How nigh is the end?

“We’re doomed!” is a frequently recited observation. It is great fun predicting the end of the world and almost as much fun reading about it or watching documentaries telling us we’re doomed. So… just how doomed are we? Initial estimate: Maybe a bit doomed. Read on.

My 2012 blog https://timeguide.wordpress.com/2012/07/03/nuclear-weapons/ addressed some of the possibilities for extinction-level events possibly affecting us. I recently watched a Top 10 list of threats to our existence on TV and it was similar to most you’d read, with the same errors and omissions – nuclear war, global virus pandemic, terminator scenarios, solar storms, comet or asteroid strikes, alien invasions, zombie viruses, that sort of thing. I’d agree that nuclear war is still the biggest threat, so number 1, and a global pandemic of a highly infectious and lethal virus should still be number 2. I don’t even need to explain either of those, we all know why they are in 1st and 2nd place.

The TV list included a couple that shouldn’t be in there.

One inclusion was an mega-eruption of Yellowstone or another super-volcano. A full-sized Yellowstone mega-eruption would probably kill millions of people and destroy much of civilization across a large chunk of North America, but some of us don’t actually live in North America and quite a few might well survive pretty well, so although it would be quite annoying for Americans, it is hardly a TEOTWAWKI threat. It would have big effects elsewhere, just not extinction-level ones. For most of the world it would only cause short-term disruptions, such as economic turbulence, at worst it would start a few wars here and there as regions compete for control in the new world order.

Number 3 on their list was climate change, which is an annoyingly wrong, albeit a popularly held inclusion. The only climate change mechanism proposed for catastrophe is global warming, and the reason it’s called climate change now is because global warming stopped in 1998 and still hasn’t resumed 17 years and 9 months later, so that term has become too embarrassing for doom mongers to use. CO2 is a warming agent and emissions should be treated with reasonable caution, but the net warming contribution of all the various feedbacks adds up to far less than originally predicted and the climate models have almost all proven far too pessimistic. Any warming expected this century is very likely to be offset by reduction in solar activity and if and when it resumes towards the end of the century, we will long since have migrated to non-carbon energy sources, so there really isn’t a longer term problem to worry about. With warming by 2100 pretty insignificant, and less than half a metre sea level rise, I certainly don’t think climate change deserves to be on any list of threats of any consequence in the next century.

The top 10 list missed two out by including climate change and Yellowstone, and my first replacement candidate for consideration might be the grey goo scenario. The grey goo scenario is that self-replicating nanobots manage to convert everything including us into a grey goo.  Take away the silly images of tiny little metal robots cutting things up atom by atom and the laughable presentation of this vanishes. Replace those little bots with bacteria that include electronics, and are linked across their own cloud to their own hive AI that redesigns their DNA to allow them to survive in any niche they find by treating the things there as food. When existing bacteria find a niche they can’t exploit, the next generation adapts to it. That self-evolving smart bacteria scenario is rather more feasible, and still results in bacteria that can conquer any ecosystem they find. We would find ourselves unable to fight back and could be wiped out. This isn’t very likely, but it is feasible, could happen by accident or design on our way to transhumanism, and might deserve a place in the top ten threats.

However, grey goo is only one of the NBIC convergence risks we have already imagined (NBIC= Nano-Bio-Info-Cogno). NBIC is a rich seam for doom-seekers. In there you’ll find smart yogurt, smart bacteria, smart viruses, beacons, smart clouds, active skin, direct brain links, zombie viruses, even switching people off. Zombie viruses featured in the top ten TV show too, but they don’t really deserve their own category and more than many other NBIC derivatives. Anyway, that’s just a quick list of deliberate end of world solutions – there will be many more I forgot to include and many I haven’t even thought of yet. Then you have to multiply the list by 3. Any of these could also happen by accident, and any could also happen via unintended consequences of lack of understanding, which is rather different from an accident but just as serious. So basically, deliberate action, accidents and stupidity are three primary routes to the end of the world via technology. So instead of just the grey goo scenario, a far bigger collective threat is NBIC generally and I’d add NBIC collectively into my top ten list, quite high up, maybe 3rd after nuclear war and global virus. AI still deserves to be a separate category of its own, and I’d put it next at 4th.

Another class of technology suitable for abuse is space tech. I once wrote about a solar wind deflector using high atmosphere reflection, and calculated it could melt a city in a few minutes. Under malicious automated control, that is capable of wiping us all out, but it doesn’t justify inclusion in the top ten. One that might is the deliberate deflection of a large asteroid to impact on us. If it makes it in at all, it would be at tenth place. It just isn’t very likely someone would do that.

One I am very tempted to include is drones. Little tiny ones, not the Predators, and not even the ones everyone seems worried about at the moment that can carry 2kg of explosives or Anthrax into the midst of football crowds. Tiny drones are far harder to shoot down, but soon we will have a lot of them around. Size-wise, think of midges or fruit flies. They could be self-organizing into swarms, managed by rogue regimes, terrorist groups, or set to auto, terminator style. They could recharge quickly by solar during short breaks, and restock their payloads from secret supplies that distribute with the swarm. They could be distributed globally using the winds and oceans, so don’t need a plane or missile delivery system that is easily intercepted. Tiny drones can’t carry much, but with nerve gas or viruses, they don’t have to. Defending against such a threat is easy if there is just one, you can swat it. If there is a small cloud of them, you could use a flamethrower. If the sky is full of them and much of the trees and the ground infested, it would be extremely hard to wipe them out. So if they are well designed to cause an extinction level threat, as MAD 2.0 perhaps, then this would be way up in the top tem too, 5th.

Solar storms could wipe out our modern way of life by killing our IT. That itself would kill many people, via riots and fights for the last cans of beans and bottles of water. The most serious solar storms could be even worse. I’ll keep them in my list, at 6th place

Global civil war could become an extinction level event, given human nature. We don’t have to go nuclear to kill a lot of people, and once society degrades to a certain level, well we’ve all watched post-apocalypse movies or played the games. The few left would still fight with each other. I wrote about the Great Western War and how it might result, see

https://timeguide.wordpress.com/2013/12/19/machiavelli-and-the-coming-great-western-war/

and such a thing could easily spread globally. I’ll give this 7th place.

A large asteroid strike could happen too, or a comet. Ones capable of extinction level events shouldn’t hit for a while, because we think we know all the ones that could do that. So this goes well down the list at 8th.

Alien invasion is entirely possible and could happen at any time. We’ve been sending out radio signals for quite a while so someone out there might have decided to come see whether our place is nicer than theirs and take over. It hasn’t happened yet so it probably won’t, but then it doesn’t have to be very probably to be in the top ten. 9th will do.

High energy physics research has also been suggested as capable of wiping out our entire planet via exotic particle creation, but the smart people at CERN say it isn’t very likely. Actually, I wasn’t all that convinced or reassured and we’ve only just started messing with real physics so there is plenty of time left to increase the odds of problems. I have a spare place at number 10, so there it goes, with a totally guessed probability of physics research causing a problem every 4000 years.

My top ten list for things likely to cause human extinction, or pretty darn close:

  1. Nuclear war
  2. Highly infectious and lethal virus pandemic
  3. NBIC – deliberate, accidental or lack of foresight (includes smart bacteria, zombie viruses, mind control etc)
  4. Artificial Intelligence, including but not limited to the Terminator scenario
  5. Autonomous Micro-Drones
  6. Solar storm
  7. Global civil war
  8. Comet or asteroid strike
  9. Alien Invasion
  10. Physics research

Not finished yet though. My title was how nigh is the end, not just what might cause it. It’s hard to assign probabilities to each one but someone’s got to do it.  So, I’ll make an arbitrarily wet finger guess in a dark room wearing a blindfold with no explanation of my reasoning to reduce arguments, but hey, that’s almost certainly still more accurate than most climate models, and some people actually believe those. I’m feeling particularly cheerful today so I’ll give my most optimistic assessment.

So, with probabilities of occurrence per year:

  1. Nuclear war:  0.5%
  2. Highly infectious and lethal virus pandemic: 0.4%
  3. NBIC – deliberate, accidental or lack of foresight (includes smart bacteria, zombie viruses, mind control etc): 0.35%
  4. Artificial Intelligence, including but not limited to the Terminator scenario: 0.25%
  5. Autonomous Micro-Drones: 0.2%
  6. Solar storm: 0.1%
  7. Global civil war: 0.1%
  8. Comet or asteroid strike 0.05%
  9. Alien Invasion: 0.04%
  10. Physics research: 0.025%

I hope you agree those are all optimistic. There have been several near misses in my lifetime of number 1, so my 0.5% could have been 2% or 3% given the current state of the world. Also, 0.25% per year means you’d only expect such a thing to happen every 4 centuries so it is a very small chance indeed. However, let’s stick with them and add them up. The cumulative probability of the top ten is 2.015%. Lets add another arbitrary 0.185% for all the risks that didn’t make it into the top ten, rounding the total up to a nice neat 2.2% per year.

Some of the ones above aren’t possible quite yet, but others will vary in probability year to year, but I think that won’t change the guess overall much. If we take a 2.2% probability per year, we have an expectation value of 45.5 years for civilization life expectancy from now. Expectation date for human extinction:

2015.5 + 45.5 years= 2061,

Obviously the probability distribution extends from now to eternity, but don’t get too optimistic, because on these figures there currently is only a 15% chance of surviving past this century.

If you can think of good reasons why my figures are far too pessimistic, by all means make your own guesses, but make them honestly, with a fair and reasonable assessment of how the world looks socially, religiously, politically, the quality of our leaders, human nature etc, and then add them up. You might still be surprised how little time we have left.

I’ll revise my original outlook upwards from ‘a bit doomed’.

We’re reasonably doomed.

Technology 2040: Technotopia denied by human nature

This is a reblog of the Business Weekly piece I wrote for their 25th anniversary.

It’s essentially a very compact overview of the enormous scope for technology progress, followed by a reality check as we start filtering that potential through very imperfect human nature and systems.

25 years is a long time in technology, a little less than a third of a lifetime. For the first third, you’re stuck having to live with primitive technology. Then in the middle third it gets a lot better. Then for the last third, you’re mainly trying to keep up and understand it, still using the stuff you learned in the middle third.

The technology we are using today is pretty much along the lines of what we expected in 1990, 25 years ago. Only a few details are different. We don’t have 2Gb/s per second to the home yet and AI is certainly taking its time to reach human level intelligence, let alone consciousness, but apart from that, we’re still on course. Technology is extremely predictable. Perhaps the biggest surprise of all is just how few surprises there have been.

The next 25 years might be just as predictable. We already know some of the highlights for the coming years – virtual reality, augmented reality, 3D printing, advanced AI and conscious computers, graphene based materials, widespread Internet of Things, connections to the nervous system and the brain, more use of biometrics, active contact lenses and digital jewellery, use of the skin as an IT platform, smart materials, and that’s just IT – there will be similarly big developments in every other field too. All of these will develop much further than the primitive hints we see today, and will form much of the technology foundation for everyday life in 2040.

For me the most exciting trend will be the convergence of man and machine, as our nervous system becomes just another IT domain, our brains get enhanced by external IT and better biotech is enabled via nanotechnology, allowing IT to be incorporated into drugs and their delivery systems as well as diagnostic tools. This early stage transhumanism will occur in parallel with enhanced genetic manipulation, development of sophisticated exoskeletons and smart drugs, and highlights another major trend, which is that technology will increasingly feature in ethical debates. That will become a big issue. Sometimes the debates will be about morality, and religious battles will result. Sometimes different parts of the population or different countries will take opposing views and cultural or political battles will result. Trading one group’s interests and rights against another’s will not be easy. Tensions between left and right wing views may well become even higher than they already are today. One man’s security is another man’s oppression.

There will certainly be many fantastic benefits from improving technology. We’ll live longer, healthier lives and the steady economic growth from improving technology will make the vast majority of people financially comfortable (2.5% real growth sustained for 25 years would increase the economy by 85%). But it won’t be paradise. All those conflicts over whether we should or shouldn’t use technology in particular ways will guarantee frequent demonstrations. Misuses of tech by criminals, terrorists or ethically challenged companies will severely erode the effects of benefits. There will still be a mix of good and bad. We’ll have fixed some problems and created some new ones.

The technology change is exciting in many ways, but for me, the greatest significance is that towards the end of the next 25 years, we will reach the end of the industrial revolution and enter a new age. The industrial revolution lasted hundreds of years, during which engineers harnessed scientific breakthroughs and their own ingenuity to advance technology. Once we create AI smarter than humans, the dependence on human science and ingenuity ends. Humans begin to lose both understanding and control. Thereafter, we will only be passengers. At first, we’ll be paying passengers in a taxi, deciding the direction of travel or destination, but it won’t be long before the forces of singularity replace that taxi service with AIs deciding for themselves which routes to offer us and running many more for their own culture, on which we may not be invited. That won’t happen overnight, but it will happen quickly. By 2040, that trend may already be unstoppable.

Meanwhile, technology used by humans will demonstrate the diversity and consequences of human nature, for good and bad. We will have some choice of how to use technology, and a certain amount of individual freedom, but the big decisions will be made by sheer population numbers and statistics. Terrorists, nutters and pressure groups will harness asymmetry and vulnerabilities to cause mayhem. Tribal differences and conflicts between demographic, religious, political and other ideological groups will ensure that advancing technology will be used to increase the power of social conflict. Authorities will want to enforce and maintain control and security, so drones, biometrics, advanced sensor miniaturisation and networking will extend and magnify surveillance and greater restrictions will be imposed, while freedom and privacy will evaporate. State oppression is sadly as likely an outcome of advancing technology as any utopian dream. Increasing automation will force a redesign of capitalism. Transhumanism will begin. People will demand more control over their own and their children’s genetics, extra features for their brains and nervous systems. To prevent rebellion, authorities will have little choice but to permit leisure use of smart drugs, virtual escapism, a re-scoping of consciousness. Human nature itself will be put up for redesign.

We may not like this restricted, filtered, politically managed potential offered by future technology. It offers utopia, but only in a theoretical way. Human nature ensures that utopia will not be the actual result. That in turn means that we will need strong and wise leadership, stronger and wiser than we have seen of late to get the best without also getting the worst.

The next 25 years will be arguably the most important in human history. It will be the time when people will have to decide whether we want to live together in prosperity, nurturing and mutual respect, or to use technology to fight, oppress and exploit one another, with the inevitable restrictions and controls that would cause. Sadly, the fine engineering and scientist minds that have got us this far will gradually be taken out of that decision process.

The Mediterranean Crisis

700 people recently drowned trying to get from North Africa into Europe. Politicians don’t want to let people drown, nor do they want an immigration problem. How might this be solved?

Looking from a humanitarian viewpoint, rescue boats are sometimes finding the refugee boats too late. If they were closer to the launch points they would find them earlier and fewer would drown. The boats are often inadequate too. People trafickers make huge profits extorted from the refugees. A humanitarian solution, and one that would also reduce incentives for traffickers, would be to offer free passage on safe boats for genuine conflict refugees, essentially a ferry service. This would need military protection due to the regional conflict they are fleeing. If safe free passage is on offer, numbers might increase, but read on.

For those that are not genuine refugees but criminals fleeing justice or terrorists wanting to enter Europe, no such passage should be provided.

There is another large group of refugees though – economic migrants. A billion people in Africa would be financially better off in Europe. They would not all want to come, but many would. So would hundreds of millions from other parts of the world if a better life is on offer. Europe cannot provide for all in the world who want a better life. Offering free passage and European citizenship to anyone that wants it is not possible. Even if those people risk their lives in order to win such passage, it still isn’t. Offering limited immigration, whether using lotteries or some sort of points system is feasible and politicians could debate acceptable numbers.

It is hard to check which people fit in which group, identifying those that are genuinely fleeing conflict or persecution and those who simply want a better life. This could be solved by using a staging post for processing just as many countries already do. In this crisis, Lampedusa is the closest European (Italian) Island to the source of many of the boats. Suppose it were used for camps for genuine conflict refugees. In this solution, entry into Europe would not be permitted but refugees could evacuate to there and return to Africa when the conflict allows.

Lampedusa is not very large though, only 20 square km. So perhaps other islands would be needed too. Or perhaps not. It may well be that very many of the refugees would choose instead to go to another African country, or to stay where they are rather than go to Lampedusa. With no entry to Europe on offer, economic migrants would not have any incentive to go there, nor would criminals or terrorists. Those needing safety would be able to get it and those just wanting a better life would have to face the same immigration rules as everyone else.

With fast processing of asylum requests at Lampedusa (obviously networking could allows them to be processed remotely from anywhere in Europe, spreading the asylum load), such a solution might work. Europe would still take some asylum seekers and the staging post population might remain manageable even without extra islands. The people otherwise drowning at sea would not use traffickers and their unsafe boats. Safe travel to a temporary safe haven means there is no need.

The traffickers would have nobody to traffic. Economic migrants might fill a few boats before it becomes clear that being sent to Lampedusa or returned to the African mainland are the only outcomes on offer. So they would soon give up.

This solution would end most of the drownings while still averting an unmanageable refugee crisis that spirals well beyond control. Temporary safe haven would be on offer to those that need it, on condition that the refugees return home when conditions permit. That surely is the least we can do. No drowning crisis, no refugee crisis, no immigration crisis. Surely even politicians could agree to that?

 

How to decide green policies

Many people in officialdom seem to love putting ticks in boxes. Apparently once all the boxes are ticked, a task can be put in the ‘mission accomplished’ cupboard and forgotten about. So watching some of the recent political debate in the run-up to our UK election, it occurred to me that there must be groups of people discussing ideas for policies and then having meetings to decide whether they tick the right boxes to be included in a manifesto. I had some amusing time thinking about how a meeting might go for the Green Party. A little preamble first.

I could write about any of the UK parties I guess. Depending on your choice of media nicknames, we have the Nasty Party, the Fruitcake Racist Party, the Pedophile Empathy Party, the Pedophile and Women Molesting Party, the National Suicide Party (though they get their acronym in the wrong order) and a few Invisible Parties. OK, I invented some of those based on recent news stories of assorted facts and allegations and make no assertion of any truth in any of them whatsoever. The Greens are trickier to nickname – ‘The Poverty and Oppression Maximization, Environmental Destruction, Economic Collapse, Anti-science, Anti-fun and General Misery Party’ is a bit of a mouthful. I like having greens around, just so long as they never win control. No matter how stupid a mistake I might ever make, I’ll always know that greens would have made a worse one.

So what would a green policy development meeting might be like? I’ll make the obvious assumption that the policies don’t all come from the Green MP. Like any party, there are local groups of people, presumably mostly green types in the wider sense of the word, who produce ideas to feed up the ladder. Many won’t even belong to any official party, but still think of themselves as green. Some will have an interest mainly in socialism, some more interested in environmentalism, most will be a blend of the two. And to be fair, most of them will be perfectly nice people who want to make the world a better place, just like the rest of us. I’ve met a lot of greens, and we do agree at least on motive even if I think they are wrong on most of their ideas of how to achieve the goals. We all want world peace and justice, a healthy environment and to solve poverty and oppression. The main difference between us is deciding how best to achieve all that.

So I’ll look at green debate generally as a source of the likely discussions, rather than any actual Green Party manifesto, even though that still looks pretty scary. To avoid litigation threats and keep my bank balance intact, I’ll state that this is only a personal imagining of what might go into such green meetings, and you can decide for yourself how much it matches up to the reality. It is possible that the actual Green Party may not actually run this way, and might not support some of the policies I discuss, which are included in this piece based on wider green debate, not the Green Party itself. Legal disclaimers in place, I’ll get on with my imagining:

Perhaps there might be some general discussion over the welcome coffee about how awful it is that some nasty capitalist types make money and there might be economic growth, how terrible it is that scientists keep discovering things and technologists keep developing them, how awful it is that people are allowed to disbelieve in a global warming catastrophe and still be allowed to roam free and how there should be a beautiful world one day where a green elite is in charge, the population has been culled down to a billion or two and everyone left has to do everything they say on pain of imprisonment or death. After coffee, the group migrates to a few nice recycled paper flip-charts to start filling them with brainstormed suggestions. Then they have to tick boxes for each suggestion to filter out the ones not dumb enough to qualify. Then make a nice summary page with the ones that get all the boxes ticked. So what boxes do they need? And I guess I ought to give a few real examples as evidence.

Environmental destruction has to be the first one. Greens must really hate the environment, since the majority of green policies damage it, but they manage to get them implemented via cunning marketing to useful idiots to persuade them that the environment will benefit. The idiots implement them thinking the environment will benefit, but it suffers.  Some quick examples:

Wind turbines are a big favorite of greens, but planted on peat bogs in Scotland, the necessary roads cause the bogs to dry out, emitting vast quantities of CO2 and destroying the peat ecosystem. Scottish wind turbines also kill eagles and other birds.

In the Far East, many bogs have been drained to grow palm oil for biofuels, another green favorite that they’ve managed to squeeze into EU law. Again, vast quantities of CO2, and again ecosystem destruction.

Forests around the world have been cut down to make room for palm oil plantations too, displacing local people, destroying an ecosystem to replace it with one to meet green fuel targets.

Still more forests have been cut down to enable new ones to be planted to cash in on  carbon offset schemes to keep corporate greens happy that they can keep flying to all those green conferences without feeling guilt. More people displaced, more destruction.

Staying with biofuels, a lot of organic waste from agriculture is converted to biofuels instead of ploughing it back into the land. Soil structure therefore deteriorates, damaging ecosystem and damaging future land quality. CO2 savings by making the bio-fuel are offset against locking the carbon up in soil organic matter so there isn’t much benefit even there, but the damage holds.

Solar farms are proliferating in the UK, often occupying prime agricultural land that really ought to be growing food for the many people in the world still suffering from malnutrition. The same solar panels could have been sent to otherwise useless desert areas in a sunny country and used to displace far more fossil fuels and save far more CO2 without reducing food production. Instead, people in many African countries have to use wood stoves favored by greens as sustainable, but which produce airborne particles that greatly reduce health. Black carbon resulting from open wood fires also contributes directly to warming.

Many of the above policy effects don’t just tick the environmental destruction box, but also the next ones poverty and oppression maximization. Increasing poverty resulted directly from increasing food prices as food was grown to be converted into bio-fuel. Bio-fuels as first implemented were a mind-numbingly stupid green policy. Very many of the world’s poorest people have been forcefully pushed out of their lands and into even deeper poverty to make space to grow bio-fuel crops. Many have starved or suffered malnutrition. Entire ecosystems have been destroyed, forests replaced, many animals pushed towards extinction by loss of habitat. More recently, even greens have realized the stupidity and these polices are slowly being fixed.

Other green policies see economic development by poor people as a bad thing because it increases their environmental footprint. The poor are therefore kept poor. Again, their poverty means they can’t use modern efficient technology to cook or keep warm, they have to chop trees to get wood to burn, removing trees damages soil integrity, helps flooding, burning them produces harmful particles and black carbon to increase warming. Furthermore, with too little money to buy proper food, some are forced to hunt or buy bushmeat, endangering animal species and helping to spread viruses between closely genetically-related animals and humans.

So a few more boxes appear. All the above polices achieved pretty much the opposite of what they presumably intended, assuming the people involved didn’t actually want to destroy the world. Maybe a counterproductive box needs to be ticked too.

Counterproductive links well to another of the green’s apparent goals, of economic collapse. They want to stop economic growth. They want to reduce obsolescence.  Obsolescence is the force that drives faster and faster progress towards devices that give us a high quality of life with a far lower environmental impact, with less resource use, lower energy use, and less pollution. If you slow obsolescence down because green dogma says it is a bad thing, all those factors worsen. The economy also suffers. The economy suffers again if energy prices are deliberately made very high by adding assorted green levies such as carbon taxes, or renewable energy subsidies.  Renewable energy subsidies encourage more oppression of people who really don’t want wind turbines nearby, causing them stress and health problems, disrupting breeding cycles of small wild animals in the areas, reducing the value of people’s homes, while making the companies that employ hem less able to compete internationally, so increasing bankruptcy, redundancy and making even more poverty. Meanwhile the rich wind farm owners are given lots of money from poor people who are forced to buy their energy and pay higher taxes for the other half of their subsidy. The poor take all the costs, the rich take all the benefits. That could be another box to tick, since it seems pretty universal in green policy So much for  policies that are meant to be socialist! Green manifesto policies would make some of these problems far worse still. Business would be strongly loaded with extra costs and admin, and the profits they can still manage to make would be confiscated to pay for the ridiculous spending plans. With a few Greens in power, damage will be limited and survivable. If they were to win control, our economy would collapse totally in a rapidly accelerating debt spiral.

Greens hate science and technology, another possible box to tick. I once chatted to one of the Green leaders (I do go to environmental events sometimes if I think I can help steer things in a more logical direction), and was told ‘the last thing we need is more science’. But it is science and technology that makes us able to live in extreme comfort today alongside a healthy environment. 100 years ago, pollution was terrible. Rivers caught fire. People died from breathing in a wide variety of pollutants. Today, we have clean water and clean air. Thanks to increasing CO2 levels – and although CO2 certainly does contribute to warming, though not as much as feared by warmist doom-mongers, it also has many positive effects – there is more global greenery today than decades ago. Plants thrive as CO2 levels increase so they are growing faster and healthier. We can grow more food and forests can recover faster from earlier green destruction.

The greens also apparently have a box that ‘prevents anyone having any fun’. Given their way, we’d be allowed no meat, our homes would all have to be dimly lit and freezing cold, we’d have to walk everywhere or wait for buses in the rain. Those buses would still burn diesel fuel, which kills thousands of people every year via inhalation of tiny particulates. When you get anywhere, you’d have to use ancient technologies that have to be fixed instead of replaced. You’d have to do stuff that doesn’t use much energy or involve eating anything nice, going anywhere nice because that would involve travel and travel is bad, except for greens, who can go to as many international conferences as they want.

So if the greens get their way, if people are dumb enough to fall for promises of infinite milk and honey for all, all paid for by taxing 3 bankers, then the world we’d live in would very quickly have a devastated environment, a devastated economy, a massive transfer of wealth from the poor to a few rich people, enormous oppression, increasing poverty, decreasing health, no fun at all. In short, with all the above boxes checked, the final summary box to get the policy into manifesto must be ‘increases general misery‘.

An interesting list of boxes to tick really. It seems that all truly green policies must:

  1. Cause environmental destruction
  2. Increase poverty and oppression
  3. Be counterproductive
  4. Push towards economic collapse
  5. Make the poor suffer all the costs while the rich (and Green elite) reap the benefits
  6. Impede further science and technology development
  7. Prevent anyone having fun
  8. Lead to general misery

This can’t be actually how they run their meetings I suppose: unless they get someone from outside with a working brain to tick the boxes, the participants would need to have some basic understanding of the actual likely consequences of their proposals and to be malign, and there is little evidence to suggest any of them do understand, and they are mostly not malign. Greens are mostly actually quite nice people, even the ones in politics, and I do really think they believe in what they are doing. Their hearts are usually in the right place, it’s just that their brains are missing or malfunctioning. All of the boxes get ticked, it’s just unintentionally.

I rest my case.

 

 

 

A glimmer of hope in a dark world

Looking at the news, it can be easy to see only a world full of death, destruction, poverty, environmental decay, rising terrorism and crime; a world full of greed and corruption, with fanaticism, prejudice and ignorance in place of reason and knowledge; a world with barriers replacing bridges. It is especially hard to see the leaders we so badly need to get us out of the mess. We have a collection of some of the worst western leaders of my lifetime, whose main skill seems to be marketing, avoiding answering legitimate questions put to them by their electorates, and always answering different questions that present their policies in a more favorable light. A reasonable person who just watches news and current affairs programs could get rather pessimistic about our future, heading towards hell in a cart driven by an idiot.

But a reasonable person should not just watch the news and current affairs. They should also watch and read other things. When they do so, they will see cause for hope. I study the future all day, almost every day. I am not pessimistic, nor am I an idealist. I am only interested in what will actually be, not in wearing politically tinted spectacles. I can see lots of things down the road, good and bad, but I see a future that is better than today. Not a utopia, but certainly not a dystopia, and better overall. If asked, I can spin a tale of doom as good as anyone, but only by leaving out half of the facts. I often address future problems in my blogs, but I still sleep well at night, confident that my descendants will have a happy and prosperous future.

Leaders come and go. Obama will not be recorded in history as one of America’s better presidents and he has done little for the credibility of the Nobel Peace Prize. Cameron will be remembered as one of our worst PMs, up there with Brown and (perish the thought) Miliband. Our drunkard EU president Juncker won’t shine either, more likely to increase corruption and waste than to deal with it. But we’ll get better leaders. Recessions also come and go. We may see another financial collapse any time now and maybe another after that, but the long term still looks good. Even during recession, progress continues. Better materials, better science, better medical tools and better drugs, better transport, better communications and computing, better devices, batteries and energy supplies. These all continue to improve, recession or not. So when recession finally subsides, we can buy a better lifestyle with less money. All that background development then feeds into recovered industry to accelerate it well past the point where recession arrived.

It makes sense therefore to treat recessions as temporary blockages on economic development. They are unpleasant but they don’t last. When economies become healthy again, development resumes at an accelerated rate thanks to latent development potential that has accumulated during them.

If we take 2.5% growth as fairly typical during healthy times, that adds up to prosperity very quickly. 2.5% doesn’t sound much, and you barely notice a 2.5% pay rise. But over 45 years it triples the size of an economy. Check it yourself 1.025 ^ 45 = 3.038. National debts might sound big compared to today’s economies but compared to 45 or 50 years time they are much less worrying. That assumes of course that we don’t keep electing parties that want to waste money by throwing it at national treasures rather than forcing them to become more efficient.

So there is economic hope for sure. Our kids will be far wealthier than us. In the UK, they are worried about debts they accumulate at university, but by mid-career, those will be ancient history and they’ll be far better off after that.

It isn’t all about personal wealth or even national wealth. Having more resources at your disposal makes it possible to do other things. Many countries today are worried about mass migrations. Migrations happen because of wars and because of enormous wealth differences. Most of us prefer familiarity, so would only move if we have to to get a better life for ourselves or our kids. If the global economy is three times bigger in 45 years, and 9 times bigger in 90 years, is genuine poverty really something we can’t fix? Of course it isn’t. With better science and technology, a reasonable comfortable lifestyle will be possible for everyone on the planet this century. We talk of citizen wages in developed countries. Switzerland could afford one any time now. The UK could afford a citizen wage equivalent to today’s average wage within 45 years (that means two average wages coming in for a childless couple living together and even more for families), the USA a little earlier. By 2100, everyone in the world could have a citizen wage equivalent in local spending parity terms to UK average wage today. People might still migrate, but it would be for reasons other than economic need.

If people are comfortable financially, wars will reduce too. Tribal and religious conflicts will still occur, but the fights over resources will be much reduced. Commercially motivated crime also reduces when comfort is available for free.

Extremist environmental groups see economic growth as the enemy of the environment. That is because they generally hate science and technology and don’t understand how they develop. In fact, technology generally gets cleaner and less resource hungry as it develops. A 150g (6oz) mobile not only replaces a ton of early 1990s gadgets but even adds lifestyle functionality. It uses less energy and less resource and improves life. Cars are far cleaner and far more efficient and use far less resources than their predecessors. Bridges and buildings too. Future technology will do that all over again. We will grow more and better food on less land, and free up land to return to nature. We’ll help nature recover, restore and nurture ecosystems. We’ll reduce pollution. The 2100 environment will be cleaner and healthier than today’s by far, and yet most people will lead vastly improved lives, with better food, better homes, better gadgets, better transport, better health, more social and business capability, more money to play with. There will still be some bad leaders, terrorist groups, rogue states, bad corporations, criminals, social problems.

It won’t be perfect by any means. Some people will sometimes have bad times, but on balance, it will be better. Utopia is theoretically possible, but people won’t let it happen, but it will be better for most people most of the time. We shouldn’t underestimate people’s capacity to totally screw things up, but those will be short term problems. We might even have wars, but they pass.

The world often looks like a dark place right now and lots of big problems lie ahead. But ignore the doomsayers, look beyond those, and the future actually looks pretty damned good!

 

Citizen wage and why under 35s don’t need pensions

I recently blogged about the citizen wage and how under 35s in developed countries won’t need pensions. I cut and pasted it below this new pic for convenience. The pic contains the argument so you don’t need to read the text.

Economic growth makes citizen wage feasible and pensions irrelevant

Economic growth makes citizen wage feasible and pensions irrelevant

If you do want to read it as text, here is the blog cut and pasted:

I introduced my calculations for a UK citizen wage in https://timeguide.wordpress.com/2013/04/08/culture-tax-and-sustainable-capitalism/, and I wrote about the broader topic of changing capitalism a fair bit in my book Total Sustainability. A recent article http://t.co/lhXWFRPqhn reminded me of my thoughts on the topic and having just spoken at an International Longevity Centre event, ageing and pensions were in my mind so I joined a few dots. We won’t need pensions much longer. They would be redundant if we have a citizen wage/universal wage.

I argued that it isn’t economically feasible yet, and that only a £10k income could work today in the UK, and that isn’t enough to live on comfortably, but I also worked out that with expected economic growth, a citizen wage equal to the UK average income today (£30k) would be feasible in 45 years. That level will sooner be feasible in richer countries such as Switzerland, which has already had a referendum on it, though they decided they aren’t ready for such a change yet. Maybe in a few years they’ll vote again and accept it.

The citizen wage I’m talking about has various names around the world, such as universal income. The idea is that everyone gets it. With no restrictions, there is little running cost, unlike today’s welfare which wastes a third on admin.

Imagine if everyone got £30k each, in today’s money. You, your parents, kids, grandparents, grand-kids… Now ask why you would need to have a pension in such a system. The answer is pretty simple. You won’t.  A retired couple with £60k coming in can live pretty comfortably, with no mortgage left, and no young kids to clothe and feed. Let’s look at dates and simple arithmetic:

45 years from now is 2060, and that is when a £30k per year citizen wage will be feasible in the UK, given expected economic growth averaging around 2.5% per year. There are lots of reasons why we need it and why it is very likely to happen around then, give or take a few years – automation, AI, decline of pure capitalism, need to reduce migration pressures, to name just a few

Those due to retire in 2060 at age 70 would have been born in 1990. If you were born before that, you would either need a small pension to make up to £30k per year or just accept a lower standard of living for a few years. Anyone born in 1990 or later would be able to stop working, with no pension, and receive the citizen wage. So could anyone else stop and also receive it. That won’t cause economic collapse, since most people will welcome work that gives them a higher standard of living, but you could just not work, and just live on what today we think of as the average wage, and by then, you’ll be able to get more with it due to reducing costs via automation.

So, everyone after 2060 can choose to work or not to work, but either way they could live at least comfortably. Anyone less than 25 today does not need to worry about pensions. Anyone less than 35 really doesn’t have to worry much about them, because at worst they’ll only face a small shortfall from that comfort level and only for a few years. I’m 54, I won’t benefit from this until I am 90 or more, but my daughter will.

Summarising:

Are you under 25 and living in any developed country? Then don’t pay into a pension, you won’t need one.

Under 35, consider saving a little over your career, but only enough to last you a few years.

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 21st 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.

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 http://io9.com/12-real-parasites-that-control-the-lives-of-their-hosts-461313366 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.

https://timeguide.wordpress.com/2014/06/06/fairies-will-dominate-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

evolution

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

 

Time Travel: Cyberspace opens a rift in the virtual time-space continuum

Dr Who should have written this but he didn’t so I have to. We keep seeing those cute little tears in space-time in episodes of the BBC’s Dr Who, that let through Daleks and Cybermen and other nasties. (As an aside, how come feminists never seem to object to the term Cybermen, even though 50% of them are made from women?). Dr Who calls them rifts, and it allegedly needs the energy of entire star systems to open and close them. So, not much use as a weapon then, but still a security issue if our universe leaks.

Sci-fi authors have recognized the obvious dangers of time-space rifts for several decades. They cause problems with causality as well. I got a Physics degree a long time ago (well, Applied Mathematics and Theoretical Physics, but all the maths was EM theory, quantum mechanics and relativity, so it was really a physics degree), but I have never really understood fully why causality is such a big deal. Sure it needs a lot of explaining if it fails, but why would an occasional causal error cause such a huge problem? The Daleks are far more worrying. **Politically incorrect joke censored**

I just wrote about time travel again. All competent physicists rightly switch on their idiot filters automatically on hearing any of the terms ‘cold fusion’, ‘telekinetic’, ‘psychic’, ‘perpetual motion machine’, ‘time travel’ or ‘global warming catastrophe’. Sorry, that last one just sort of crept in there. Time travel is not really possible, unless you’re inside a black hole or you’re talking about a particle shifting atoseconds in a huge accelerator or GPS relativistic corrections or something. A Tardis isn’t going to be here any time soon and may be impossible and never ever come. However, there is a quite real cyberspace route to quite real time travel that will become feasible around 2075, a virtual rift if you like, but no need to activate idiot filters just yet, it’s only a virtual rift, a rift in a sandbox effectively, and it won’t cause the universe to collapse or violate any known laws of physics. So, hit the temporary override button on your idiot filter. It’s a fun thought experiment that gets more and more fun the more you look at it. (Einstein invented thought experiments to investigate relativity, because he couldn’t do any real experiments with the technology of his time. We can’t verify this sort of time travel experimentally yet so thought experiment is the only mechanism available. Sadly, I don’t have Einstein’s brain to hand, but some aspects at least are open to the rest of us to explore.) The hypothesis here is that if you can make a platform that stores the state of all the minds in a system continuously over a period from A to B, and that runs all those minds continuously using a single editable record, then you can travel in time freely between A and B.  Now we need to think it through a bit to test the hypothesis and see what virtual physics we can learn from it, see how real it would be and what it would need and lead to.

I recognized on my first look at it in

that cyberspace offers a time travel cheat. The basic idea, to save you reading it now that it’s out of date, is that some time soon after 2050 – let’s take 2075 as the date that crowd-funding enables its implementation – we’ll all be able to connect our brains so well to the machine world that it will be possible to share thoughts and consciousness, sensations, effectively share bodies, live electronically until all the machines stop working, store your mind as a snapshot periodically in case you want to restore to an earlier backup and do all sorts of really fun things like swapping personalities. (You can see why it might attract the required funding so might well become real).  If that recording of your mind is complete enough, and it could be, then, you really could go back to an earlier state of yourself. More importantly, a future time tourist could access all the stored records and create an instance of your mind and chat to you and chat and interact with you from the future. This would allow future historians to do history better. Well, that’s the basic version. Our thought experiment version needs to go a bit further than that. Let’s call it the deluxe version.

If you implement the deluxe version, then minds run almost entirely on the machine world platform, and are hosted there with frequent restore points. The current state of the system is an interactive result of real-time running of all the minds held in cyberspace across the whole stored timeline. For those minds running on the deluxe version platform, there isn’t any other reality. That’s what makes up those future humans and AIs on it. Once you join the system, you can enjoy all of the benefits above and many more.

You could actually change old records and use the machines to ripple the full system-wide consequences all the way through the timeline to whenever your future today is. It would allow you to go back to visit your former self and do some editing, wouldn’t it? And in this deluxe version, the edits you make would ripple through into your later self. That’s what you get when you migrate the human mind from the Mk1 human brain platform into the machine world platform. It becomes endlessly replicable and editable. In this deluxe version, the future world really could be altered by editing the past. You may reasonably ask why we would allow any moron to allow that to be built, but that won’t affect the theoretical ability to travel in time through cyberspace.

It is very easy to see how such a system allows you to chat with someone in the past. What is less obvious, and what my excuse for a brain missed first time round, is that it also lets you travel forwards in time. How, you may reasonably ask, can you access and edit records that don’t exist yet? Well, think of it from the other direction. Someone in the future can restore any previous instance of you from any time point and talk to them, even edit them. They could do that all in some sort of time-play sandbox to save money and avoid quite a few social issues, or they could restore you fully to their time, and since the reality is just real-time emulation all rippled through nicely by the machine platform, you would suddenly appear in the future and become part of that future world. You could wander around in a future android body and do physical things in that future physical world just as if you’d always lived there. Your future self would feel they have travelled in time. But a key factor here is that it could be your future self that makes it happen. You could make a request in 2075 to your future self to bring you to the future in 2150. When 2150 arrives, you see (or might even remember) the request, you go into the archives, and you restore your old 2075 self to 2150, then you instruct deletion of all the records between 2075 and 2150 and then you push the big red button. The system runs all the changes and effects through the timeline, and the result is that you disappear in 2075, and suddenly reappear in 2150.

There would be backups of the alternative timeline, but the official and effective system reality would be that you travelled from 2075 to 2150. That will be the reality running on the deluxe system. Any other realities are just backups and records on a database. Now,so far it’s a one way trip, far better if you can have a quick trip to the future and come back. So, you’re in 2150, suppose you want to go back again. You’ve been around a while and don’t like the new music or the food or something. So before you go, you do the usual time mischief. You collect lots of really useful data about how all the latest tech works, buy the almanacs of who wins what, just like in Back to the Future, just in case the system has bugs that let you use them, and you tweak the dials again. You set the destination to 2075 and hit the big red button. The system writes your new future-wise self over your original 2075 entry, keeping a suitable backup of course. The entry used by the deluxe system is whatever is written in its working record, and that is the you that went to 2150 and back. Any other realities are just backups. So, the system ripples it all through the timeline. You start the day in 2075, have a quick trip for a week’s holiday in 2150, and then return a few minutes later. Your 2075 self will have experienced a trip to 2150 and come back, complete with all the useful data about the 2150 world. If you don’t mess with anything else, you will remember that trip until 2150, at which time you’ll grab a few friends and chat about the first time you ever did time travel.

All of the above is feasible theoretically, and none of it violates any known physics. The universe won’t collapse in a causality paradox bubble rift if you do it, no need to send for Dr Who. That doesn’t mean it isn’t without issues. It still creates a lot of the time travel issues we are so familiar with from sci-fi. But this one isn’t sci-fi – we could build it, and we could get the crowd-funding to make it real by 2075. Don’t get too excited yet though.

You could have gone further into the future than 2150 too, but there is a limit. You can only go as far as there exists a continuous record from where you are. You basically need a road that goes all the way there. If some future authority bans time travel or changes to an incompatible system, that represents a wall you can’t pass through. An even later authority could only remove that wall under certain circumstances, and only if they have the complete records, and the earlier authority might have stopped storing them or even deleted earlier ones and that would ruin any chances of doing it properly.

So, having established that it is possible, we have to ask the more serious question: how real is this time travel? Is it just a cyberspace trick with no impact on the real world? Well, in this scenario, your 2075 mind runs on the deluxe system using its 2075 record. But which one, the old one or the edited one? The edited one of course. The old version is overwritten and ceases to exist except as a backup. There remains no reality except the one you did your time travel trip in. Your time trip is real. But let’s ask a few choice questions, because reality can turn out to be just an illusion sometimes.

So, when you get home to 2075, you can print off your 2150 almanac and brag about all the new technologies you just invented from 2150. Yes?

Yes… if you implement the deluxe version.

Is there a causality paradox?

No.

Will the world end?

No.

But you just short-circuited technology development from 2075 to 2150?

Yes.

So you can do real time travel from 2075? You’ll suddenly vanish from 2075, spend some time in 2150, and later reappear in 2075?

Yes, if you implement the deluxe version.

Well, what happens in 2150?

You’ll do all the pushing red button stuff and have a party with your friends to remember your first time trip. If you set the times right, you could even invite your old self from 2075 as a guest and wave goodbye as you* goes back to 2075.

Or you* could stay in 2150 and there’d be two of you from then on?

Yes

OK, this sounds great fun.  So when can we build this super-duper deluxe version that let’s you time travel from 2075 to 2150 and go back again.

2150

And what happens to me between 2075 and 2150 while I wait for it to be built?

Well, you invest in the deluxe version, connect into the system, and it starts recording all its subscribers’ minds from then on, and you carry on enjoying life until 2150 arrives. Then you can travel from 2075 to 2150, retrospectively.

Retrospectively?

Well, you can travel from 2075 to whatever date in the future the deluxe system still exists. And your 2075 self will fully experience it as time travel. It won’t feel retrospective.

But you have to wait till that date before you can go there?

Yes. But you won’t remember having to wait, all the records of that will be wiped, you’ll just vanish in 2075 and reappear in 2150 or whenever.

What *insert string of chosen expletives here* use is that?

Erm…. Well…. You will still have enjoyed a nice life from 2075 to 2150 before it’s deleted and replaced.

But I won’t remember that will I?

No. But you won’t remember it when you’re dead either.

So I can only do this sort of time travel by having myself wiped off the system for all the years in between after I’ve done it? So the best way of doing that is not to bother with all the effort of living through all those years since they’re going to be deleted anyway and save all the memory and processing by just hibernation in the archives till that date arrives? So I’ll really vanish in 2075 and be restored in 2150 and feel it as time travel? And there won’t be any messy database records to clean up in between, and it will all be nice and environmentally friendly? And not having to run all those people years that would later be deleted will reduce storage and processing costs and system implementation costs dramatically?

Exactly!

OK, sounds a bit better again. But it’s still a fancy cyberspace hibernation scheme really isn’t it?

Well, you can travel back and forth through time as much as you like and socialize with anyone from any time zone and live in any time period. Some people from 2150 might prefer to live in 2075 and some from 2075 prefer to live in 2150. Everyone can choose when they live or just roam freely through the entire time period. A bit like that episode of Star Trek TOS where they all got sent through a portal to different places and times and mixed with societies made of others who had come the same way. You could do that. A bit like a glorified highly immersive computer game.

But what about gambling and using almanacs from the future? And inventing stuff in 2075 that isn’t really invented till 2150?

All the knowledge and data from 2150 will be there in the 2075 system so you won’t have anything new and gambling won’t be a viable industry. But it won’t be actually there until 2150. So the 2075 database will be a retrospective singularity where all of the future knowledge suddenly appears.

Isn’t that a rift in the time-space continuum, letting all the future weapons and political activists and terrorists and their plans through from 2150 to 2075? And Daleks? Some idiot will build one just for the hell of it. They’ll come through the rift too won’t they. And Cyberpersons?

It will not be without technical difficulties. And anyway, they can’t do any actual damage outside the system.

But these minds running in the system will be connected to android bodies or humans outside it. Their minds can time travel through cyberspace. Can’t they do anything nasty?

No, they can only send their minds back and connect to stuff within the system. Any androids and bodies could only be inhabited by first generation minds that belong to that physical time. They can only make use of androids or other body sharing stuff when they travel forwards through time, because it is their chosen future date where the android lives and they can arrange that. On a journey backwards, they can only change stuff running in the system.

 And that’s what stops it violating physics?

Yes

So let’s get this straight. This whole thing is great for extending your mind into cyberspace, sharing bodies, swapping personalities, changing gender or age, sharing consciousness and  some other things. But time travel is only possible for your mind that is supported exclusively in the system. And only that bit in the system can time travel. And your actual 2075 body can’t feel the effect at all or do anything about it? So it’s really another you that this all happens to and you start diverging from your other cyber-self the moment you connect. A replica of you enjoys all the benefits but it thinks it is you and feels like you and essentially is you, but not in the real world. And the original you carries on in parallel.

Correct. It is a big cyberspace bubble created over time with continuous timeline emulation, that only lets you time travel and interact within the bubble. Like an alternative universe, and you can travel in time in it. But it can only interact with the physical universe in real time at the furthermost frontier of the bubble. A frontier that moves into the future at the same speed as the rest of the local space-time continuum and doesn’t cause any physics problems or real time paradoxes outside of the system.

So it’s not REAL time travel. It’s just a sort of cyber-sandbox, albeit one that will be good fun and still worth building.

You can time travel in the parallel universe that you make in cyberspace. But it will be real within that universe. Forwards physical time travel is additionally possible in the physical universe if you migrate your mind totally into cyberspace, e.g. when you die, so you can live electronically, and even then it is really just a fancy form of hibernation. And if you travel back in time in the system, you won’t be able to interact with the physical stuff in the past, only what is running on the system. As long as you accept those limitations, you can travel in time after 2075 and live in any period supported after that.

Why do all the good things only ever happen in another universe?

I don’t know.

No physics or mathematics has knowingly been harmed during this thought experiment. No responsibility is accepted for any time-space rifts created as a result of analytical error.

 

 

Time – The final frontier. Maybe

It is very risky naming the final frontier. A frontier is just the far edge of where we’ve got to.

Technology has a habit of opening new doors to new frontiers so it is a fast way of losing face. When Star Trek named space as the final frontier, it was thought to be so. We’d go off into space and keep discovering new worlds, new civilizations, long after we’ve mapped the ocean floor. Space will keep us busy for a while. In thousands of years we may have gone beyond even our own galaxy if we’ve developed faster than light travel somehow, but that just takes us to more space. It’s big, and maybe we’ll never ever get to explore all of it, but it is just a physical space with physical things in it. We can imagine more than just physical things. That means there is stuff to explore beyond space, so space isn’t the final frontier.

So… not space. Not black holes or other galaxies.

Certainly not the ocean floor, however fashionable that might be to claim. We’ll have mapped that in details long before the rest of space. Not the centre of the Earth, for the same reason.

How about cyberspace? Cyberspace physically includes all the memory in all our computers, but also the imaginary spaces that are represented in it. The entire physical universe could be simulated as just a tiny bit of cyberspace, since it only needs to be rendered when someone looks at it. All the computer game environments and virtual shops are part of it too. The cyberspace tree doesn’t have to make a sound unless someone is there to hear it, but it could. The memory in computers is limited, but the cyberspace limits come from imagination of those building or exploring it. It is sort of infinite, but really its outer limits are just a function of our minds.

Games? Dreams? Human Imagination? Love? All very new agey and sickly sweet, but no. Just like cyberspace, these are also all just different products of the human mind, so all of these can be replaced by ‘the human mind’ as a frontier. I’m still not convinced that is the final one though. Even if we extend that to greatly AI-enhanced future human mind, it still won’t be the final frontier. When we AI-enhance ourselves, and connect to the smart AIs too, we have a sort of global consciousness, linking everyone’s minds together as far as each allows. That’s a bigger frontier, since the individual minds and AIs add up to more cooperative capability than they can achieve individually. The frontier is getting bigger and more interesting. You could explore other people directly, share and meld with them. Fun, but still not the final frontier.

Time adds another dimension. We can’t do physical time travel, and even if we can do so in physics labs with tiny particles for tiny time periods, that won’t necessarily translate into a practical time machine to travel in the physical world. We can time travel in cyberspace though, as I explained in

https://timeguide.wordpress.com/2012/10/25/the-future-of-time-travel-cheat/

and when our minds are fully networked and everything is recorded, you’ll be able to travel back in time and genuinely interact with people in the past, back to the point where the recording started. You would also be able to travel forwards in time as far as the recording stops and future laws allow (I didn’t fully realise that when I wrote my time travel blog, so I ought to update it, soon). You’d be able to inhabit other peoples’ bodies, share their minds, share consciousness and feelings and emotions and thoughts. The frontier suddenly jumps out a lot once we start that recording, because you can go into the future as far as is continuously permitted. Going into that future allows you to get hold of all the future technologies and bring them back home, short circuiting the future, as long as time police don’t stop you. No, I’m not nuts – if you record everyone’s minds continuously, you can time travel into the future using cyberspace, and the effects extend beyond cyberspace into the real world you inhabit, so although it is certainly a cheat, it is effectively real time travel, backwards and forwards. It needs some security sorted out on warfare, banking and investments, procreation, gambling and so on, as well as lot of other causality issues, but to quote from Back to the Future: ‘What the hell?’ [IMPORTANT EDIT: in my following blog, I revise this a bit and conclude that although time travel to the future in this system lets you do pretty much what you want outside the system, time travel to the past only lets you interact with people and other things supported within the system platform, not the physical universe outside it. This does limit the scope for mischief.]

So, time travel in fully networked fully AI-enhanced cosmically-connected cyberspace/dream-space/imagination/love/games would be a bigger and later frontier. It lets you travel far into the future and so it notionally includes any frontiers invented and included by then. Is it the final one though? Well, there could be some frontiers discovered after the time travel windows are closed. They’d be even finaller, so I won’t bet on it.
