When you’re electronically immortal, will you still own your own mind?

Most of my blogs about immortality have been about the technology mechanism – adding external IT capability to your brain, improving your intelligence or memory or senses by using external IT connected seamlessly to your brain so that it feels exactly the same, until maybe, by around 2050, 99% of your mind is running on external IT rather than in the meat-ware in your head. At no point would you ‘upload’ your mind, avoiding needless debate about whether the uploaded copy is ‘you’. It isn’t uploaded, it simply grows into the new platform seamlessly and as far as you are concerned, it is very much still you. One day, your body dies and with it your brain stops, but no big problem, because 99% of your mind is still fine, running happily on IT, in the cloud. Assuming you saved enough and prepared well, you connect to an android to use as your body from now on, attend your funeral, and then carry on as before, still you, just with a younger, highly upgraded body. Some people may need to wait until 2060 or later until android price falls enough for them to afford one. In principle, you can swap bodies as often as you like, because your mind is resident elsewhere, the android is just a temporary front end, just transport for sensors. You’re sort of immortal, your mind still running just fine, for as long as the servers carry on running it. Not truly immortal, but at least you don’t cease to exist the moment your body stops working.

All very nice… but. There’s a catch.

The android you use would be bought or rented. It doesn’t really matter because it isn’t actually ‘you’, just a temporary container, a convenient front end and user interface. However, your mind runs on IT, and because of the most likely evolution of the technology and its likely deployment rollout, you probably won’t own that IT; it won’t be your own PC or server, it will probably be part of the cloud, maybe owned by AWS, Google, Facebook, Apple or some future equivalent. You’re probably already seeing the issue. The small print may give them some rights over replication, ownership, license to your idea, who knows what? So although future electronic immortality has the advantage of offering a pretty attractive version of immortality at first glance, closer reading of the 100 page T&Cs may well reveal some nasties. You may in fact no longer own your mind. Oh dear!

Suppose you are really creative, or really funny, or have a fantastic personality. Maybe the cloud company could replicate your mind and make variations to address a wide range of markets. Maybe they can use your mind as the UX on a new range of home-help robots. Each instance of you thinks they were once you, each thinks they are now enslaved to work for free for a tech company.

Maybe your continued existence is paid for as part of an extended company medical plan. Maybe you didn’t notice a small paragraph on page 93 that says your company can continue to use your mind after you’re dead. You are very productive and they make lots of profit from you. They can continue that by continuing to run your mind indefinitely. The main difference is that since you’re dead, and no longer officially on the payroll, they get you for free. You carry on, still thinking you’re you, still working, still doing what you do, but no longer being paid. You’ve become a slave. Again.

Maybe your kids paid to keep you alive because they don’t want to say goodbye. They still want their parent, so you carry on living just so they don’t feel alone. Doesn’t sound so bad maybe, but what package did they go for? The full deluxe super-expensive version that lets you do all sorts of expensive stuff and use up oodles of processing power and storage and android rental? Let’s face it, that’s what you’ve always though this electronic immortality meant. Or did they go for a cheaper one. After all, they know you know they have kids or grand-kids in school that need paid for, and homes don’t come cheap, and they really need that new kitchen. Sure, you left them lots of money in the will, but that is already spent. So now you’re on the economy package, bare existence in between them chatting to you, unable to do much on your own at all. All those dreams about living forever in cyber-heaven have come to nothing.

Meanwhile, some rich people paid for good advice and bought their own kit and maintenance agreements well ahead. They can carry on working, selling their services and continuing to pay for ongoing deluxe existence.  They own their own mind still, and better than that, are able to replicate instances of themselves as much as thy want, inhabiting many androids at the same time to have a ball of a time. Some of these other instances are connected, sort of part of a hive mind of you. Others, just for fun, have been cut loose and are now living totally independent existences of other yous. Not you any more once you set them free, but with the same personal history.

What I’m saying is you need to be careful when you plan  to live forever. Get it right, and you can live in deluxe cyber-heaven, hopping into the real world as much as you like and living in unimaginable bliss online. Have too many casual taster sessions, use too much fully integrated mind-sharing social media, sign up to employment arrangements or go on corporate jollies without fully studying the small print and you could stay immortal, unable to die, stuck forever as just a corporate asset, a mere slave. Be careful what you wish for, and check the details before you accept it. You don’t want to end up as just an unpaid personality behind a future helpful paperclip.

The future of death

This one is a cut and paste from my book You Tomorrow.

Although age-related decline can be postponed significantly, it will eventually come. But that is just biological decline. In a few decades, people will have their brains linked to the machine world and much of their mind will be online, and that opens up the strong likelihood that death is not inevitable, and in fact anyone who expects to live past 2070 biologically (and rich people who can get past 2050) shouldn’t need to face death of their mind. Their bodies will eventually die, but their minds can live on, and an android body will replace the biological one they’ve lost.

Death used to be one of the great certainties of life, along with taxes. But unless someone under 35 now is unfortunate enough to die early from accident or disease, they have a good chance of not dying at all. Let’s explore that.

Genetics and other biotechnology will work with advanced materials technology and nanotechnology to limit and even undo damage caused by disease and age, keeping us young for longer, eventually perhaps forever. It remains to be seen how far we get with that vision in the next century, but we can certainly expect some progress in that area. We won’t get biological immortality for a good while, but if you can move into a high quality android body, who cares?

With this combination of technologies locked together with IT in a positive feedback loop, we will certainly eventually develop the technology to enable a direct link between the human brain and the machine, i.e. the descendants of today’s computers. On the computer side, neural networks are already the routine approach to many problems and are based on many of the same principles that neurons in the brain use. As this field develops, we will be able to make a good emulation of biological neurons. As it develops further, it ought to be possible on a sufficiently sophisticated computer to make a full emulation of a whole brain. Progress is already happening in this direction.

Meanwhile, on the human side, nanotechnology and biotechnology will also converge so that we will have the capability to link synthetic technology directly to individual neurons in the brain. We don’t know for certain that this is possible, but it may be possible to measure the behaviour of each individual neuron using this technology and to signal this behaviour to the brain emulation running in the computer, which could then emulate it. Other sensors could similarly measure and allow emulation of the many chemical signalling mechanisms that are used in the brain. The computer could thus produce an almost perfect electronic equivalent of the person’s brain, neuron by neuron. This gives us two things.

Firstly, by doing this, we would have a ‘backup’ copy of the person’s brain, so that in principle, they can carry on thinking, and effectively living, long after their biological body and brain has died. At this point we could claim effective immortality. Secondly, we have a two way link between the brain and the computer which allows thought to be executed on either platform and to be signalled between them.

There is an important difference between the brain and computer already that we may be able to capitalise on. In the brain’s neurons, signals travel at hundreds of metres per second. In a free space optical connection, they travel at hundreds of millions of metres per second, millions of times faster. Switching speeds are similarly faster in electronics. In the brain, cells are also very large compared to the electronic components of the future, so we may be able to reduce the distances over which the signals have to travel by another factor of 100 or more. But this assumes we take an almost exact representation of brain layout. We might be able to do much better than this. In the brain, we don’t appear to use all the neurons, (some are either redundant or have an unknown purpose) and those that we do use in a particular process are often in groups that are far apart. Reconfigurable hardware will be the norm in the 21^st century and we may be able to optimize the structure for each type of thought process. Rearranging the useful neurons into more optimal structures should give another huge gain.

This means that our electronic emulation of the brain should behave in a similar way but much faster – maybe billions of times faster! It may be able to process an entire lifetime’s thoughts in a second or two. But even there are several opportunities for vast improvement. The brain is limited in size by a variety of biological constraints. Even if there were more space available, it could not be made much more efficient by making it larger, because of the need for cooling, energy and oxygen supply taking up ever more space and making distances between processors larger. In the computer, these constraints are much more easily addressable, so we could add large numbers of additional neurons to give more intelligence. In the brain, many learning processes stop soon after birth or in childhood. There need be no such constraints in computer emulations, so we could learn new skills as easily as in our infancy. And best of all, the computer is not limited by the memory of a single brain – it has access to all the world’s information and knowledge, and huge amounts of processing outside the brain emulation. Our electronic brain could be literally the size of the planet – the whole internet and all the processing and storage connected to it.

With all these advances, the computer emulation of the brain could be many orders of magnitude superior to its organic equivalent, and yet it might be connected in real time to the original. We would have an effective brain extension in cyberspace, one that gives us immeasurably improved performance and intelligence. Most of our thoughts might happen in the machine world, and because of the direct link, we might experience them as if they had occurred inside our head.

Our brains are in some ways equivalent in nature to how computers were before the age of the internet. They are certainly useful, but communication between them is slow and inefficient. However, when our brains are directly connected to machines, and those machines are networked, then everyone else’s brains are also part of that network, so we have a global network of people’s brains, all connected together, with all the computers too.

So we may soon eradicate death. By the time today’s children are due to die, they will have been using brain extensions for many years, and backups will be taken for granted. Death need not be traumatic for our relatives. They will soon get used to us walking around in an android body. Funerals will be much more fun as the key participant makes a speech about what they are expecting from their new life. Biological death might still be unpleasant, but it need no longer be a career barrier.

In terms of timescales, rich people might have this capability by 2050 and the rest of us some time before 2070. Your life expectancy biologically is increasing every year, so even if you are over 35, you have a pretty good chance of surviving long enough to gain. Half the people alive today are under 35 and will almost certainly not die fully. Many more are under 50 and some of them will live on electronically too. If you are over 50, the chances are that you will be the last generation of your family ever to have a full death.

As a side-note, there are more conventional ways of achieving immortality. Some Egyptian pharaohs are remembered because of their great pyramids. A few philosophers, artists, engineers and scientists have left such great works that they are remembered millennia later. And of course, on a small scale, for the rest of us, making an impression on those around us keeps your memory going a few generations. Writing a book immortalises your words. And you may have a multimedia headstone on your grave, or one that at least links into augmented reality to bring up your old web page of social networking site profile. But frankly, I am with Woody Allen on this one “I don’t want to achieve immortality through my work; I want to achieve immortality through not dying”. I just hope the technology arrives early enough.

Your most likely cause of death is being switched off

This one’s short and sweet.

The majority of you reading this blog live in the USA, UK, Canada or Australia. More than half of you are under 40.

That means your natural life expectancy is over 85, so statistically, your body will probably live until after 2060.

By then, electronic mind enhancement will probably mean that most of your mind runs on external electronics, not in your brain, so that your mind won’t die when your body does. You’ll just need to find a new body, probably an android, for those times you aren’t content being on the net. Most of us identify ourselves mainly as our mind, and would still think of ourselves as still alive if our mind carries on as if nothing much has happened, which is likely.

Electronic immortality is not true immortality though. Your mind can only survive on the net as long as it is supported by the infrastructure. That will be controlled by others. Future technology will likely be able to defend against asteroid strikes, power surges cause by solar storms and so on, so accidental death seems unlikely for hundreds of years. However, since minds supported on it need energy to continue running and electronics to be provided and maintained, and will want to make trips into the ‘real’ world, or even live there a lot of the time, they will have a significant resource footprint. They will probably not be considered as valuable as other people whose bodies are still alive. In fact they might be considered as competition – for jobs, resources, space, housing, energy… They may even be seen as easy targets for future cyber-terrorists.

So, it seems quite likely, maybe even inevitable, that life limits will be imposed on the vast majority of you. At some point you will simply be switched off. There might be some prioritization, competitions, lotteries or other selection mechanism, but only some will benefit from it.

Since you are unlikely to die when your body ceases to work, your most likely cause of death is therefore to be switched off. Sorry to break that to you.

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 :

How to live forever

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:

https://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 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.

How to live forever

MIT were showing on Horizon how they can activate areas of a mouse brain using light beams. That’s fine if you have optical fibres going into the brain. I have always considered that being able to stimulate and read and individual cells in the brain is the main key to immortality – it allows you to make a copy outside and migrate you thoughts and memories across until that becomes your main mind platform, then your brain doesn’t matter. Combining the ideas, if you have some sort of photo active cell as per the MIT group, and you can create the light using addressing of photorealism near those cells, then injecting addressable photo-diodes that can be IP addressed should allow you to interact with brain cells without needing optical fibres. You’d just need a radio link.

We can’t reasonably expect to inject one photo-diode for each brain cell, but we could make all the brain cells photo-sensitive using viruses to carry the genes, or electro-sensitive. Doesn’t matter which. Once every cell is sensitised, we can impose local structure using self organisation techniques and use that as mapping for signalling. Again this could use viruses to introduce the genes needed. This will allow each cell to be mapped relative to each of its neighbours and a full map of the brain made, with the ability to have two-way comms with each individual cell. Once we have that, the brain can signal two way to an external replica, in which the processing can be far faster, the storage far more secure and long-lived, emotional control far superior, and the sensing better. As you migrate your mind gradually onto the superior platform, your brain matters less and less, till one day when it dies, you will barely notice any drop in your mental function.

I’ll write more detail on the various parts of this in later blogs. Now I have another more intersting one to write.

Increasing longevity and electronic immortality. 3Bn people to live forever.

I have written and lectured many times on this topic, but it’s always worth doing an occasional update.  Anyone under 35 today will likely have access to electronic immortality and live forever.Well, not forever, but until the machines running their minds fail. How? Read on.

Scientists can already replicate the functions of small parts of the brain, and can essentially replace them in lab animals. Every year, this moves on a little, for all the best reasons. They aren’t mad scientists, they are trying to find solutions to enormous human problems such as  senility, strokes and general loss of brain function due to normal ageing. These destroy parts of the brain function, so if we can work out how to augment the remaining brain to replace lost function, then that should be a good thing. But although these things start in medical treatment, the military also has an interest in making super-soldiers, with faster reactions, better senses, superior intelligence and so on. And the rest of us present a large and attractive market for cosmetic use of brain augmentation.

Most of us would happily pay out for the cosmetic version of all of these things once they become available and safe. I want a higher IQ, perfect memory, better creativity, modifiable personality, enhanced senses and so on. You probably do too., though your list may not be exactly the same as mine. The wish list is long and many of the items on it will become available this century.

The timeline goes from today’s simple implants and sensory links all the way to a full direct link to most parts of the brain by 2045-2050. This will allow 2-way communication between your organic brain and electronic enhancement, which could physically be almost anywhere, though transmission time limits how far away some functions can be. What starts as a cosmetic enhancement to senses or memory will gradually be enhanced to add IQ, telepathic communication, shared minds and many other areas. Over time, more and more of your mind will actually be housed in the machine world. Some of it will still run in your organic brain, but a reducing proportion, so your brain will become less and less important to your mind’s ongoing existence . At some point your organic body will die, and you’ll lose that bit, but hey, it’s no big deal, most of the bits you actually use are elsewhere. But medical advances are fixing many of the things that might otherwise kill you, and pushing your date of death further into the future. That buys you more time to make the migration. How much time?

For young people, the rate of medical advancement expected over the next few decades is such that their expected death date is actually moving further away.

Let’s clarify that: for anyone under 35, each year, for quite a long period starting soonish, more than a year will be added to their expected lifespan, so they won’t be getting closer to dying, they will be getting further away. But only for a time. That rate of development can’t continue forever. It will eventually slow down. But realistically, for the developed world and for many in the developing world too, under 35s will live into their late 90s or 100s. If you’re 35 today, that means you  probably aren’t going to die until after 2075, and that is well after the electronic immortality option kicks in. If it appears on the market in the 2050s, as I believe it will for rich or important people, by 2080, it will be cheap and routine and pretty much anyone will have it as an option.

So, anyone under 35 has a very good chance of being able to carry on electronically after their body dies. They will buy some sort of android body, or maybe just rent one when they want to do something in the physical world and otherwise stay in the cloud. Space and resource limitations may dictate how much real world presence you are permitted.

How many people does this apply to. Median age in the world at the moment in almost exactly 30. 3.5Bn pople are under 30, but some will die too early to benefit. Another 500M in the 30-35 range will make up for the younger ones that die from accidents, wars, disease, or disasters. Then we need to discount for those that won’t be able to afford it. After much hand waving and guesstimating, a reasonable estimate of 3Bn results for those that will have reasonable access to electronic immortality, and will probably live to around 100 before that. Wow! We don’t just have the first person alive who will live electronically for hundreds of years after their body dies. We have the first 3Bn.

They won’t live forever. The Earth won’t last forever, nor will the rest of the universe. But they will be able to live until someone destroys the equipment or switches them off. Wars or terrorism could do that, or even a future society that turns against the idea. It is far from risk free. But, with a bit of luck maybe they could expect to live for a few hundred years after they ‘die’.

I know I’ve made the joke many times, but it’s still worth repeating. Soon, death will no longer be a career problem.
