable forces at any particular point so could easily work with printable materials. The current focus on firearms misses the point. You don’t have to transfer all the energy to a projectile in one short high pressure burst, you can accumulate it in stages. Focusing security controls on explosives-based systems will leave us vulnerable.

3D printable weapons are here to stay, but for criminals and terrorists, bullets with explosives in might soon be obsolete.

Killing machines

There is rising concern about machines such as drones and battlefield robots that could soon be given the decision on whether to kill someone. Since I wrote this and first posted it a couple of weeks ago, the UN has put out their thoughts as the DM writes today:

http://www.dailymail.co.uk/news/article-2318713/U-N-report-warns-killer-robots-power-destroy-human-life.html 

At the moment, drones and robots are essentially just remote controlled devices and a human makes the important decisions. In the sense that a human uses them to dispense death from a distance, they aren’t all that different from a spear or a rifle apart from scale of destruction and the distance from which death can be dealt. Without consciousness, a missile is no different from a spear or bullet, nor is a remote controlled machine that it is launched from. It is the act of hitting the fire button that is most significant, but proximity is important too. If an operator is thousands of miles away and isn’t physically threatened, or perhaps has never even met people from the target population, other ethical issues start emerging. But those are ethical issues for the people, not the machine.

Adding artificial intelligence to let a machine to decide whether a human is to be killed or not isn’t difficult per se. If you don’t care about killing innocent people, it is pretty easy. It is only made difficult because civilised countries value human lives, and because they distinguish between combatants and civilians.

Personally, I don’t fully understand the distinction between combatants and soldiers. In wars, often combatants have no real choice but to fight or are conscripted, and they are usually told what to do, often by civilian politicians hiding in far away bunkers, with strong penalties for disobeying. If a country goes to war, on the basis of a democratic mandate, then surely everyone in the electorate is guilty, even pacifists, who accept the benefits of living in the host country but would prefer to avoid the costs. Children are the only innocents.

In my analysis, soldiers in a democratic country are public sector employees like any other, just doing a job on behalf of the electorate. But that depends to some degree on them keeping their personal integrity and human judgement. The many military who take pride in following orders could be thought of as being dehumanised and reduced to killing machines. Many would actually be proud to be thought of as killing machines. A soldier like that, who merely follow orders, deliberately abdicates human responsibility. Having access to the capability for good judgement, but refusing to use it, they reduce themselves to a lower moral level than a drone. At least a drone doesn’t know what it is doing.

On the other hand, disobeying a direct order may save soothe issues of conscience but invoke huge personal costs, anything from shaming and peer disapproval to execution. Balancing that is a personal matter, but it is the act of balancing it that is important, not necessarily the outcome. Giving some thought to the matter and wrestling at least a bit with conscience before doing it makes all the difference. That is something a drone can’t yet do.

So even at the start, the difference between a drone and at least some soldiers is not always as big as we might want it to be, for other soldiers it is huge. A killing machine is competing against a grey scale of judgement and morality, not a black and white equation. In those circumstances, in a military that highly values following orders, human judgement is already no longer an essential requirement at the front line. In that case, the leaders might set the drones into combat with a defined objective, the human decision already taken by them, the local judgement of who or what to kill assigned to adaptive AI, algorithms and sensor readings. For a military such as that, drones are no different to soldiers who do what they’re told.

However, if the distinction between combatant and civilian is required, then someone has to decide the relative value of different classes of lives. Then they either have to teach it to the machines so they can make the decision locally, or the costs of potential collateral damage from just killing anyone can be put into the equations at head office. Or thirdly, and most likely in practice, a compromise can be found where some judgement is made in advance and some locally. Finally, it is even possible for killing machines to make decisions on some easier cases and refer difficult ones to remote operators.

We live in an electronic age, with face recognition, friend or foe electronic ID, web searches, social networks, location and diaries, mobile phone signals and lots of other clues that might give some knowledge of a target and potential casualties. How important is it to kill or protect this particular individual or group, or take that particular objective? How many innocent lives are acceptable cost, and from which groups – how many babies, kids, adults, old people? Should physical attractiveness or the victim’s professions be considered? What about race or religion, or nationality, or sexuality, or anything else that could possibly be found out about the target before killing them? How much should people’s personal value be considered, or should everyone be treated equal at point of potential death? These are tough questions, but the means of getting hold of the date are improving fast and we will be forced to answer them. By the time truly intelligent drones will be capable of making human-like decisions, they may well know who they are killing.

In some ways this far future with a smart or even conscious drone or robot making informed decisions before killing people isn’t as scary as the time between now and then. Terminator and Robocop may be nightmare scenarios, but at least in those there is clarity of which one is the enemy. Machines don’t yet have anywhere near that capability. However, if an objective is considered valuable, military leaders could already set a machine to kill people even when there is little certainty about the role or identity of the victims. They may put in some algorithms and crude AI to improve performance or reduce errors, but the algorithmic uncertainty and callous uncaring dispatch of potentially innocent people is very worrying.

Increasing desperation could be expected to lower barriers to use. So could a lower regard for the value of human life, and often in tribal conflicts people don’t consider the lives of the opposition to have a very high value. This is especially true in terrorism, where the objective is often to kill innocent people. It might not matter that the drone doesn’t know who it is killing, as long as it might be killing the right target as part of the mix. I think it is reasonable to expect a lot of battlefield use and certainly terrorist use of semi-smart robots and drones that kill relatively indiscriminatingly. Even when truly smart machines arrive, they might be set to malicious goals.

Then there is the possibility of rogue drones and robots. The Terminator/Robocop scenario. If machines are allowed to make their own decisions and then to kill, can we be certain that the safeguards are in place that they can always be safely deactivated? Could they be hacked? Hijacked? Sabotaged by having their fail-safes and shut-offs deactivated? Have their ‘minds’ corrupted? As an engineer, I’d say these are realistic concerns.

All in all, it is a good thing that concern is rising and we are seeing more debate. It is late, but not too late, to make good progress to limit and control the future damage killing machines might do. Not just directly in loss of innocent life, but to our fundamental humanity as armies get increasingly used to delegating responsibility to machines to deal with a remote dehumanised threat. Drones and robots are not the end of warfare technology, there are far scarier things coming later. It is time to get a grip before it is too late.

When people fought with sticks and stones, at least they were personally involved. We must never allow personal involvement to disappear from the act of killing someone.

22nd century speculative sci-fi super-chemistry

Helium is unreactive, because it has two electrons in a shell that holds two electrons. It doesn’t want any more, and doesn’t want to lose any.

Well, stuff that! There could (and should) be a physical state where it shares those electrons with another atom. On checking the web, it turns out that in plasma conditions it can exist (excimer), though it isn’t much use in ordinary everyday life.

OK, so helium can be forced eventually to play, even if not especially nicely. What about carbon? Carbon has 4 electrons in its outer shell and wants 8 so is happy to form 4 covalent bonds with other atoms. So it is much nicer to play with than helium. However…..

Suppose, just suppose, that having shared its outer electrons, we can do some sort of sub-chemistry with its inner ones. OK, I know that isn’t quite the norm. What sort of thing would we have to do to make atoms engage in some sort of super-chemistry with their inner electron shells? Stupid question, possibly, but I am a futurologist, not a historian, (or a chemist) and know that old barriers don’t always last.

The reason I am interested in is that I am brainstorming new kinds of carbon materials, just for fun. We already have several allotropes with some great and useful properties. Diamond is quite strong, graphene is stronger, but a bit thin, so wouldn’t it be nice to have a 3D material like diamond but which has better bonds? I was drawing some pretty pics of graphene and noticed an optical illusion appearing, where it starts to look cubic, except that some of the lines are missing. Each point in a cubic array has 6 links, or bonds, not 4. Diamond has 4 , but if a super-diamond had 6, it might be better still.

So, we can get 4 carbon bonds with the outer electrons easily enough, but IF we could somehow get the two inner ones to play in some sort of virtual excimer as well … what should happen is that we could make a cubic form of carbon. Which, idly speculating, should exist as a sort of solid plasma. At very high temperatures, far beyond what diamond could cope with. Being able to withstand high forces at high temperatures, and conducting electricity, it would be possible to build one hell of a plasma rifle with it. Or an electron pipe that could carry a billion times higher data rates than optical fibre. http://thisshouldbeok.wordpress.com/2011/04/09/electron-pipe/

We can’t do it yet, but just for the record, you saw it here first.

Could graphene foam be a future Helium substitute?

I just did a back-of-the-envelope calculation to work out what size of sphere containing a vacuum would give the same average density as helium at room temperature, if the sphere is made of graphene, the new one-size-does-everthing-you-can-imagine wonder material.

Why? Well, the Yanks have just prototyped a big airship and it uses helium for buoyancy. http://www.dailymail.co.uk/sciencetech/article-2257201/The-astonishing-Aeroscraft–new-type-rigid-airship-thats-set-revolutionise-haulage-tourism–warfare.html

Helium weighs 0.164kg per cubic metre. Graphene sheet weighs only 0.77mg per square metre. Mind you, the data source was Wikipedia so don’t start a business based on this without checking! If you could make a sphere out of a single layer of graphene, and have a vacuum inside (graphene is allegedly impervious to gas) it would become less dense than helium at sizes above 0.014mm. Wow! That’s very small. I expected ping pong ball sizes when I started and knew that would never work because large thin spheres would be likely to collapse. 14 micron spheres are too small to see with the naked eye, not much bigger than skin cells, maybe they would work OK.

Confession time now. I have no idea whether a single layer of graphene is absolutely impervious to gas, it says so on some websites but it says a lot of things on some websites that are total nonsense.

The obvious downside even if it could work is that graphene is still very expensive, but everything is when is starts off. Imagine how much you could sell a plastic cup for to an Egyptian Pharaoh.

Helium is an endangered resource. We use it for party balloons and then it goes into the atmosphere and from there leaks into space. It is hard to replace, at least for the next few decades. If we could use common elements like carbon as a substitute that would be good news. Getting the cost of production down is just engineering and people are good at that when there is an incentive.

So in the future, maybe we could fill party balloons and blimps with graphene foam. You could make huge airships happily with it, that don’t need helium of hydrogen. 

Tiny particles that size readily behave as a fluid and can easily be pumped. You could make lighter-than-air building materials for ultra-tall skyscrapers, launch platforms, floating Avatar-style sky islands and so on.

You could also make small clusters of them to carry tiny payloads for espionage or terrorism. Floating invisibly tiny particles of clever electronics around has good and bad uses. You could distribute explosives with floating particles that congeal into whatever shape you want on whatever target you want using self-organisation and liberal use of EM fields. I don’t even have that sort of stuff on Halo. I’d better stop now before I start laughing evilly and muttering about taking over the world.

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?

The future of tribalism

Introduction

I often cite tribalism as a powerful force in determining how technology plays out. Tribalism conveys obvious evolutionary advantages and has become deeply ingrained in human nature. Even when there weren’t many humans, they used to fight each other for control of resources, and for other kinds of power too. Those that were successful are our ancestors; their genes survived. As individuals in a difficult world, people may not have survived well. In groups they did, and the best groups survived best. It’s very useful to have others who will help protect you and your family’s interests.

Tribalism has a dark side of course. I lived in Belfast throughout ‘the troubles’,  (a mixed-motivation tribal conflict of Irish and catholic v British and protestant, and people not fitting neatly into that often found themselves disliked by both sides. Recently, as immigration has increased, it is sadly evolving into racism.) It is holding Africa back, and the Middle East, and the Far East. In fact, most of the world suffers some significant manifestation of tribal conflict.

Clearly tribal forces can bring potential benefits and potential damage, and they need to be managed, carefully.

If the good side of tribalism is fostered, it brings benefits. In Europe, the EU’s greatest legacy has been its moderation of tribal conflict by harnessing combined efforts to common goals – we all want peace and prosperity. In the USA, this approach has evolved into a strong patriotic feeling that greatly helps maintain the economy, and peace and security. Regional tribalism seems to be useful.

I think though that the right balance is hard to achieve. Too much, wars happen; too little, things fall apart. Misdirected and mismanaged, other problems occur – rioting, abuse, exploitation, a long list.

The redefining of ‘racism’

In a modern world where there is no need to compete for basic existence, we can and should put ethnic tribalism aside – the many different races may look different but are barely distinguishable genetically and modern races are biologically irrelevant. The abuse of people just because they have a different skin colour is wrong, and thankfully is gradually becoming a thing of the past. Most decent people would want to keep it there. Nobody wants to be accused of being a racist, which has become one of the worst insults that can be thrown at someone. I’d think that was a good thing if the meaning of ‘racist’ stayed the same.

However, the meaning of racism has evolved, especially in the last decade, from being just about skin colour, to include any distinction based on skin colour, geography of residence or birth, religion, or even lifestyle choice. That to me is going too far. I certainly want  people to live peacefully side by side as far as possible, but I don’t see that that means all cultures and attitudes have to be considered equal. They aren’t. If for example, a national or religious group mistreats women or children,  I don’t respect that. It is wrong to mistreat women and children. We should be free to say so. Discrimination against wrong ideologies and attitudes is appropriate and is not racist, even if the incidence in a particular race is higher than in another. We must clearly separate race issues from ideological, political and behavioural ones. However, there are frequent attempts to blur them instead with more and more groups trying to wave a race card to get extra political leverage. Sadly, as other things are added under the race banner, its original meaning is diluted, and its value will inevitably fall as a consequence. When everything is classed as racist, nobody will care any more and it will have lost its force.

Racism has also expanded to include geographic region rather than race. People certainly are tribal about where they live, but that doesn’t make them racist. Nationalism and patriotism are not at all the same as racism. It isn’t just the UK as a whole  that is seeing increasing geographic tribal forces and desire to leave the EU. Within the UK, Scotland, Wales, Northern Ireland, Yorkshire, London, and Cornwall have all been looking at the issue of their own separation at some point, recognising their own tribal distinctions. Catalonia too. Geographic tribalism is just one dimension and apart from Rotherham Council and David Cameron, most of us think it is OK. So why are there already problems with making remarks about people who live in different areas, belong to the other tribes? If you want to say Northerners are friendly, I don’t think that is a racist comment, even though it clearly implies that others are less so. But why is it racist to say something about the Scots or Irish or Welsh? Why is it fine to have regional tribes such as the EU, and ones for some sub-areas, but not for others? It makes no sense. None.

The Politically Correct path to 1984 hell

With political correctness, it’s seems as though you get given an even bigger halo if you add even more factors to your list of things you shouldn’t discriminate against. Anti-racism became a general desire for protection of minorities, and has since grown up to become a generic anti-tribalism, and the less tribal you are, the holier. But where does the political correctness road end? It ends only when there is no right or wrong, and you aren’t allowed to say something is right or wrong without being punished. To stop before that is just being arbitrary. Criminals are just another minority, and research is even finding genetic biases for certain criminal behaviours. So if good sense doesn’t reassert itself over political correctness at some point, in the far future, if you want to mug and steal, take drugs, torture your animals to death for dinner, oppress your multiple wives and slaves, and sexually abuse your kids, that would all be fine, since all cultures and creeds must be treated equally. If you disagree, you are just a racist.

To me the biggest problem is the inclusion of religion, making it ‘racist’ and hate crime to criticise other religions. It makes absolutely no sense to me. Religion is about beliefs and people can believe in almost anything. If someone wants to believe something, they should be totally free to do so, and I should be free to say whatever I want about their beliefs. If someone says they genuinely believe 2+2=5, that’s fine with me, but I should be allowed to say they are an idiot and treat them accordingly. I won’t in case it’s a hate crime, but I should be allowed to. If they believe in Dawkins’ Great Spaghetti Monster, or are Jedi, still fine with me, but don’t expect me to support any privileges for them for doing so. Sadly, we’re already half way down that path.

(While we’re on the subject of hate crime, calling someone names just isn’t equivalent to physically assaulting someone or bypassing them for promotion. Growing up in Belfast, I frequently got called every name going with often significant hatred behind it, but I’d been taught the old rhyme about sticks and stones, and the names never did me any harm beyond brief annoyance. Misplaced homophobic abuse I received when I rented a house with some gays just made me laugh – it is hard to take abuse seriously when it comes from such pathetic abusers. Listening to the news the last few months, it seems name calling has become a career-destroying offence, certainly a far worse crime than expenses fraud, deliberate deception, murdering old people or ignoring paedophilia.)

Trying to bury tribalism

PC-devoted liberals in Europe seem to have been trying to bury tribalism completely, to pretend it doesn’t exist, or try to regulate it out of existence as if it is an evil that can be purged. It seems more and more tribal dimensions are to be covered in their extended hate crime category, wrapping it up with race as far as possible. In the UK, this has now reached extremes. The news this week that Rotherham council removed children from their foster parents because they belonged to the UK Independence Party is a good example. They accused the UKIP of racism because they favour focusing efforts on UK interests rather than those outside the UK. So now we have one tribe, Labour, using the power of office, and using innocent children as their weapon of convenience, to force their own tribal views onto members of another tribe, UKIP, with the excuse that that tribe has tribal views.

The real irony of the Rotherham case is that Liberals (and many would include Cameron in that category) are insulting a tribe just because they want to stay a distinct (geographically defined) tribe, i.e. the UK, while simultaneously trying every trick possible to force us all into tribal membership in a European Superstate. So, ‘it is racist if you want to be in your tribe but you must join our tribe and that isn’t racist’.

The lack of proper apologies from those responsible and Cameron saying that he didn’t mean that UKIP are all closet racists, that not all are – it doesn’t look good for the future of freedom of thought, does it?

1984

It is at Rotherham that we really must draw the line. If we don’t reject this style of thinking, if political correctness is to gradually outlaw all of the tribal dimensions, then we may find any political viewpoint except the current state-sanctioned line is labelled as racist. If we’re lucky, we may get an authorised opposition. Then we’ll all be locked in a 1984 hell, treated as cloned slaves belonging to the State.

If that happened, then we’d secretly be conspiring revolution, because people are tribal and most will not behave like that willingly. Then, new technologies will be used that can restrict the ease of conspiring by using more and more surveillance, making it deeper and more personal, eventually thought monitoring and thought control. My evolution chart for the future of humans includes homo zombius around 2075. It is technologically feasible. And socially. And politically.

In the short term, using all too familiar justifications such as crime control, anti-terrorism, and controlling media standards – while extending the rules to social media, government is grabbing more power to control the information we can get hold of, the messages we can spread, and access to technology. Apple recently and unhelpfully patented a system to allow police to turn off smartphones in an area. Government has tried a few times now to introduce screening of every use of communication such as web site access lists, all our messages, all social media and so on. Such measures often get blocked, and then reintroduced, again and again, just like ID cards, or the speed cameras that were meant to be disappearing but are breeding like rabbits. The government says what they want us to hear very loudly, and generally retracts it a week later very quietly. Eventually, the extra surveillance measures will stick. Individually, these can all be explained as sensible approaches to big problems. But they won’t stay in their boxes long. They all give extra power to future authorities, and some of those authorities will have staff like Rotherham social service chiefs.

But tribalism can’t be eliminated

Tribalism is a powerful force in human nature and reasserts itself here and there, from time to time. To deny it or to try to outlaw it is to invite at least as many problems as indulging it. And they will often be harder to deal with than the simple results of tribal conflicts that are usually open to negotiation. There are very many dimensions on which tribal forces can act, thanks to the richness of human culture. Race, gender, age, geography of birth and of residence, political ideology, religious creed, football club support, celebrity following, the list goes on and on. Government can try to block them, but like a river, it can’t stop it, only divert it or dam it for a short time before it spills over.

Football was one of the great diversions of course. Instead of tribes going to war with each other and fields full of corpses, football teams could kick a ball around a while and let of the same tribal pressures. But football is now a major front in the battle against racism, actual skin-colour style racism. I don’t know what that will cause. Will the racism go underground if it doesn’t have an outlet on the terraces, maybe increase BNP support? Who knows? I don’t. Did somehow those involved survive the forces that cured the rest of society of racism, or is it just that too much is being made of the small remnants that survived, perhaps rekindling flames by trying to blow them out? What will be the next phase of it? In Glasgow, the sectarian conflict had an outlet in Rangers v Celtic. Will sectarianism be the next front in the anti-tribalism war? Will that force pressure underground?

Tribal battles are brewing on many other fronts too.

Old people are becoming much more expensive, just as younger people are being fleeced. Those young people will find those older people voting themselves better pensions and health care, which they know won’t be available to those having to pay for them. Intergenerational conflicts are inevitable. The private v public sector battle hasn’t gone away, and will resurface many times over the next decade. The Europhile v Eurosceptic battles are just getting organised. Gay rights issues don’t stop with gay marriage and gender will bring entirely new problems in a decade or two as new genders come on the scene. Body augmentation, mental augmentation and customisation, even artificial intelligence are all fronts for future tribal conflicts.

Even fashion and pop music invoke tribalism. Every school-kid knows the feeling of being verbally or even physically abused because they have a different dress style or make-up style than some other group. Or because they prefer one artist over another. How long before there are demands to label these as hate crimes too? Or is that already history.

Tribalism will never go away. Human culture will continue to evolve, and whole new areas will often be created where tribalism can and will appear. Political correctness can try hard to keep up, but tribalism will outlive it by millennia.

 

The future of time travel: cheat

Time travel comes up frequently in science fiction, and some physicists think it might be theoretically possible, to some degree, within major constraints, at vast expense, between times that are in different universes. Frankly, my physics is rusty and I don’t have any useful contribution to make on how we might do physical time travel, nor on its potential. However, intelligence available to us to figure the full physics out will accelerate dramatically thanks to the artificial intelligence positive feedback loop (smarter machines can build even smarter ones even faster)  and some time later this century we will definitely work out once and for all whether it is doable in real life and how to do it. And we’ll know why we never meet time tourists. If it can be done and done reasonable economically and safely, then it will just be a matter of time to build it after that.

Well, stuff that! Not interested in waiting! If the laws of physics make it so hard that it may never happen and certainly not till at least towards the end of this century, even if it is possible, then let’s bypass the laws of physics. Engineers do that all the time. If you are faced with an infinitely tall impenetrable barrier so you can’t go over it or through it, then check whether the barrier is also very wide, because there may well be an easy route past the barrier that doesn’t require you to go that way. I can’t walk over tall buildings, but I still haven’t found one I couldn’t walk past on the street. There is usually a way past barriers.

And with time travel, that turns out to be the case. There is an easy route past. Physics only controls the physical world. Although physics certain governs the technologies we use to create cyberspace, it doesn’t really limit what you can do in cyberspace any more than in a dream, a costume drama, or a memory.

Cyberspace takes many forms, it is’t homogeneous or even continuous. It has many dimensions. It can be quite alien. But in some areas, such as websites, archives are kept and you can look at how a site was in the past. Extend that to social networking and a problem immediately appears. How can you communicate or interact with someone if the site you are on is just an historical snapshot and isn’t live? How could you go back and actually chat to someone or play a game against them?

The solution to this problem is a tricky technological one but it is entirely  possible, and it won’t violate any physics. If you want to go back in time and interact with people as they were, then all you need is to have an archive of those people. Difficult, but possible. In cyberspace.

Around 2050, we should be starting to do direct brain links, at least in the lab and maybe a bit further. Not just connections to the optic nerve or inner ear, or chips to control wheelchairs, we already have that. And we already have basic thought recognition. By 2050 we will be starting to do full links, that allow thoughts to pass both ways between man and machine, so that the machine world is effectively an extension of your brain.

As people’s thoughts, memories and even sensations become more cyberspace based, as they will, the physical body will become less relevant. (Some of my previous blogs have considered the implication of this for immortality). Once stuff is in the IT world, it can be copied, and backed up. That gives us the potential to make recordings of people’s entire lives, and capable of effectively replicating them at will. Today we have web archives that try to do that with web sites so you can access material on older versions of them. Tomorrow we’ll also be able to include people in that. Virtually replicating the buildings and other stuff would be pretty trivial by comparison.

In that world, it will be possible for your mind, which is itself an almost entirely online entity, to interact with historic populations, essentially to time travel. Right back to the date when they were started being backed up, some time after 2050. The people they would be dealing with would be the same actual people that existed then, exactly as they were, perfect copies. They would behave and respond exactly the same. So you could use this technique to time travel back to 2050 at the very best but no earlier. And for a proper experience it would be much later, say 2100.

And then it starts to get interesting. In an electronic timeline such as that, the interactions you have with those people in the last would have two options. They could be just time tourism  or social research, or other archaeology, which has no lasting effect, and any traces of your trip would vanish when you leave. Or they could be more effectual. The interactions you have when you visit could ripple all the way back through the timeline to your ‘present?’, or future? or was it the past when you were present in the future? (it is really hard to choose the right words tenses when you write about time travel!!). The computers could make it all real, running the entire society through its course, at a greatly accelerated speed. The interactions could therefore be quite real, and all the interactions and all the minds and the rippling social effects could all be implemented. But the possibilities branch again, because although that could be true, and the future society could be genuinely changed, that could also be done by entirely replicating the cyberworld, and implementing the effects only in the parallel new cyber-universe. Doing either of these effectual options might prove very expensive, and obviously dangerous. Replicating things can be done, but you need a lot of computer power and storage to do it with everything affected, so it might be severely restricted. And policed.

But importantly, this sort of time travel could be done – you could go back in time to change the present. All the minds of all the people could be changed by someone going back in the past cyberspace records and doing something that would ripple forwards through time to change those same minds. It couldn’t be made fully clean, because some people for example might choose not to have kids in the revised edition, and although the cyberspace presence of their minds could be changed or deleted, you’d still have to dispose of their physical bodies and tidy up other physical residual effects. But not being clean is one of the things we’d expect for time travel. There would be residues, mess, paradoxes, and presumably this would all limit the things you’d be allowed to mess with. And we will need the time cops and time detectives and licenses and time cleaners and administrators and so on. But in our future cyberspace world, TIME TRAVEL WILL BE POSSIBLE. I can’t shout that loud enough. And please don’t ignore the italics, I am absolutely not suggesting it will be doable in the real world.

Fun! Trouble is, I’m going to be 90 in 2050 so I probably won’t have the energy any more.

Flat lenses – oozing potential

Lenses used to be curved. Not in the future thanks to Harvard scientists: https://www.seas.harvard.edu/news-events/press-releases/flat-lens-offers-perfect-image and http://pubs.acs.org/doi/abs/10.1021/nl302516v.

Ht http://nextbigfuture.com/ for making me aware.

Flat antennas aren’t new per se, phased array radio antennas have been around decades, but this is the first optical flat lens I am aware of. Theirs is pretty damned clever!

They are already looking at applications such as flat microscope objectives, and have probably covered most of the biggest opportunities. But just in case, and researchers do occasionally miss some opportunities, here are a few for free:

Kite telescopes

NASA are currently flying a 747-based telescope, chucking out huge quantities of water vapour into the high atmosphere, contributing to global warming to take over from their space shuttles. Ironic that such a warmist organisation should do that, but there we go. A large flat surface telescope could presumably be made into a high altitude kite, albeit one that needs a little engineering. And it wouldn’t add to stratospheric water vapour, or even add CO2.

High altitude telescopes could be used for ground imaging as well as space of course, and there would be many commercially viable businesses from this root, as well as military surveillance of course.

Smart glasses and contact lenses

I would like a pair of glasses that record everything I look at. Flat surface cameras would allow this. Glasses are much bigger than my pupil, so they could allow much higher resolution, so I’d be able to see at very high magnification without having to use binoculars. I’d also be able to see infrared, microwaves, see where the strongest cellphone signal is, enable a whole new kind of fashion using different spectra, add to augmented reality hugely by using the infrared channel to show real as well as digital auras. Wow, can’t wait for these! I am playing Assassin’s Creed again, and this is Eagle Sense and then some.

Of course, active contact lenses could also use this tech and offer intuitive optional zoom. I would see the world as normal, but by trying to focus on something in the distance, it would zoom in automatically. There have only been a few updates to my original active contact lens idea from 1991, http://www.futurizon.com/inventions/activecontactlensmay91.pdf but this will be another generation for its 21st anniversary.

Credit card cameras

The smartphone is causing the decline of standalone digital cameras. Digital jewellery will cause the decline of smartphones, but one of the things we still needed them for is the camera. Not any more. A simple credit card camera would work fine. Or maybe even a wristband could be used. Flat cameras will hasten the decline of smartphones.

Smart posters

If they can be printed cheaply, cameras could be built into much of the urban environment. Any poster could have video capture and storage built in, powered by solar, with some comms added too. What and who it sees could direct what it displays. Sure, you can do all that and then some with augmented reality, but augmented reality is a whole load of additional functionality that lives happily alongside other stuff, and doesn’t necessarily replace everything. Posters could be the next wave of Big Brother or the next wave of advertising. Or both.

Teletubby T-shirts revisited

When the Teletubbies were still new, I suggested that we’d be able to make clothes with video panels in using polymer screens. Teletubby t-shirts. Flat panel cameras would allow these to be two way. They could display images but also act as a cameras. They could link to cameras in other people’s t-shirts. You could have a camera on your back that links to the video image on your front, making you appear to have a big hole through you.

Thought recognition and smart microwaves

Wired carries another interesting article on brain wave recognition of PINs via the headsets used to play computer games. Old stuff in idea terms perhaps but it’s always nice to see practice catching up. http://www.wired.com/threatlevel/2012/08/brainwave-hacking/

It seems obvious that this could work nicely with the flat lens idea. A flat surface could image the electrical activity in the brain from a greater distance instead of having to use a helmet.

It would also be possible to put flat cameras on the inside surfaces of microwave ovens, looking at the food to see where the hot spots and cold spots are, so that the microwave beams could be directed better to the areas needing heated.

I think that’s enough for now.

Nuclear weapons + ?

I was privileged and honoured in 2005 to be elected one of the Fellows of the World Academy of Art and Science. It is a mark of recognition and distinction that I wear with pride. The WAAS was set up by Einstein, Oppenheimer, Bertrand Russel and a few other great people, as a forum to discuss the big issues that affect the whole of humanity, especially the potential misuse of scientific discoveries, and by extension, technological developments. Not surprisingly therefore, one of their main programs from the outset has been the pursuit of the abolition of nuclear weapons. It’s a subject I have never written about before so maybe now is a good time to start. Most importantly, I think it’s now time to add others to the list.

There are good arguments on both sides of this issue.

In favour of nukes, it can be argued from a pragmatic stance that the existence of nuclear capability has contributed to reduction in the ferocity of wars. If you know that the enemy could resort to nuclear weapon use if pushed too far, then it may create some pressure to restrict the devastation levied on the enemy.

But this only works if both sides value lives of their citizens sufficiently. If a leader thinks he may survive such a war, or doesn’t mind risking his life for the cause, then the deterrent ceases to work properly. An all out global nuclear war could kill billions of people and leave the survivors in a rather unpleasant world. As Einstein observed, he wasn’t sure what weapons World War 3 would be fought with, but world war 4 would be fought with sticks and stones. Mutually assured destruction may work to some degree as a deterrent, but it is based on second guessing a madman. It isn’t a moral argument, just a pragmatic one. Wear a big enough bomb, and people might give you a wide berth.

Against nukes, it can be argued from a moral basis that such weapons should never be used in any circumstances, their capability to cause devastation beyond the limits that should be tolerated by any civilisation. Furthermore, any resources spent on creating and maintaining them are therefore wasted and could have been put to better more constructive use.

This argument is appealing, but lacks pragmatism in a world where some people don’t abide by the rules.

Pragmatism and morality often align with the right and left of the political spectrum, but there is a solution that keeps both sides happy, albeit an imperfect one. If all nuclear weapons can be removed, and stay removed, so that no-one has any or can build any, then pragmatically, there could be even more wars, and they may be even more prolonged and nasty, but the damage will be kept short of mutual annihilation. Terrorists and mad rulers wouldn’t be able to destroy us all in a nuclear Armageddon. Morally, we may accept the increased casualties as the cost of keeping the moral high ground and protecting human civilisation. This total disarmament option is the goal of the WAAS. Pragmatic to some degree, and just about morally digestible.

Another argument that is occasionally aired is the ‘what if?’ WW2 scenario. What if nuclear weapons hadn’t been invented? More people would probably have died in a longer WW2. If they had been invented and used earlier by the other side, and the Germans had won, perhaps we would have had ended up with a unified Europe with the Germans in the driving seat. Would that be hugely different from the Europe we actually have 65 years later anyway. Are even major wars just fights over the the nature of our lives over a few decades? What if the Romans or the Normans or Vikings had been defeated? Would Britain be so different today? ‘What if?’ debates get you little except interesting debate.

The arguments for and against nuclear weapons haven’t really moved on much over the years, but now the scope is changing a bit. They are as big a threat as ever, maybe more-so with the increasing possibility of rogue regimes and terrorists getting their hands on them, but we are adding other technologies that are potentially just as destructive, in principle anyway, and they could be weaponised if required.

One path to destruction that entered a new phase in the last few years is our messing around with the tools of biology. Biotechnology and genetic modification, synthetic biology, and the linking of external technology into our nervous systems are individual different strands of this threat, but each of them is developing quickly. What links all these is the increasing understanding, harnessing and ongoing development of processes similar to those that nature uses to make life. We start with what nature provides, reverse engineer some of the tools, improve on them, adapt and develop them for particular tasks, and then use these to do stuff that improves on or interacts with natural systems.

Alongside nuclear weapons, we have already become used to the bio-weapons threat based on genetically modified viruses or bacteria, and also to weapons using nerve gases that inhibit neural functioning to kill us. But not far away is biotech designed to change the way our brains work, potentially to control or enslave us. It is starting benignly of course, helping people with disabilities or nerve or brain disorders. But some will pervert it.

Traditional war has been based on causing enough pain to the enemy until they surrender and do as you wish. Future warfare could be based on altering their thinking until it complies with what you want, making an enemy into a willing ally, servant or slave. We don’t want to lose the great potential for improving lives, but we shouldn’t be naive about the risks.

The broad convergence of neurotechnology and IT is a particularly dangerous area. Adding artificial intelligence into the mix opens the possibility of smart adapting organisms as well as the Terminator style threats. Organisms that can survive in multiple niches, or hybrid nature/cyberspace ones that use external AI to redesign their offspring to colonise others. Organisms that penetrate your brain and take control.

Another dangerous offspring from better understanding of biology is that we now have clubs where enthusiasts gather to make genetically modified organisms. At the moment, this is benign novelty stuff, such as transferring a bio-luminescence gene or a fluorescent marker to another organism, just another after-school science club for gifted school-kids and hobbyist adults. But it is I think a dangerous hobby to encourage. With better technology and skill developing all the time, some of those enthusiasts will move on to designing and creating synthetic genes, some won’t like being constrained by safety procedures, and some may have accidents and release modified organisms into the wild that were developed without observing the safety rules. Some will use them to learn genetic design, modification and fabrication techniques and then work in secret or teach terrorist groups. Not all the members can be guaranteed to be fine upstanding members of the community, and it should be assumed that some will be people of ill intent trying to learn how to do the most possible harm.

At least a dozen new types of WMD are possible based on this family of technologies, even before we add in nanotechnology. We should not leave it too late to take this threat seriously. Whereas nuclear weapons are hard to build and require large facilities that are hard to hide, much of this new stuff can be done in garden sheds or ordinary office buildings. They are embryonic and even theoretical today, but that won’t last. I am glad to say that in organisations such as the Lifeboat Foundation (lifeboat.com), in many universities and R&D labs, and doubtless in military ones, some thought has already gone into defence against them and how to police them, but not enough. It is time now to escalate these kinds of threats to the same attention we give to the nuclear one.

With a global nuclear war, much of the life on earth could be destroyed, and that will become possible with the release of well-designed organisms. But I doubt if I am alone in thinking that the possibility of being left alive with my mind controlled by others may well be a fate worse than death.

Blocking Pirate Bay makes little sense

http://www.telegraph.co.uk/technology/news/9236667/Pirate-Bay-must-be-blocked-High-Court-tells-ISPs.html Justice Arnold ruled that ISPs must block their customers from accessing Pirate Bay. Regardless of the morality or legality of Pirate Bay, forcing ISPs to block access to it will cause them inconvenience and costs, but won’t fix the core problem of copyright materials being exchanged without permission from the owners.

I have never looked at the Pirate Bay site, but I am aware of what it offers. It doesn’t host material, but allows its users to download from each other. By blocking access to the Bay, the judge blocks another one of billions of ways to exchange data. Many others exist and it is very easy to set up new ones, so trying to deal with them one by one seems rather pointless. Pirate Bay’s users will simply use alternatives. If they were to block all current file sharing sites, others would spring up to replace them, and if need be, with technological variations that set them outside of any new legislation. At best judges could play a poor catch-up game in an eternal war between global creativity and the law. Because that is what this is.

Pirate Bay can only be blocked because it is possible to identify it and put it in court. It is possible to write software that doesn’t need a central site, or indeed any legally identifiable substance. It could for example be open-source software written and maintained by evolving adaptive AI, hidden behind anonymity, distributed algorithms and encryption walls, roaming freely among web servers and PCs, never stopping anywhere. It could be untraceable. It could use combinations of mobile or fixed phone nets, the internet, direct gadget-gadget comms and even use codes on other platforms such as newspapers. Such a system would be dangerous to build from a number of perspectives, but may be forced by actions to close alternatives. If people feel angered by arrogance and greed, they may be pushed down this development road. The only way to fully stop such a system would be to stop communication.

The simple fact is that technology that we depend on for most aspects of our lives also makes it possible to swap files, and to do so secretly as needed. We could switch it off, but our economy and society would collapse. To pretend otherwise is folly. Companies that feel abused should recognise that the world has moved on and they need to adapt their businesses to survive in the world today, not ask everyone to move back to the world of yesterday so that they can cope. Because we can’t and shouldn’t even waste time trying to. My copyright material gets stolen frequently. So what? I just write more. That model works fine for me. It ain’t broke, and trying to fix it without understanding how stuff works won’t protect anyone and will only make it worse for all of us.
