The future of I

Me, myself, I, identity, ego, self, lots of words for more or less the same thing. The way we think of ourselves evolves just like everything else. Perhaps we are still cavemen with better clothes and toys. You may be a man, a dad, a manager, a lover, a friend, an artist and a golfer and those are all just descendants of caveman, dad, tribal leader, lover, friend, cave drawer and stone thrower. When you play Halo as Master Chief, that is not very different from acting or putting a tiger skin on for a religious ritual. There have always been many aspects of identity and people have always occupied many roles simultaneously. Technology changes but it still pushes the same buttons that we evolved hundred thousands of years ago.

Will we develop new buttons to push? Will we create any genuinely new facets of ‘I’? I wrote a fair bit about aspects of self when I addressed the related topic of gender, since self perception includes perceptions of how others perceive us and attempts to project chosen identity to survive passing through such filters:

Self is certainly complex. Using ‘I’ simplifies the problem. When you say ‘I’, you are communicating with someone, (possibly yourself). The ‘I’ refers to a tailored context-dependent blend made up of a subset of what you genuinely consider to be you and what you want to project, which may be largely fictional. So in a chat room where people often have never physically met, very often, one fictional entity is talking to another fictional entity, with each side only very loosely coupled to reality. I think that is different from caveman days.

Since chat rooms started, virtual identities have come a long way. As well as acting out manufactured characters such as the heroes in computer games, people fabricate their own characters for a broad range of kinds of ‘shared spaces’, design personalities and act them out. They may run that personality instance in parallel with many others, possibly dozens at once. Putting on an act is certainly not new, and friends easily detect acts in normal interactions when they have known a real person a long time, but online interactions can mean that the fictional version is presented it as the only manifestation of self that the group sees. With no other means to know that person by face to face contact, that group has to take them at face value and interact with them as such, though they know that may not represent reality.

These designed personalities may be designed to give away as little as possible of the real person wielding them, and may exist for a range of reasons, but in such a case the person inevitably presents a shallow image. Probing below the surface must inevitably lead to leakage of the real self. New personality content must be continually created and remembered if the fictional entity is to maintain a disconnect from the real person. Holding the in-depth memory necessary to recall full personality aspects and history for numerous personalities and executing them is beyond most people. That means that most characters in shared spaces take on at least some characteristics of their owners.

But back to the point. These fabrications should be considered as part of that person. They are an ‘I’ just as much as any other ‘I’. Only their context is different. Those parts may only be presented to subsets of the role population, but by running them, the person’s brain can’t avoid internalizing the experience of doing so. They may be partly separated but they are fully open to the consciousness of that person. I think that as augmented and virtual reality take off over the next few years, we will see their importance grow enormously. As virtual worlds start to feel more real, so their anchoring and effects in the person’s mind must get stronger.

More than a decade ago, AI software agents started inhabiting chat rooms too, and in some cases these ‘bots’ become a sufficient nuisance that they get banned. The front that they present is shallow but can give an illusion of reality. In some degree, they are an extension of the person or people that wrote their code. In fact, some are deliberately designed to represent a person when they are not present. The experiences that they have can’t be properly internalized by their creators, so they are a very limited extension to self. But how long will that be true? Eventually, with direct brain links and transhuman brain extensions into cyberspace, the combined experiences of I-bots may be fully available to consciousness just the same as first hand experiences.

Then it will get interesting. Some of those bots might be part of multiple people. People’s consciousnesses will start to overlap. People might collect them, or subscribe to them. Much as you might subscribe to my blog, maybe one day, part of one person’s mind, manifested as a bot or directly ‘published’, will become part of your mind. Some people will become absorbed into the experience and adopt so many that their own original personality becomes diluted to the point of disappearance. They will become just an interference pattern of numerous minds. Some will be so infectious that they will spread widely. For many, it will be impossible to die, and for many others, their minds will be spread globally. The hive minds of Dr Who, then later the Borg on Star Trek are conceptual prototypes but as with any sci-fi, they are limited by the imagination of the time they were conceived. By the time they become feasible, we will have moved on and the playground will be far richer than we can imagine yet.

So, ‘I’ has a future just as everything else. We may have just started to add extra facets a couple of decades ago, but the future will see our concept of self evolve far more quickly.


I got asked by a reader whether I worry about this stuff. Here is my reply:

It isn’t the technology that worries me so much that humanity doesn’t really have any fixed anchor to keep human nature in place. Genetics fixed our biological nature and our values and morality were largely anchored by the main religions. We in the West have thrown our religion in the bin and are already seeing a 30 year cycle in moral judgments which puts our value sets on something of a random walk, with no destination, the current direction governed solely by media and interpretation and political reaction to of the happenings of the day. Political correctness enforces subscription to that value set even more strictly than any bishop ever forced religious compliance. Anyone that thinks religion has gone away just because people don’t believe in God any more is blind.

Then as genetics technology truly kicks in, we will be able to modify some aspects of our nature. Who knows whether some future busybody will decree that a particular trait must be filtered out because it doesn’t fit his or her particular value set? Throwing AI into the mix as a new intelligence alongside will introduce another degree of freedom. So already several forces acting on us in pretty randomized directions that can combine to drag us quickly anywhere. Then the stuff above that allows us to share and swap personality? Sure I worry about it. We are like young kids being handed a big chemistry set for Christmas without the instructions, not knowing that adding the blue stuff to the yellow stuff and setting it alight will go bang.

I am certainly no technotopian. I see the enormous potential that the tech can bring and it could be wonderful and I can’t help but be excited by it. But to get that you need to make the right decisions, and when I look at the sorts of leaders we elect and the sorts of decisions that are made, I can’t find the confidence that we will make the right ones.

On the good side, engineers and scientists are usually smart and can see most of the issues and prevent most of the big errors by using comon industry standards, so there is a parallel self-regulatory system in place that politicians rarely have any interest in. On the other side, those smart guys unfortunately will usually follow the same value sets as the rest of the population. So we’re quite likely to avoid major accidents and blowing ourselves up or being taken over by AIs. But we’re unlikely to avoid the random walk values problem and that will be our downfall.

So it could be worse, but it could be a whole lot better too.


The future of euthanasia and suicide

Another extract from You Tomorrow, one that is very much in debate at the moment, it is an area that needs wise legislation, but I don’t have much confidence that we’ll get it. I’ll highlight some of the questions here, but since I don’t have many answers, I’ll illustrate why: they are hard questions.

Sadly, some people feel the need to end their own lives and an increasing number are asking for the legal right to assisted suicide. Euthanasia is increasingly in debate now too, with some health service practices bordering on it, some would say even crossing the boundary. Suicide and euthanasia are inextricably linked, mainly because it is impossible to know for certain what is in someone’s mind, and that is the basis of the well-known slippery slope from assisted suicide to euthanasia.

The stages of progress are reasonably clear. Is the suicide request a genuine personal decision, originating from that person’s free thoughts, based solely on their own interests? Or is it a personal decision influenced by the interests of others, real or imagined? Or is it a personal decision made after pressure from friends and relatives who want the person to die peacefully rather than suffer, with the best possible interests of the person in mind? In which case, who first raised the possibility of suicide as a potential way out? Or is it a personal decision made after pressure applied because relatives want rid of the person, perhaps over-eager to inherit or wanting to end their efforts to care for them? Guilt can be a powerful force and can be applied very subtly indeed over a period of time.

If the person is losing their ability to communicate a little, perhaps a friend or relative may help interpret their wishes to a doctor. From here, it is a matter of degree of communication skill loss and gradual increase of the part relatives play in guiding the doctor’s opinion of whether the person genuinely wants to die. Eventually, the person might not be directly consulted because their relatives can persuade a doctor that they really want to die but can’t say so effectively. Not much further along the path, people make their minds up what is in the best interests of another person as far as living or dying goes. It is a smooth path between these many small steps from genuine suicide to euthanasia. And that all ignores all the impact of possible alternatives such as pain relief, welfare, special care etc. Interestingly, the health services seem to be moving down the euthanasia route far faster than the above steps would suggest, skipping some of them and going straight to the ‘doctor knows best’ step.

Once the state starts to get involved in deciding cases, even by abdicating it to doctors, it is a long but easy road to Logan’s run, where death is compulsory at a certain age, or a certain care cost, or you’ve used up your lifetime carbon credit allocation.

There are sometimes very clear cases where someone obviously able to make up their own mind has made a thoroughly thought-through decision to end their life because of ongoing pain, poor quality of life and no hope of any cure or recovery, the only prospect being worsening condition leading to an undignified death. Some people would argue with their decision to die, others would consider that they should be permitted to do so in such clear circumstances, without any fear for their friends or relatives being prosecuted.

There are rarely razor-sharp lines between cases; situations can get blurred sometimes because of the complexity of individual lives, and because judges have their own personalities and differ slightly in their judgements. There is inevitably another case slightly further down the line that seems reasonable to a particular judge in the circumstances, and once that point is passed, and accepted by the courts, other cases with slightly less-defined circumstances can use it to help argue theirs. This is the path by which most laws evolve. They start in parliament and then after implementation, case law and a gradually changing public mind-set or even the additive effects of judges’ ideologies gradually evolve them into something quite different.

It seems likely given current trends and pressures that one day, we will accept suicide, and then we may facilitate it. Then, if we are not careful, it may evolve into euthanasia by a hundred small but apparently reasonable steps, and if we don’t stop it in time, one day we might even have a system like the one in the film ‘Logan’s Run’.

 Suicide and euthanasia are certainly gradually becoming less shocking to people, and we should expect that in the far future both will become more accepted. If you doubt that society can change its attitudes quickly, it actually only takes about 30 years to get a full reversal. Think of how long it took for homosexuality to change from condemned to fashionable, or how long abortion took from being something a woman would often be condemned for to something that is now a woman’s right to choose. Each of these took only 3 decades for a full 180 degree turnaround. Attitudes to the environment switched from mad panic about a coming ice age to mad panic about global warming in just 3 decades too, and are already switching back again towards ice age panic. If the turn in attitudes to suicide started 10 years ago, then we may have about 20 years left before it is widely accepted as a basic right that is only questioned by bigots. But social change aside, the technology will make the whole are much more interesting.

As I argued earlier, the very long term (2050 and beyond) will bring technology that allows people to link their brains to the machine world, perhaps using nanotech implants connected to each synapse to relay brain activity to a high speed neural replica hosted by a computer. This will have profound implications for suicide too. When this technology has matured, it will allow people to do wonderful things such as using machine sensors as extensions to their own capabilities. They will be able to use android bodies to move around and experience distant places and activities as if they were there in person. For people who feel compelled to end it all because of disability, pain or suffering, an alternative where they could effectively upload their mind into an android might be attractive. Their quality of life could improve dramatically at least in terms of capability. We might expect that pain and suffering could be dealt with much more effectively too if we have a direct link into the brain to control the way sensations are dealt with. So if that technology does progress as I expect, then we might see a big drop in the number of people who want to die.

But the technology options don’t stop there. If a person has a highly enhanced replica of their own brain/mind, in the machine world, people will begin to ask why they need the original. The machine world could give them greater sensory ability, greater physical ability, and greater mental ability. Smarter, with better memory, more and better senses, connected to all the world’s knowledge via the net, able effectively to wander around the world at the speed of light, and being connected directly to other people’s minds when you want, and doing so without fear of ageing, ill health of pain, this would seem a very attractive lifestyle. And it will become possible this century, at low enough cost for anyone to afford.

What of suicide then? It might not seem so important to keep the original body, especially if it is worn out or defective, so even without any pain and suffering, some people might decide to dispose of their body and carry on their lives without it. Partial suicide might become possible. Aside from any religious issues, this would be a hugely significant secular ethical issue. Updating the debate today, should people be permitted to opt out of physical existence, only keeping an electronic copy of their mind, timesharing android bodies when they need to enter the physical world? Should their families and friends be able to rebuild their loved ones electronically if they die accidentally? If so, should people be able to rebuild several versions, each representing the deceased’s different life stages, or just the final version, which may have been ill or in decline?

And then the ethical questions get even trickier. If it is possible to replicate the brain’s structure and so capture the mind, will people start to build ‘restore points’, where they make a permanent record of the state of their self at a given moment? If they get older and decide they could have run their lives better, they might be able to start again from any restore point. If the person exists in cyberspace and has disposed of their physical body, what about ownership of their estate? What about working and living in cyberspace? Will people get jobs? Will they live in virtual towns like the Sims? Indeed, in the same time frame, AI will have caught up and superseded humans in ability. Maybe Sims will get bored in their virtual worlds and want to end it all by migrating to the real world. Maybe they could swap bodies with someone coming the other way?

What will the State do when it is possible to reduce costs and environmental impact by migrating people into the virtual universe? Will it then become socially and politically acceptable, even compulsory when someone reaches a given age or costs too much for health care?

So perhaps suicide has an interesting future. It might eventually decline, and then later increase again, but in many very different forms, becoming a whole range of partial suicide options. But the scariest possibility is that people may not be able to die completely. If their body is an irrelevance, and there are many restore points from which they can be recovered, friends, family, or even the state might keep them ‘alive’ as long as they are useful. And depending on the law, they might even become a form of slave labour, their minds used for information processing or creativity whether they wish it or not. It has often truly been noted that there are worse fates than death.

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.

Future human evolution

I’ve done patches of work on this topic frequently over the last 20 years. It usually features in my books at some point too, but it’s always good to look afresh at anything. Sometimes you see something you didn’t see last time.

Some of the potential future is pretty obvious. I use the word potential, because there are usually choices to be made, regulations that may or may not get in the way, or many other reasons we could divert from the main road or even get blocked completely.

We’ve been learning genetics now for a long time, with a few key breakthroughs. It is certain that our understanding will increase, less certain how far people will be permitted to exploit the potential here in any given time frame. But let’s take a good example to learn a key message first. In IVF, we can filter out embryos that have the ‘wrong’ genes, and use their sibling embryos instead. Few people have a problem with that. At the same time, pregnant women may choose an abortion if they don’t want a child when they discover it is the wrong gender, but in the UK at least, that is illegal. The moral and ethical values of our society are on a random walk though, changing direction frequently. The social assignment of right and wrong can reverse completely in just 30 years. In this example, we saw a complete reversal of attitudes to abortion itself within 30 years, so who is to say we won’t see reversal on the attitude to abortion due to gender? It is unwise to expect that future generations will have the same value sets. In fact, it is highly unlikely that they will.

That lesson likely applies to many technology developments and quite a lot of social ones – such as euthanasia and assisted suicide, both already well into their attitude reversal. At some point, even if something is distasteful to current attitudes, it is pretty likely to be legalized eventually, and hard to ban once the door is opened. There will always be another special case that opens the door a little further. So we should assume that we may eventually use genetics to its full capability, even if it is temporarily blocked for a few decades along the way. The same goes for other biotech, nanotech, IT, AI and any other transhuman enhancements that might come down the road.

So, where can we go in the future? What sorts of splits can we expect in the future human evolution path? It certainly won’t remain as just plain old homo sapiens.

I drew this evolution path a long time ago in the mid 1990s:

human evolution 1

It was clear even then that we could connect external IT to the nervous system, eventually the brain, and this would lead to IT-enhanced senses, memory, processing, higher intelligence, hence homo cyberneticus. (No point in having had to suffer Latin at school if you aren’t allowed to get your own back on it later). Meanwhile, genetic enhancement and optimization of selected features would lead to homo optimus. Converging these two – why should you have to choose, why not have a perfect body and an enhanced mind? – you get homo hybridus. Meanwhile, in the robots and AI world, machine intelligence is increasing and we eventually we get the first self-aware AI/robot (it makes little sense to separate the two since networked AI can easily be connected to a machine such as a robot) and this has its own evolution path towards a rich diversity of different kinds of AI and robots, robotus multitudinus. Since both the AI world and the human world could be networked to the same network, it is then easy to see how they could converge, to give homo machinus. This future transhuman would have any of the abilities of humans and machines at its disposal. and eventually the ability to network minds into a shared consciousness. A lot of ordinary conventional humans would remain, but with safe upgrades available, I called them homo sapiens ludditus. As they watch their neighbors getting all the best jobs, winning at all the sports, buying everything, and getting the hottest dates too, many would be tempted to accept the upgrades and homo sapiens might gradually fizzle out.

My future evolution timeline stayed like that for several years. Then in the early 2000s I updated it to include later ideas:

human evolution 2

I realized that we could still add AI into computer games long after it becomes comparable with human intelligence, so games like EA’s The Sims might evolve to allow entire civilizations living within a computer game, each aware of their existence, each running just as real a life as you and I. It is perhaps unlikely that we would allow children any time soon to control fully sentient people within a computer game, acting as some sort of a god to them, but who knows, future people will argue that they’re not really real people so it’s OK. Anyway, you could employ them in the game to do real knowledge work, and make money, like slaves. But since you’re nice, you might do an incentive program for them that lets them buy their freedom if they do well, letting them migrate into an android. They could even carry on living in their Sims home and still wander round in our world too.

Emigration from computer games into our world could be high, but the reverse is also possible. If the mind is connected well enough, and enhanced so far by external IT that almost all of it runs on the IT instead of in the brain, then when your body dies, your mind would carry on living. It could live in any world, real or fantasy, or move freely between them. (As I explained in my last blog, it would also be able to travel in time, subject to certain very expensive infrastructural requirements.) As well as migrants coming via electronic immortality route, it would be likely that some people that are unhappy in the real world might prefer to end it all and migrate their minds into a virtual world where they might be happy. As an alternative to suicide, I can imagine that would be a popular route. If they feel better later, they could even come back, using an android.  So we’d have an interesting future with lots of variants of people, AI and computer game and fantasy characters migrating among various real and imaginary worlds.

But it doesn’t stop there. Meanwhile, back in the biotech labs, progress is continuing to harness bacteria to make components of electronic circuits (after which the bacteria are dissolved to leave the electronics). Bacteria can also have genes added to emit light or electrical signals. They could later be enhanced so that as well as being able to fabricate electronic components, they could power them too. We might add various other features too, but eventually, we’re likely to end up with bacteria that contain electronics and can connect to other bacteria nearby that contain other electronics to make sophisticated circuits. We could obviously harness self-assembly and self-organisation, which are also progressing nicely. The result is that we will get smart bacteria, collectively making sophisticated, intelligent, conscious entities of a wide variety, with lots of sensory capability distributed over a wide range. Bacteria Sapiens.

I often talk about smart yogurt using such an approach as a key future computing solution. If it were to stay in a yogurt pot, it would be easy to control. But it won’t. A collective bacterial intelligence such as this could gain a global presence, and could exist in land, sea and air, maybe even in space. Allowing lots of different biological properties could allow colonization of every niche. In fact, the first few generations of bacteria sapiens might be smart enough to design their own offspring. They could probably buy or gain access to equipment to fabricate them and release them to multiply. It might be impossible for humans to stop this once it gets to a certain point. Accidents happen, as do rogue regimes, terrorism and general mad-scientist type mischief.

And meanwhile, we’ll also be modifying nature. We’ll be genetically enhancing a wide range of organisms, bringing some back from extinction, creating new ones, adding new features, changing even some of the basic mechanism by which nature works in some cases. We might even create new kinds of DNA or develop substitutes with enhanced capability. We may change nature’s evolution hugely. With a mix of old and new and modified, nature evolves nicely into Gaia Sapiens.

We’re not finished with the evolution chart though. Here is the next one:

human evolution 3

Just one thing is added. Homo zombius. I realized eventually that the sci-fi ideas of zombies being created by viruses could be entirely feasible. A few viruses, bacteria and other parasites can affect the brains of the victims and change their behaviour to harness them for their own life cycle.

See for fun.

Bacteria sapiens could be highly versatile. It could make virus variants if need be. It could evolve itself to be able to live in our bodies, maybe penetrate our brains. Bacteria sapiens could make tiny components that connect to brain cells and intercept signals within our brains, or put signals back in. It could read our thoughts, and then control our thoughts. It could essentially convert people into remote controlled robots, or zombies as we usually call them. They could even control muscles directly to a point, so even if the zombie is decapitated, it could carry on for a short while. I used that as part of my storyline in Space Anchor. If future humans have widespread availability of cordless electricity, as they might, then it is far fetched but possible that headless zombies could wander around for ages, using the bacterial sensors to navigate. Homo zombius would be mankind enslaved by bacteria. Hopefully just a few people, but it could be everyone if we lose the battle. Think how difficult a war against bacteria would be, especially if they can penetrate anyone’s brain and intercept thoughts. The Terminator films looks a lot less scary when you compare the Terminator with the real potential of smart yogurt.

Bacteria sapiens might also need to be consulted when humans plan any transhuman upgrades. If they don’t consent, we might not be able to do other transhuman stuff. Transhumans might only be possible if transbacteria allow it.

Not done yet. I wrote a couple of weeks ago about fairies. I suggested fairies are entirely feasible future variants that would be ideally suited to space travel.

They’d also have lots of environmental advantages as well as most other things from the transhuman library. So I think they’re inevitable. So we should add fairies to the future timeline. We need a revised timeline and they certainly deserve their own branch. But I haven’t drawn it yet, hence this blog as an excuse. Before I do and finish this, what else needs to go on it?

Well, time travel in cyberspace is feasible and attractive beyond 2075. It’s not the proper real world time travel that isn’t permitted by physics, but it could feel just like that to those involved, and it could go further than you might think. It certainly will have some effects in the real world, because some of the active members of the society beyond 2075 might be involved in it. It certainly changes the future evolution timeline if people can essentially migrate from one era to another (there are some very strong caveats applicable here that I tried to explain in the blog, so please don’t misquote me as a nutter – I haven’t forgotten basic physics and logic, I’m just suggesting a feasible implementation of cyberspace that would allow time travel within it. It is really a cyberspace bubble that intersects with the real world at the real time front so doesn’t cause any physics problems, but at that intersection, its users can interact fully with the real world and their cultural experiences of time travel are therefore significant to others outside it.)

What else? OK, well there is a very significant community (many millions of people) that engages in all sorts of fantasy in shared on-line worlds, chat rooms and other forums. Fairies, elves, assorted spirits, assorted gods, dwarves, vampires, werewolves, assorted furry animals, assorted aliens, dolls,  living statues, mannequins, remote controlled people, assorted inanimate but living objects, plants and of course assorted robot/android variants are just some of those that already exist in principle; I’m sure I’ve forgotten some here and anyway, many more are invented every year so an exhaustive list would quickly become out of date. In most cases, many people already role play these with a great deal of conviction and imagination, not just in standalone games, but in communities, with rich cultures, back-stories and story-lines. So we know there is a strong demand, so we’re only waiting for their implementation once technology catches up, and it certainly will.

Biotech can do a lot, and nanotech and IT can add greatly to that. If you can design any kind of body with almost any kind of properties and constraints and abilities, and add any kind of IT and sensing and networking and sharing and external links for control and access and duplication, we will have an extremely rich diversity of future forms with an infinite variety of subcultures, cross-fertilization, migration and transformation. In fact, I can’t add just a few branches to my timeline. I need millions. So instead I will just lump all these extras into a huge collected category that allows almost anything, called Homo Whateverus.

So, here is the future of human (and associates) evolution, for the next 150 years. A few possible cross-links are omitted for clarity


I won’t be around to watch it all happen. But a lot of you will.


Will population grow again after 2050? To 15Bn?

We’ve been told for decades now that population will level off, probably around 2050, and population after that will likely decline. The world population will peak around 2050 at about 9.5 Billion. That’s pretty much the accepted wisdom at the moment.

The reasoning is pretty straight forward and seems sound, and the evidence follows it closely. People are becoming wealthier. Wealthier people have fewer kids. If you don’t expect your kids to die from disease or starvation before they’re grown up, you don’t need to make as many.

But what if it’s based on fallacy? What if it is just plain wrong? What if the foundations of that reasoning change dramatically by 2050 and it no longer holds true? Indeed. What if?

Before I continue, let me say that my book ‘Total Sustainability’, and my various optimistic writings and blogs about population growth all agree with the view that population will level off around 2050 and then slowly decline, while food supply and resource use will improve thanks to better technologies, thereby helping us to restore the environment. If population may increase again, I and many others will have to rethink.

The reason I am concerned now is that I just made another cross-link with the trend of rising wealth, which will allow even the most basic level of welfare to be set at a high level. It is like the citizen payment that the Swiss voted on recently. I suggested it a couple of years ago myself and in my books, and am in favour of it. Everyone would receive the same monthly payment from the state whether they work or not. The taxes due would then be calculated on the total income, regardless of how you get it, and I would use a flat tax for that too. Quite simple and fair. Only wealthier people pay any tax and then according to how wealthy they are. My calculations say that by 2050, everyone in the UK could get £30,000 a year each (in today’s money) based on the typical level of growth we’ve seen in recent decades (ignoring the recession years). In some countries it would be even higher, in some less, but the cost of living is also less in many countries. In many countries welfare could be as generous as average wages are today.

So by 2050, people in many countries could have an income that allows them to survive reasonably comfortably, even without having a job. That won’t stop everyone working, but it will make it much easier for people who want to raise a family to do so without economic concerns or having to go out to work. It will become possible to live comfortably without working and raise a family.

We know that people tend to have fewer kids as they become wealthier, but there are a number of possible reasons for that. One is the better survival chances for children. That may still have an effect in the developing world, but has little effect in richer countries, so it probably won’t have any impact on future population levels in those countries. Another is the need to work to sustain the higher standard of living one has become used to, to maintain a social status and position, and the parallel reluctance to have kids that will make that more difficult. While a small number of people have kids as a means to solicit state support, but that must be tiny compared to the numbers who have fewer so that they can self sustain. Another reason is that having kids impedes personal freedom, impacts on social life and sex life and adds perhaps unwelcome responsibility. These reasons are all vulnerable to the changes caused by increasing welfare and consequential attitudes. There are probably many other reasons too. 

Working and having fewer kids allows a higher standard of living than having kids and staying at home to look after them, but most people are prepared to compromise on material quality of life to some degree to get the obvious emotional rewards of having kids. Perhaps people are having fewer kids as they get wealthier because the drop of standard of living is too high, or the risks too high. If the guaranteed basic level of survival is comfortable, there is little risk. If a lot of people choose not to work and just live on that, there will also be less social stigma in not working, and more social opportunities from having more people in the same boat. So perhaps we may reasonably deduce that making it less uncomfortable to stop work and have more kids will create a virtuous circle of more and more people having more kids.

I won’t go as far as saying that will happen, just that it might. I don’t know enough about the relative forces that make someone decide whether to have another child. It is hard to predetermine the social attitudes that will prevail in 2050 and beyond, whether people will feel encouraged or deterred from having more kids.

My key point here is that the drop in fertility we see today due to increasing wealth might only hold true up to a certain point, beyond which it reverses. It may simply be that the welfare and social floor is too low to offer a sufficient safety net for those considering having kids, so they choose not to. If the floor is raised thanks to improving prosperity, as it might well be, then population could start to rise quickly again. The assumption that population will peak at 9 or 9.5 billion and then fall might be wrong. It could rise to up to 15 billion, at which point other factors will start to reassert themselves. If our assumptions on age of death are also underestimates, it could go even higher.

And another new book: You Tomorrow, 2nd Edition

I wrote You Tomorrow two years ago. It was my first ebook, and pulled together a lot of material I’d written on the general future of life, with some gaps then filled in. I was quite happy with it as a book, but I could see I’d allowed quite a few typos to get into the final work, and a few other errors too.

However, two years is a long time, and I’ve thought about a lot of new areas in that time. So I decided a few months ago to do a second edition. I deleted a bit, rearranged it, and then added quite a lot. I also wrote the partner book, Total Sustainability. It includes a lot of my ideas on future business and capitalism, politics and society that don’t really belong in You Tomorrow.

So, now it’s out on sale on Amazon in paper, at £9.00 and in ebook form at £3.81 (guessing the right price to get a round number after VAT is added is beyond me. Did you know that paper books don’t have VAT added but ebooks do?)

And here’s a pretty picture:


Future gender equality – legally recognise everyone’s male and female sides

My writing on the future of gender and same-sex reproduction now forms a section of my new book You Tomorrow, Second Edition, on the future of humanity, gender, lifestyle and our surroundings. Available from Amazon as paper and ebook.


Has the sisterhood forgotten older women?

We just went through International Women’s Day and I was one of many people asked to write an essay on the above topic for a compendium of essays for the International Longevity Centre, highlighting problems faced by older women and asking if they have been forgotten by feminism.

The pdf of the whole compendium is downloadable from

At the moment of writing, it is available via Internet Explorer but not Chrome. I haven’t tested other browsers.

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 :

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.


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:

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?
