Optical computing

A few nights ago I was thinking about the optical fibre memories that we were designing in the late 1980s in BT. The idea was simple. You transmit data into an optical fibre, and if the data rate is high you can squeeze lots of data into a manageable length. Back then the speed of light in fibre was about 5 microseconds per km of fibre, so 1000km of fibre, at a data rate of 2Gb/s would hold 10Mbits of data, per wavelength, so if you can multiplex 2 million wavelengths, you’d store 20Tbits of data. You could maintain the data by using a repeater to repeat the data as it reaches one end into the other, or modify it at that point simply by changing what you re-transmit. That was all theory then, because the latest ‘hero’ experiments were only just starting to demonstrate the feasibility of such long lengths, such high density WDM and such data rates.

Nowadays, that’s ancient history of course, but we also have many new types of fibre, such as hollow fibre with various shaped pores and various dopings to allow a range of effects. And that’s where using it for computing comes in.

If optical fibre is designed for this purpose, with optimal variable refractive index designed to facilitate and maximise non-linear effects, then the photons in one data stream on one wavelength could have enough effects of photons in another stream to be used for computational interaction. Computers don’t have to be digital of course, so the effects don’t have to be huge. Analog computing has many uses, and analog interactions could certainly work, while digital ones might work, and hybrid digital/analog computing may also be feasible. Then it gets fun!

Some of the data streams could be programs. Around that time, I was designing protocols with smart packets that contained executable code, as well as other packets that could hold analog or digital data or any mix. We later called the smart packets ANTs – autonomous network telephers, a contrived term if ever there was one, but we wanted to call them ants badly. They would scurry around the network doing a wide range of jobs, using a range of biomimetic and basic physics techniques to work like ant colonies and achieve complex tasks using simple means.

If some of these smart packets or ANTs are running along a fibre, changing the properties as they go to interact with other data transmitting alongside, then ANTs can interact with one another and with any stored data. ANTs could also move forwards or backwards along the fibre by using ‘sidings’ or physical shortcuts, since they can route themselves or each other. Data produced or changed by the interactions could be digital or analog and still work fine, carried on the smart packet structure.

(If you’re interested my protocol was called UNICORN, Universal Carrier for an Optical Residential Network, and used the same architectural principles as my previous Addressed Time Slice invention, compressing analog data by a few percent to fit into a packet, with a digital address and header, or allowing any digital data rate or structure in a payload while keeping the same header specs for easy routing. That system was invented (in 1988) for the late 1990s when basic domestic broadband rate should have been 625Mbit/s or more, but we expected to be at 2Gbit/s or even 20Gbit/s soon after that in the early 2000s, and the benefit as that we wouldn’t have to change the network switching because the header overheads would still only be a few percent of total time. None of that happened because of government interference in the telecoms industry regulation that strongly disincentivised its development, and even today, 625Mbit/s ‘basic rate’ access is still a dream, let alone 20Gbit/s.)

Such a system would be feasible. Shortcuts and sidings are easy to arrange. The protocols would work fine. Non-linear effects are already well known and diverse. If it were only used for digital computing, it would have little advantage over conventional computers. With data stored on long fibre lengths, external interactions would be limited, with long latency. However, it does present a range of potentials for use with external sensors directly interacting with data streams and ANTs to accomplish some tasks associated with modern AI. It ought to be possible to use these techniques to build the adaptive analog neural networks that we’ve known are the best hope of achieving strong AI since Hans Moravek’s insight, coincidentally also around that time. The non-linear effects even enable ideal mechanisms for implementing emotions, biasing the computation in particular directions via intensity of certain wavelengths of light in much the same way as chemical hormones and neurotransmitters interact with our own neurons. Implementing up to 2 million different emotions at once is feasible.

So there’s a whole mineful of architectures, tools and techniques waiting to be explored and mined by smart young minds in the IT industry, using custom non-linear optical fibres for optical AI.

AI could use killer drone swarms to attack people while taking out networks

In 1987 I discovered a whole class of security attacks that could knock out networks, which I called correlated traffic attacks, creating particular patterns of data packet arrivals from particular sources at particular times or intervals. We simulated two examples to successfully verify the problem. One example was protocol resonance. I demonstrated that it was possible to push a system into a gross overload state with a single call, by spacing the packets precise intervals apart. Their arrival caused a strong resonance in the bandwidth allocation algorithms and the result was that network capacity was instantaneously reduced by around 70%. Another example was information waves, whereby a single piece of information appearing at a particular point could, by its interaction with particular apps on mobile devices (the assumption was financially relevant data that would trigger AI on the devices to start requesting voluminous data, triggering a highly correlated wave of responses, using up bandwidth and throwing the network into overload, very likely crashing due to initiation of rarely used software. When calls couldn’t get through, the devices would wait until the network recovered, then they would all simultaneously detect recovery and simultaneously try again, killing the net again, and again, until people were asked to turn  their devices off and on again, thereby bringing randomness back into the system. Both of these examples could knock out certain kinds of networks, but they are just two of an infinite set of possibilities in the correlated traffic attack class.

Adversarial AI pits one AI against another, trying things at random or making small modifications until a particular situation is achieved, such as the second AI accepting an image is acceptable. It is possible, though I don’t believe it has been achieved yet, to use the technique to simulate a wide range of correlated traffic situations, seeing which ones achieve network resonance or overloads, which trigger particular desired responses from network management or control systems, via interactions with the network and its protocols, commonly resident apps on mobile devices or computer operating systems.

Activists and researchers are already well aware that adversarial AI can be used to find vulnerabilities in face recognition systems and thereby prevent recognition, or to deceive autonomous car AI into seeing fantasy objects or not seeing real ones. As Noel Sharkey, the robotics expert, has been tweeting today, it will be possible to use adversarial AI to corrupt recognition systems used by killer drones, potentially to cause them to attack their controllers or innocents instead of their intended targets. I have to agree with him. But linking that corruption to the whole extended field of correlated traffic attacks extends the range of mechanisms that can be used greatly. It will be possible to exploit highly obscured interactions between network physical architecture, protocols and operating systems, network management, app interactions, and the entire sensor/IoT ecosystem, as well as software and AI systems using it. It is impossible to check all possible interactions, so no absolute defence is possible, but adversarial AI with enough compute power could randomly explore across these multiple dimensions, stumble across regions of vulnerability and drill down until grand vulnerabilities are found.

This could further be linked to apps used as highly invisible Trojans, offering high attractiveness to users with no apparent side effects, quietly gathering data to help identify potential targets, and simply waiting for a particular situation or command before signalling to the attacking system.

A future activist or terrorist group or rogue state could use such tools to make a multidimensional attack. It could initiate an attack, using its own apps to identify and locate targets, control large swarms of killer drones or robots to attack them, simultaneously executing a cyberattack that knocks out selected parts of the network, crashing or killing computers and infrastructure. The vast bulk of this could be developed, tested and refined offline, using simulation and adversarial AI approaches to discover vulnerabilities and optimise exploits.

There is already debate about killer drones, mainly whether we should permit them and in what circumstances, but activists and rogue states won’t care about rules. Millions of engineers are technically able to build such things and some are not on your side. It is reasonable to expect that freely available AI tools will be used in such ways, using their intelligence to design, refine, initiate and control attacks using killer drones, robots and self-driving cars to harm us, while corrupting systems and infrastructure that protect us.

Worrying, especially since the capability is arriving just as everyone is starting to consider civil war.

 

 

Will urbanization continue or will we soon reach peak city?

For a long time, people have been moving from countryside into cities. The conventional futurist assumption is that this trend will continue, with many mega-cities, some with mega-buildings. I’ve consulted occasionally on future buildings and future cities from a technological angle, but I’ve never really challenged the assumption that urbanization will continue. It’s always good  to challenge our assumptions occasionally, as things can change quite rapidly.

There are forces in both directions. Let’s list those that support urbanisation first.

People are gregarious. They enjoy being with other people. They enjoy eating out and having coffees with friends. They like to go shopping. They enjoy cinemas and theatre and art galleries and museums. They still have workplaces. Many people want to live close to these facilities, where public transport is available or driving times are relatively short. There are exceptions of course, but these still generally apply.

Even though many people can and do work from home sometimes, most of them still go to work, where they actually meet colleagues, and this provides much-valued social contact, and in spite of recent social trends, still provides opportunities to meet new friends and partners. Similarly, they can and do talk to friends via social media or video calls, but still enjoy getting together for real.

Increasing population produces extra pressure on the environment, and governments often try to minimize it by restricting building on green field land. Developers are strongly encouraged to build on brown field sites as far as possible.

Now the case against.

Truly Immersive Interaction

Talking on the phone, even to a tiny video image, is less emotionally rich than being there with someone. It’s fine for chats in between physical meetings of course, but the need for richer interaction still requires ‘being there’. Augmented reality will soon bring headsets that provide high quality 3D life-sized images of the person, and some virtual reality kit will even allow analogs of physical interaction via smart gloves or body suits, making social comms a bit better. Further down the road, active skin will enable direct interaction with the peripheral nervous system to produce exactly the same nerve signals as an actual hug or handshake or kiss, while active contact lenses will provide the same resolution as your retina wherever you gaze. The long term is therefore communication which has the other person effectively right there with you, fully 3D, fully rendered to the capability of your eyes, so you won’t be able to tell they aren’t. If you shake hands or hug or kiss, you’ll feel it just the same as if they were there too. You will still know they are not actually there, so it will never be quite as emotionally rich as if they were, but it can get pretty close. Close enough perhaps that it won’t really matter to most people most of the time that it’s virtual.

In the same long term, many AIs will have highly convincing personalities, some will even have genuine emotions and be fully conscious. I blogged recently on how that might happen if you don’t believe it’s possible:

https://timeguide.wordpress.com/2018/06/04/biomimetic-insights-for-machine-consciousness/

None of the technology required for this is far away, and I believe a large IT company could produce conscious machines with almost human-level AI within a couple of years of starting the project. It won’t happen until they do, but when one starts trying seriously to do it, it really won’t be long. That means that as well as getting rich emotional interaction from other humans via networks, we’ll also get lots from AI, either in our homes, or on the cloud, and some will be in robots in our homes too.

This adds up to a strong reduction in the need to live in a city for social reasons.

Going to cinemas, theatre, shopping etc will also all benefit from this truly immersive interaction. As well as that, activities that already take place in the home, such as gaming will also advance greatly into more emotionally and sensory intensive experiences, along with much enhanced virtual tourism and virtual world tourism, virtual clubbing & pubbing, which barely even exist yet but could become major activities in the future.

Socially inclusive self-driving cars

Some people have very little social interaction because they can’t drive and don’t live close to public transport stops. In some rural areas, buses may only pass a stop once a week. Our primitive 20th century public transport systems thus unforgivably exclude a great many people from social inclusion, even though the technology needed to solve that has existed for many years.  Leftist value systems that much prefer people who live in towns or close to frequent public transport over everyone else must take a lot of the blame for the current epidemic of loneliness. It is unreasonable to expect those value systems to be replaced by more humane and equitable ones any time soon, but thankfully self-driving cars will bypass politicians and bureaucrats and provide transport for everyone. The ‘little old lady’ who can’t walk half a mile to wait 20 minutes in freezing rain for an uncomfortable bus can instead just ask her AI to order a car and it will pick her up at her front door and take her to exactly where she wants to go, then do the same for her return home whenever she wants. Once private sector firms like Uber provide cheap self-driving cars, they will be quickly followed by other companies, and later by public transport providers. Redundant buses may finally become extinct, replaced by better socially inclusive transport, large fleets of self-driving or driverless vehicles. People will be able to live anywhere and still be involved in society. As attendance at social events improves, so they will become feasible even in small communities, so there will be less need to go into a town to find one. Even political involvement might increase. Loneliness will decline as social involvement increases, and we’ll see many other social problems decline too.

Distribution drones

We hear a lot about upcoming redundancy caused by AI, but far less about the upside. AI might mean someone is no longer needed in an office, but it also makes it easier to set up a company and run it, taking what used to be just a hobby and making it into a small business. Much of the everyday admin and logistics can be automated Many who would never describe themselves as entrepreneurs might soon be making things and selling them from home and this AI-enabled home commerce will bring in the craft society. One of the big problems is getting a product to the customer. Postal services and couriers are usually expensive and very likely to lose or damage items. Protecting objects from such damage may require much time and expense packing it. Even if objects are delivered, there may be potential fraud with no-payers. Instead of this antiquated inefficient and expensive system, drone delivery could collect an object and take it to a local customer with minimal hassle and expense. Block-chain enables smart contracts that can be created and managed by AI and can directly link delivery to payment, with fully verified interaction video if necessary. If one happens, the other happens. A customer might return a damaged object, but at least can’t keep it and deny receipt. Longer distance delivery can still use cheap drone pickup to take packages to local logistics centers in smart crates with fully block-chained g-force and location detectors that can prove exactly who damaged it and where. Drones could be of any size, and of course self-driving cars or pods can easily fill the role too if smaller autonomous drones are inappropriate.

Better 3D printing technology will help to accelerate the craft economy, making it easier to do crafts by upskilling people and filling in some of their skill gaps. Someone with visual creativity but low manual skill might benefit greatly from AI model creation and 3D printer manufacture, followed by further AI assistance in marketing, selling and distribution. 3D printing might also reduce the need to go to town to buy some things.

Less shopping in high street

This is already obvious. Online shopping will continue to become a more personalized and satisfying experience, smarter, with faster delivery and easier returns, while high street decline accelerates. Every new wave of technology makes online better, and high street stores seem unable or unwilling to compete, in spite of my wonderful ‘6s guide’:

https://timeguide.wordpress.com/2013/01/16/the-future-of-high-street-survival-the-6s-guide/

Those that are more agile still suffer decline of shopper numbers as the big stores fail to attract them so even smart stores will find it harder to survive.

Improving agriculture

Farming technology has doubled the amount of food production per hectare in the last few decades. That may happen again by mid-century. Meanwhile, the trend is towards higher vegetable and lower meat consumption. Even with an increased population, less land will be needed to grow our food. As well as reducing the need to protect green belts, that will also allow some of our countryside to be put under better environmental stewardship programs, returning much of it to managed nature. What countryside we have will be healthier and prettier, and people will be drawn to it more.

Improving social engineering

Some objections to green-field building can be reduced by making better use of available land. Large numbers of new homes are needed and they will certainly need some green field to be used, but given the factors already listed above, a larger number of smaller communities might be better approach. Amazingly, in spite of decades of dating technology proving that people can be matched up easily using AI, there is still no obvious use of similar technology to establish new communities by blending together people who are likely to form effective communities. Surely it must be feasible to advertise a new community building program that wants certain kinds of people in it – even an Australian style points system might work sometimes. Unless sociologists have done nothing for the past decades, they must surely know what types of people work well together by now? If the right people live close to each other, social involvement will be high, loneliness low, health improved, care costs minimized, the need for longer distance travel reduced and environmental impact minimized. How hard can it be?

Improving building technology such as 3D printing and robotics will allow more rapid construction, so that when people are ready and willing to move, property suited to them can be available soon.

Lifestyle changes also mean that homes don’t need to be as big. A phone today does what used to need half a living room of technology and space. With wall-hung displays and augmented reality, decor can be partly virtual, and even a 450 sq ft apartment is fine as a starter place, half as big as was needed a few decades ago, and that could be 3D printed and kitted out in a few days.

Even demographic changes favor smaller communities. As wealth increases, people have smaller families, i.e fewer kids. That means fewer years doing the school run, so less travel, less need to be in a town. Smaller schools in smaller communities can still access specialist lessons via the net.

Increasing wealth also encourages and enables people to a higher quality of life. People who used to live in a crowded city street might prefer a more peaceful and spacious existence in a more rural setting and will increasingly be able to afford to move. Short term millennial frustrations with property prices won’t last, as typical 2.5% annual growth more than doubles wealth by 2050 (though automation and its assorted consequences will impact on the distribution of that wealth).

Off-grid technology

Whereas one of the main reasons to live in urban areas was easy access to telecomms, energy and water supply and sewerage infrastructure, all of these can now be achieved off-grid. Mobile networks provide even broadband access to networks. Solar or wind provide easy energy supply. Water can be harvested out of the air even in arid areas (http://www.dailymail.co.uk/sciencetech/article-5840997/The-solar-powered-humidity-harvester-suck-drinkable-water-AIR.html) and human and pet waste can be used as biomass for energy supply too, leaving fertilizer as residue.

There are also huge reasons that people won’t want to live in cities, and they will also cause deurbansisation.

The biggest by far in the problem of epidemics. As antibiotic resistance increases, disease will be a bigger problem. We may find good antibiotics alternatives but we may not. If not, then we may see some large cities where disease runs rampant and kills hundreds of thousands of people, perhaps even millions. Many scientists have listed pandemics among their top ten threats facing humanity. Obviously, being in a large city will incur a higher risk of becoming a victim, so once one or two incidents have occurred, many people will look for options to leave cities everywhere. Linked to this is bioterrorism, where the disease is deliberate, perhaps created in a garden shed by someone who learned the craft in one of today’s bio-hacking clubs. Disease might be aimed at a particular race, gender or lifestyle group or it may simply be designed to be as contagious and lethal as possible to everyone.

I’m still not saying we won’t have lots of people living in cities. I am saying that more people will feel less need to live in cities and will instead be able to find a small community where they can be happier in the countryside. Consequently, many will move out of cities, back to more rural living in smaller, friendlier communities that improving technology makes even more effective.

Urbanization will slow down, and may well go into reverse. We may reach peak city soon.

 

 

Why superhumans are inevitable, and what else comes in the box

Do we have any real choice in the matter of making  super-humans? 20 years ago, I estimated 2005 as the point of no return, and nothing since then has changed my mind on that date. By my reckoning, we are already inevitably committed to designer babies, ebaybies, super-soldiers and super-smart autonomous weapons, direct brain-machine links, electronic immortality, new human races, population explosion, inter-species conflicts and wars with massively powerful weaponry, superhuman conscious AI, smart bacteria, and the only real control we have is relatively minor adjustments on timings. As I was discussing yesterday, the technology potential for this is vast and very exciting, nothing less than a genuine techno-utopia if we use the technologies wisely, but optimum potential doesn’t automatically become reality, and achieving a good outcome is unlikely if many barriers are put in its way.

In my estimation, we have already started the countdown to this group of interconnected technologies – we will very likely get all of them, and we must get ready for the decisions and impacts ahead. At the moment, our society is a small child about to open its super-high-tech xmas presents while fighting with its siblings. Those presents will give phenomenal power far beyond the comprehension of the child or its emotional maturity to equip it to deal with the decisions safely. Our leaders have already squandered decades of valuable preparation time by ignoring the big issues to focus on trivial ones. It is not too late to achieve a good ending, but it won’t happen by accident and we do need to make preparations to avoid pretty big problems.

Both hard and soft warfare – the sword and the pen, already use rapidly advancing AI, and the problems are already running ahead of what the owners intended.

Facebook, Twitter, Instagram and other media giants all have lots of smart people and presumably they mean well, but if so, they have certainly been naive. They maybe hoped to eliminate loneliness, inequality, and poverty and create a loving interconnected global society with global peace, but instead created fake news, social division and conflict and election interference. More likely they didn’t intend either outcome, they just wanted to make money and that took priority over due care and attention..

Miniaturising swarming smart-drones are already the subjects of a new arms race that will deliver almost un-killable machine adversaries by 2050. AI separately is in other arms races to make super-smart AI and super-smart soldiers. This is key to the 2005 point of no return. It was around 2005 that we reached the levels of technology where future AI development all the way to superhuman machine consciousness could be done by individuals, mad scientists or rogue states, even if major powers had banned it. Before 2005, there probably wasn’t quite enough knowledge already on the net to do that. In 2018, lots of agencies have already achieved superiority to humans in niche areas, and other niches will succumb one by one until the whole field of human capability is covered. The first machines to behave in ways not fully understood by humans arrived in the early 1990s; in 2018, neural nets already make lots of decisions at least partly obscured to humans.

This AI development trend will take us to superhuman AI, and it will be able to accelerate development of its own descendants to vastly superhuman AI, fully conscious, with emotions, and its own agendas. That will need humans to protect against being wiped out by superhuman AI. The only three ways we could do that are to either redesign the brain biologically to be far smarter, essentially impossible in the time-frame, to design ways to link our brains to machines, so that we have direct access to the same intelligence as the AIs, so a gulf doesn’t appear and we can remain relatively safe, or pray for super-smart aliens to come to our help, not the best prospect.

Therefore we will have no choice but to make direct brain links to super-smart AI. Otherwise we risk extinction. It is that simple. We have some idea how to do that – nanotech devices inside the brain linking to each and every synapse that can relay electrical signals either way, a difficult but not impossible engineering problem. Best guesses for time-frame fall in the 2045-2050 range for a fully working link that not only relays signals between your organic brain and an IT replica, but by doing so essentially makes external IT just another part of your brain. That conveys some of the other technology gifts of electronic immortality, new varieties of humans, smart bacteria (which will be created during the development path to this link) along with human-variant population explosion, especially in cyberspace, with androids as their physical front end, and the inevitable inter-species conflicts over resources and space – trillions of AI and human-like minds in cyberspace that want to do things in the real world cannot be assumed to be willingly confined just to protect the interests of what they will think of as far lesser species.

Super-smart AI or humans with almost total capability to design whatever synthetic biology is needed to achieve any biological feature will create genetic listings for infinite potential offspring, simulate them, give some of them cyberspace lives, assemble actual embryos for some of them and bring designer babies. Already in 2018, you can pay to get a DNA listing, and blend it in any way you want with the listing of anyone else. It’s already possible to make DNA listings for potential humans and sell them on ebay, hence the term ebaybies. That is perfectly legal, still, but I’ve been writing and lecturing about them since 2004. Today they would just be listings, but we’ll one day have the tech to simulate them, choose ones we like and make them real, even some that were sold as celebrity collector items on ebay. It’s not only too late to start regulating this kind of tech, our leaders aren’t even thinking about it yet.

These technologies are all linked intricately, and their foundations are already in place, with much of the building on those foundations under way. We can’t stop any of these things from happening, they will all come in the same basket. Our leaders are becoming aware of the potential and the potential dangers of the AI positive feedback loop, but at least 15 years too late to do much about it. They have been warned repeatedly and loudly but have focused instead on the minor politics of the day that voters are aware of. The fundamental nature of politics is unlikely to change substantially, so even efforts to slow down the pace of development or to limit areas of impact are likely to be always too little too late. At best, we will be able to slow runaway AI development enough to allow direct brain links to protect against extinction scenarios. But we will not be able to stop it now.

Given inevitability, it’s worth questioning whether there is even any point in trying. Why not just enjoy the ride? Well, the brakes might be broken, but if we can steer the bus expertly enough, it could be exciting and we could come out of it smelling of roses. The weak link is certainly the risk of super-smart AI, whether AI v humans or countries using super-smart AI to fight fiercely for world domination. That risk is alleviated by direct brain linkage, and I’d strongly argue necessitates it, but that brings the other technologies. Even if we decide not to develop it, others will, so one way or another, all these techs will arrive, and our future late century will have this full suite of techs, plus many others of course.

We need as a matter of extreme urgency to fix these silly social media squabbles and over-reactions that are pulling society apart. If we have groups hating each other with access to extremely advanced technology, that can only mean trouble. Tolerance is broken, sanctimony rules, the Inquisition is in progress. We have been offered techno-utopia, but current signs are that most people think techno-hell looks more appetizing and it is their free choice.

AIs of a feather flocking together to create global instability

Hawking and Musk have created a lot of media impact with their warnings about AI, so although terminator scenarios resulting from machine consciousness have been discussed, as have more mundane use of non-conscious autonomous weapon systems, it’s worth noting that I haven’t yet heard them mention one major category of risks from AI – emergence. AI risks have been discussed frequently since the 1970s, and in the 1990s a lot of work was done in the AI community on emergence. Complex emergent patterns of behavior often result from interactions between entities driven by simple algorithms. Genetic algorithms were demonstrated to produce evolution, simple neighbor-interaction rules were derived to illustrate flocking behaviors that make lovely screen saver effects. Cellular automata were played with. In BT we invented ways of self-organizing networks and FPGAs, played with mechanism that could be used for evolution and consciousness, demonstrated managing networks via ANTs – autonomous network telephers, using smart packets that would run up and down wires sorting things out all by themselves. In 1987 discovered a whole class of ways of bringing down networks via network resonance, information waves and their much larger class of correlated traffic – still unexploited by hackers apart from simple DOS attacks. These ideas have slowly evolved since, and some have made it into industry or hacker toolkits, but we don’t seem to be joining the dots as far as risks go.

I read an amusing article this morning by an ex-motoring-editor who was declined insurance because the AI systems used by insurance companies had labelled him as high risk because he maybe associated with people like Clarkson. Actually, he had no idea why, but that was his broker’s theory of how it might have happened. It’s a good article, well written and covers quite a few of the dangers of allowing computers to take control.

http://www.dailymail.co.uk/sciencetech/article-5310031/Evidence-robots-acquiring-racial-class-prejudices.html

The article suggested how AIs in different companies might all come to similar conclusions about people or places or trends or patterns in a nice tidy positive feedback loop. That’s exactly the sort of thing that can drive information waves, which I demonstrated in 1987 can bring down an entire network in less than 3 milliseconds, in such a way that it would continue to crash many times when restarted. That isn’t intended by the algorithms, which individually ought to make good decisions, but when interacting with one another, create the emergent phenomenon.  Automated dealing systems are already pretty well understood in this regard and mechanisms prevent frequent stock market collapses, but that is only one specific type of behavior in one industry that is protected. There do not seem to be any industry-wide mechanisms to prevent the rest of this infinite class of problems from affecting any or all of the rest, simultaneously.

As we create ever more deep learning neural networks, that essentially teach themselves from huge data pools, human understanding of their ‘mindsets’ decreases. They make decisions using algorithms that are understood at a code level, but the massive matrix of derived knowledge they create from all the data they receive becomes highly opaque. Often, even usually, nobody quite knows how a decision is made. That’s bad enough in a standalone system, but when many such systems are connected, produced and owned and run by diverse companies with diverse thinking, the scope for destructive forms of emergence increases geometrically.

One result could be gridlock. Systems fed with a single new piece of data could crash. My 3 millisecond result in 1987 would still stand since network latency is the prime limiter. The first AI receives it, alters its mindset accordingly, processes it, makes a decision and interacts with a second AI. This second one might have different ‘prejudice’ so makes its own decision based on different criteria, and refuses to respond the way intended. A 3rd one looks at the 2nd’s decision and takes that as evidence that there might be an issue, and with its risk-averse mindset, also refuse to act, and that inaction spreads through the entire network in milliseconds. Since the 1st AI thinks the data is all fine and it should have gone ahead, it now interprets the inaction of the others as evidence that that type of data is somehow ‘wrong’ so itself refuses to process any further of that type, whether from its own operators or other parts of the system. So it essentially adds its own outputs to the bad feeling and the entire system falls into sulk mode. As one part of infrastructure starts to shut down, that infects other connected parts and our entire IT could fall into sulk mode – entire global infrastructure. Since nobody knows how it all works, or what has caused the shutdown, it might be extremely hard to recover.

Another possible result is a direct information wave, almost certainly a piece of fake news. Imagine our IT world in 5 years time, with all these super-smart AIs super-connected. A piece of fake news says a nuke has just been launched somewhere. Stocks will obviously decline, whatever the circumstances, so as the news spreads, everyone’s AIs will take it on themselves to start selling shares before the inevitable collapse, triggering a collapse, except it won’t because the markets won’t let that happen. BUT… The wave does spread, and all those individual AIs want to dispose of those shares, or at least find out what’s happening, so they all start sending messages to one another, exchanging data, trying to find what’s going on. That’s the information wave. They can’t sell shares of find out, because the network is going into overload, so they try even harder and force it into severe overload. So it falls over. When it comes back online, they all try again, crashing it again, and so on.

Another potential result is smartass AI. There is always some prat somewhere who sees an opportunity to take advantage and ruins if for everyone else by doing something like exploiting a small loophole in the law, or in this case, most likely, a prejudice our smartass AI has discovered in some other AI that means it can be taken advantage of by doing x, y, or z. Since nobody quite knows how any of their AIs are making their decisions because their mindsets ate too big and too complex, it will be very hard to identify what is going on. Some really unusual behavior is corrupting the system because some AI is going rogue somewhere somehow, but which one, where, how?

That one brings us back to fake news. That will very soon infect AI systems with their own varieties of fake news. Complex networks of AIs will have many of the same problems we are seeing in human social networks. An AI could become a troll just the same as a human, deliberately winding others up to generate attention of drive a change of some parameter – any parameter – in its own favour. Activist AIs will happen due to people making them to push human activist causes, but they will also do it all by themselves. Their analysis of the system will sometimes show them that a good way to get a good result is to cause problems elsewhere.

Then there’s climate change, weather, storms, tsunamis. I don’t mean real ones, I mean the system wide result of tiny interactions of tiny waves and currents of data and knowledge in neural nets. Tiny effects in one small part of a system can interact in unforeseen ways with other parts of other systems nearby, creating maybe a breeze, which interacts with breezes in nearby regions to create hurricanes. I think that’s a reasonable analogy. Chaos applies to neural net societies just as it does to climate, and 50 year waves equivalents will cause equivalent havoc in IT.

I won’t go on with more examples, long blogs are awful to read. None of these requires any self-awareness, sentience, consciousness, call it what you will. All of these can easily happen through simple interactions of fairly trivial AI deep learning nets. The level of interconnection already sounds like it may already be becoming vulnerable to such emergence effects. Soon it definitely will be. Musk and Hawking have at least joined the party and they’ll think more and more deeply in coming months. Zuckerberg apparently doesn’t believe in AI threats but now accepts the problems social media is causing. Sorry Zuck, but the kind of AI you’re company is messing with will also be subject to its own kinds of social media issues, not just in its trivial decisions on what to post or block, but actual inter-AI socializing issues. It might not try to eliminate humanity, but if it brings all of our IT to a halt and prevents rapid recovery, we’re still screwed.

 

AI and activism, a Terminator-sized threat targeting you soon

You should be familiar with the Terminator scenario. If you aren’t then you should watch one of the Terminator series of films because you really should be aware of it. But there is another issue related to AI that is arguably as dangerous as the Terminator scenario, far more likely to occur and is a threat in the near term. What’s even more dangerous is that in spite of that, I’ve never read anything about it anywhere yet. It seems to have flown under our collective radar and is already close.

In short, my concern is that AI is likely to become a heavily armed Big Brother. It only requires a few components to come together that are already well in progress. Read this, and if you aren’t scared yet, read it again until you understand it 🙂

Already, social media companies are experimenting with using AI to identify and delete ‘hate’ speech. Various governments have asked them to do this, and since they also get frequent criticism in the media because some hate speech still exists on their platforms, it seems quite reasonable for them to try to control it. AI clearly offers potential to offset the huge numbers of humans otherwise needed to do the task.

Meanwhile, AI is already used very extensively by the same companies to build personal profiles on each of us, mainly for advertising purposes. These profiles are already alarmingly comprehensive, and increasingly capable of cross-linking between our activities across multiple platforms and devices. Latest efforts by Google attempt to link eventual purchases to clicks on ads. It will be just as easy to use similar AI to link our physical movements and activities and future social connections and communications to all such previous real world or networked activity. (Update: Intel intend their self-driving car technology to be part of a mass surveillance net, again, for all the right reasons: http://www.dailymail.co.uk/sciencetech/article-4564480/Self-driving-cars-double-security-cameras.html)

Although necessarily secretive about their activities, government also wants personal profiles on its citizens, always justified by crime and terrorism control. If they can’t do this directly, they can do it via legislation and acquisition of social media or ISP data.

Meanwhile, other experiences with AI chat-bots learning to mimic human behaviors have shown how easily AI can be gamed by human activists, hijacking or biasing learning phases for their own agendas. Chat-bots themselves have become ubiquitous on social media and are often difficult to distinguish from humans. Meanwhile, social media is becoming more and more important throughout everyday life, with provably large impacts in political campaigning and throughout all sorts of activism.

Meanwhile, some companies have already started using social media monitoring to police their own staff, in recruitment, during employment, and sometimes in dismissal or other disciplinary action. Other companies have similarly started monitoring social media activity of people making comments about them or their staff. Some claim to do so only to protect their own staff from online abuse, but there are blurred boundaries between abuse, fair criticism, political difference or simple everyday opinion or banter.

Meanwhile, activists increasingly use social media to force companies to sack a member of staff they disapprove of, or drop a client or supplier.

Meanwhile, end to end encryption technology is ubiquitous. Malware creation tools are easily available.

Meanwhile, successful hacks into large company databases become more and more common.

Linking these various elements of progress together, how long will it be before activists are able to develop standalone AI entities and heavily encrypt them before letting them loose on the net? Not long at all I think.  These AIs would search and police social media, spotting people who conflict with the activist agenda. Occasional hacks of corporate databases will provide names, personal details, contacts. Even without hacks, analysis of publicly available data going back years of everyone’s tweets and other social media entries will provide the lists of people who have ever done or said anything the activists disapprove of.

When identified, they would automatically activate armies of chat-bots, fake news engines and automated email campaigns against them, with coordinated malware attacks directly on the person and indirect attacks by communicating with employers, friends, contacts, government agencies customers and suppliers to do as much damage as possible to the interests of that person.

Just look at the everyday news already about alleged hacks and activities during elections and referendums by other regimes, hackers or pressure groups. Scale that up and realize that the cost of running advanced AI is negligible.

With the very many activist groups around, many driven with extremist zeal, very many people will find themselves in the sights of one or more activist groups. AI will be able to monitor everyone, all the time.  AI will be able to target each of them at the same time to destroy each of their lives, anonymously, highly encrypted, hidden, roaming from server to server to avoid detection and annihilation, once released, impossible to retrieve. The ultimate activist weapon, that carries on the fight even if the activist is locked away.

We know for certain the depths and extent of activism, the huge polarization of society, the increasingly fierce conflict between left and right, between sexes, races, ideologies.

We know about all the nice things AI will give us with cures for cancer, better search engines, automation and economic boom. But actually, will the real future of AI be harnessed to activism? Will deliberate destruction of people’s everyday lives via AI be a real problem that is almost as dangerous as Terminator, but far more feasible and achievable far earlier?

Google v Facebook – which contributes most to humanity?

Please don’t take this too seriously, it’s intended as just a bit of fun. All of it is subjective and just my personal opinion of the two companies.

Google’s old motto of ‘do no evil’ has taken quite a battering over the last few years, but my overall feeling towards them remains somewhat positive overall. Facebook’s reputation has also become muddied somewhat, but I’ve never been an active user and always found it supremely irritating when I’ve visited to change privacy preferences or read a post only available there, so I guess I am less positive towards them. I only ever post to Facebook indirectly via this blog and twitter. On the other hand, both companies do a lot of good too. It is impossible to infer good or bad intent because end results arise from a combination of intent and many facets of competence such as quality of insight, planning, competence, maintenance, response to feedback and many others. So I won’t try to differentiate intent from competence and will just stick to casual amateur observation of the result. In order to facilitate score-keeping of the value of their various acts, I’ll use a scale from very harmful to very beneficial, -10 to +10.

Google (I can’t bring myself to discuss Alphabet) gave us all an enormous gift of saved time, improved productivity and better self-fulfilment by effectively replacing a day in the library with a 5 second online search. We can all do far more and live richer lives as a result. They have continued to build on that since, adding extra features and improved scope. It’s far from perfect, but it is a hell of a lot better than we had before. Score: +10

Searches give Google a huge and growing data pool covering the most intimate details of every aspect of our everyday lives. You sort of trust them not to blackmail you or trash your life, but you know they could. The fact remains that they actually haven’t. It is possible that they might be waiting for the right moment to destroy the world, but it seems unlikely. Taking all our intimate data but choosing not to end the world yet: Score +9

On the other hand, they didn’t do either of those things purely through altruism. We all pay a massive price: advertising. Advertising is like a tax. Almost every time you buy something, part of the price you pay goes to advertisers. I say almost because Futurizon has never paid a penny yet for advertising and yet we have sold lots, and I assume that many other organisations can say the same, but most do advertise, and altogether that siphons a huge amount from our economy. Google takes lots of advertising revenue, but if they didn’t take it, other advertisers would, so I can only give a smallish negative for that: Score -3

That isn’t the only cost though. We all spend very significant time getting rid of ads, wasting time by clicking on them, finding, downloading and configuring ad-blockers to stop them, re-configuring them to get entry to sites that try to stop us from using ad-blockers, and often paying per MB for unsolicited ad downloads to our mobiles. I don’t need to quantify that to give all that a score of -9.

They are still 7 in credit so they can’t moan too much.

Tax? They seem quite good at minimizing their tax contributions, while staying within the letter of the law, while also paying good lawyers to argue what the letter of the law actually says. Well, most of us try at least a bit to avoid paying taxes we don’t have to pay. Google claims to be doing us all a huge favor by casting light on the gaping holes in international tax law that let them do it, much like a mugger nicely shows you the consequences of inadequate police coverage by enthusiastically mugging you. Noting the huge economic problems caused across the world by global corporates paying far less tax than would seem reasonable to the average small-business-owner, I can’t honestly see how this could live comfortably with their do-no evil mantra. Score: -8

On the other hand, if they paid all that tax, we all know governments would cheerfully waste most of it. Instead, Google chooses to do some interesting things with it. They gave us Google Earth, which at least morally cancels out their ‘accidental’ uploading of everyone’s wireless data as their street-view cars went past.They have developed self-driving cars. They have bought and helped develop Deep-mind and their quantum computer. They have done quite a bit for renewable energy. They have spent some on high altitude communications planes supposedly to bring internet to the rural parts of the developing world. When I were a lad, I wanted to be a rich bastard so I could do all that. Now, I watch as the wealthy owners of these big companies do it instead. I am fairly happy with that. I get the results and didn’t have to make the effort. We get less tax, but at least we get some nice toys. Almost cancels. Score +6

They are trying to use their AI to analyse massive data pools of medical records to improve medicine. Score +2

They are also building their databases more while doing that but we don’t yet see the downside. We have to take what they are doing on trust until evidence shows otherwise.

Google has tried and failed at many things that were going to change the world and didn’t, but at least they tried. Most of us don’t even try. Score +2

Oh yes, they bought YouTube, so I should factor that in. Mostly harmless and can be fun. Score: +2

Almost forgot Gmail too. Score +3

I’m done. Total Google contribution to humanity: +14

Well done! Could do even better.

I’ve almost certainly overlooked some big pluses and minuses, but I’ll leave it here for now.

Now Facebook.

It’s obviously a good social network site if you want that sort of thing. It lets people keep in touch with each other, find old friends and make new ones. It lets others advertise their products and services, and others to find or spread news. That’s all well and good and even if I and many other people don’t want it, many others do, so it deserves a good score, even if it isn’t as fantastic as Google’s search, that almost everyone uses, all the time. Score +5

Connected, but separate from simply keeping in touch, is the enormous pleasure value people presumably get from socializing. Not me personally, but ‘people’. Score +8

On the downside: Quite a lot of problems result from people, especially teens, spending too much time on Facebook. I won’t reproduce the results of all the proper academic  studies here, but we’ve all seen various negative reports: people get lower grades in their exams, people get bullied, people become socially competitive – boasting about their successes while other people feel insecure or depressed when others seem to be doing better, or are prettier, or have more friends. Keeping in touch is good, but cutting bits off others’ egos to build your own isn’t. It is hard not to conclude that the negative uses of keeping in touch outweigh the positive ones. Long-lived bad-feelings outweigh short-lived ego-boosts. Score: -8

Within a few years of birth, Facebook evolved from a keeping-in-touch platform to a general purpose mini-web. Many people were using Facebook to do almost everything that others would do on the entire web. Being in a broom cupboard is fine for 5 minutes if you’re playing hide and seek, but it is not desirable as a permanent state. Still, it is optional, so isn’t that bad per se: Score: -3

In the last 2 or 3 years, it has evolved further, albeit probably unintentionally, to become a political bubble, as has become very obvious in Brexit and the US Presidential Election, though it was already apparent well before those. Facebook may not have caused the increasing divide we are seeing between left and right, across the whole of the West, but it amplifies it. Again, I am not implying any intent, just observing the result. Most people follow people and media that echoes their own value judgments. They prefer resonance to dissonance. They prefer to have their views reaffirmed than to be disputed. When people find a comfortable bubble where they feel they belong, and stay there, it is easy for tribalism to take root and flourish, with demonization of the other not far behind. We are now seeing that in our bathtub society, with two extremes and a rapidly shallowing in-between that was not long ago the vast majority. Facebook didn’t create human nature; rather, it is a victim of it, but nonetheless it provides a near-monopoly social network that facilitates such political bubbles and their isolation while doing far too little to encourage integration in spite of its plentiful resources. Dangerous and Not Good. Score -10

On building databases of details of our innermost lives, managing not to use the data to destroy our lives but instead only using it to sell ads, they compare with Google. I’ll score that the same total for the same reasons: Net Score -3

Tax? Quantities are different, but eagerness to avoid tax seems similar to Google. Principles matter. So same score: -8

Assorted messaging qualifies as additional to the pure social networking side I think so I’ll generously give them an extra bit for that: Score +2

They occasionally do good things with it like Google though. They also are developing a high altitude internet, and are playing with space exploration. Tiny bit of AI stuff, but not much else has crossed my consciousness. I think it is far less than Google but still positive, so I’ll score: +3

I honestly can’t think of any other significant contributions from Facebook to make the balance more positive, and I tried. I think they want to make a positive contribution, but are too focused on income to tackle the social negatives properly.

Total Facebook contribution to humanity: -14.

Oh dear! Must do better.

Conclusion: We’d be a lot worse off without Google. Even with their faults, they still make a great contribution to humankind. Maybe not quite a ‘do no evil’ rating, but certainly they qualify for ‘do net good’. On the other hand, sadly, I have to say that my analysis suggests we’d be a lot better off without Facebook. As much better off without them as we benefit by having Google.

If I have left something major out, good or bad, for either company please feel free to add your comments. I have deliberately left out their backing of their own political leanings and biases because whether you think they are good or bad depends where you are coming from. They’d only score about +/-3 anyway, which isn’t a game changer.

 

 

Chat-bots will help reduce loneliness, a bit

Amazon is really pushing its Echo and Dot devices at the moment and some other companies also use Alexa in their own devices. They are starting to gain avatar front ends too. Microsoft has their Cortana transforming into Zo, Apple has Siri’s future under wraps for now. Maybe we’ll see Siri in a Sari soon, who knows. Thanks to rapidly developing AI, chatbots and other bots have also made big strides in recent years, so it’s obvious that the two can easily be combined. The new voice control interfaces could become chatbots to offer a degree of companionship. Obviously that isn’t as good as chatting to real people, but many, very many people don’t have that choice. Loneliness is one of the biggest problems of our time. Sometimes people talk to themselves or to their pet cat, and chatting to a bot would at least get a real response some of the time. It goes further than simple interaction though.

I’m not trying to understate the magnitude of the loneliness problem, and it can’t solve it completely of course, but I think it will be a benefit to at least some lonely people in a few ways. Simply having someone to chat to will already be of some help. People will form emotional relationships with bots that they talk to a lot, especially once they have a visual front end such as an avatar. It will help some to develop and practice social skills if that is their problem, and for many others who feel left out of local activity, it might offer them real-time advice on what is on locally in the next few days that might appeal to them, based on their conversations. Talking through problems with a bot can also help almost as much as doing so with a human. In ancient times when I was a programmer, I’d often solve a bug by trying to explain how my program worked, and in doing so i would see the bug myself. Explaining it to a teddy bear would have been just as effective, the chat was just a vehicle for checking through the logic from a new angle. The same might apply to interactive conversation with a bot. Sometimes lonely people can talk too much about problems when they finally meet people, and that can act as a deterrent to future encounters, so that barrier would also be reduced. All in all, having a bot might make lonely people more able to get and sustain good quality social interactions with real people, and make friends.

Another benefit that has nothing to do with loneliness is that giving a computer voice instructions forces people to think clearly and phrase their requests correctly, just like writing a short computer program. In a society where so many people don’t seem to think very clearly or even if they can, often can’t express what they want clearly, this will give some much needed training.

Chatbots could also offer challenges to people’s thinking, even to help counter extremism. If people make comments that go against acceptable social attitudes or against known facts, a bot could present the alternative viewpoint, probably more patiently than another human who finds such viewpoints frustrating. I’d hate to see this as a means to police political correctness, though it might well be used in such a way by some providers, but it could improve people’s lack of understanding of even the most basic science, technology, culture or even politics, so has educational value. Even if it doesn’t convert people, it might at least help them to understand their own views more clearly and be better practiced at communicating their arguments.

Chat bots could make a significant contribution to society. They are just machines, but those machines are tools for other people and society as a whole to help more effectively.

 

Future Augmented Reality

AR has been hot on the list of future IT tech for 25 years. It has been used for various things since smartphones and tablets appeared but really hit the big time with the recent Pokemon craze.

To get an idea of the full potential of augmented reality, recognize that the web and all its impacts on modern life came from the convergence of two medium sized industries – telecoms and computing. Augmented reality will involve the convergence of everything in the real world with everything in the virtual world, including games, media, the web, art, data, visualization, architecture, fashion and even imagination. That convergence will be enabled by ubiquitous mobile broadband, cloud, blockchain payments, IoT, positioning and sensor tech, image recognition, fast graphics chips, display and visor technology and voice and gesture recognition plus many other technologies.

Just as you can put a Pokemon on a lawn, so you could watch aliens flying around in spaceships or cartoon characters or your favorite celebs walking along the street among the other pedestrians. You could just as easily overlay alternative faces onto the strangers passing by.

People will often want to display an avatar to people looking at them, and that could be different for every viewer. That desire competes with the desire of the viewer to decide how to see other people, so there will be some battles over who controls what is seen. Feminists will certainly want to protect women from the obvious objectification that would follow if a woman can’t control how she is seen. In some cases, such objectification and abuse could even reach into hate crime territory, with racist, sexist or homophobic virtual overlays. All this demands control, but it is far from obvious where that control would come from.

As for buildings, they too can have a virtual appearance. Virtual architecture will show off architect visualization skills, but will also be hijacked by the marketing departments of the building residents. In fact, many stakeholders will want to control what you see when you look at a building. The architects, occupants, city authorities, government, mapping agencies, advertisers, software producers and games designers will all try to push appearances at the viewer, but the viewer might want instead to choose to impose one from their own offerings, created in real time by AI or from large existing libraries of online imagery, games or media. No two people walking together on a street would see the same thing.

Interior decor is even more attractive as an AR application. Someone living in a horrible tiny flat could enhance it using AR to give the feeling of far more space and far prettier decor and even local environment. Virtual windows onto Caribbean beaches may be more attractive than looking at mouldy walls and the office block wall that are physically there. Reality is often expensive but images can be free.

Even fashion offers a platform for AR enhancement. An outfit might look great on a celebrity but real life shapes might not measure up. Makeovers take time and money too. In augmented reality, every garment can look as it should, and that makeup can too. The hardest choice will be to choose a large number of virtual outfits and makeups to go with the smaller range of actual physical appearances available from that wardrobe.

Gaming is in pole position, because 3D world design, imagination, visualization and real time rendering technology are all games technology, so perhaps the biggest surprise in the Pokemon success is that it was the first to really grab attention. People could by now be virtually shooting aliens or zombies hoarding up escalators as they wait for their partners. They are a little late, but such widespread use of personal or social gaming on city streets and in malls will come soon.

AR Visors are on their way too, and though the first offerings will be too expensive to achieve widespread adoption, cheaper ones will quickly follow. The internet of things and sensor technology will create abundant ground-up data to make a strong platform. As visors fall in price, so too will the size and power requirements of the processing needed, though much can be cloud-based.

It is a fairly safe bet that marketers will try very hard to force images at us and if they can’t do that via blatant in-your-face advertising, then product placement will become a very fine art. We should expect strong alliances between the big marketing and advertising companies and top games creators.

As AI simultaneously develops, people will be able to generate a lot of their own overlays, explaining to AI what they’d like and having it produced for them in real time. That would undermine marketing use of AR so again there will be some battles for control. Just as we have already seen owners of landmarks try to trademark the image of their buildings to prevent people including them in photographs, so similar battles will fill the courts over AR. What is to stop someone superimposing the image of a nicer building on their own? Should they need to pay a license to do so? What about overlaying celebrity faces on strangers? What about adding multimedia overlays from the web to make dull and ordinary products do exciting things when you use them? A cocktail served in a bar could have a miniature Sydney fireworks display going on over it. That might make it more exciting, but should the media creator be paid and how should that be policed? We’ll need some sort of AR YouTube at the very least with added geolocation.

The whole arts and media industry will see city streets as galleries and stages on which to show off and sell their creations.

Public services will make more mundane use of AR. Simple everyday context-dependent signage is one application, but overlays would be valuable in emergencies too. If police or fire services could superimpose warning on everyone’s visors nearby, that may help save lives in emergencies. Health services will use AR to assist ordinary people to care for a patient until an ambulance arrives

Shopping provide more uses and more battles. AR will show you what a competing shop has on offer right beside the one in front of you. That will make it easy to digitally trespass on a competitor’s shop floor. People can already do that on their smartphone, but AR will put the full image large as life right in front of your eyes to make it very easy to compare two things. Shops won’t want to block comms completely because that would prevent people wanting to enter their shop at all, so they will either have to compete harder or find more elaborate ways of preventing people making direct visual comparisons in-store. Perhaps digital trespassing might become a legal issue.

There will inevitably be a lot of social media use of AR too. If people get together to demonstrate, it will be easier to coordinate them. If police insist they disperse, they could still congregate virtually. Dispersed flash mobs could be coordinated as much as ones in the same location. That makes AR a useful tool for grass-roots democracy, especially demonstrations and direct action, but it also provides a platform for negative uses such as terrorism. Social entrepreneurs will produce vast numbers of custom overlays for millions of different purposes and contexts. Today we have tens of millions of websites and apps. Tomorrow we will have even more AR overlays.

These are just a few of the near term uses of augmented reality and a few hints as issues arising. It will change every aspect of our lives in due course, just as the web has, but more so.

 

Cellular blockchain, cellular bitcoin

Bitcoin has been around a while and the blockchain foundations on which it is built are extending organically into other areas.

Blockchain is a strongly encrypted distributed database, a ledger that records every transaction. That’s all fine, it works OK, and it doesn’t need fixed.

However, for some applications or new cryptocurrencies, there may be some benefit in making a cellular blockchain to limit database size, protect against network outage, and harden defenses against any local decryption. These may become important as cyber-terrorism increases and as quantum computing develops. They would also be more suited to micro-transactions and micro-currencies.

If you’ve made it this far, you almost certainly don’t need any further explanation.
