Spiders in Space

A while back I read an interesting article about how small spiders get into the air to disperse, even when there is no wind:

Spiders go ballooning on electric fields: https://phys.org/news/2018-07-spiders-ballooning-electric-fields.html

If you don’t want to read it, the key point is that they use the electric fields in the air to provide enough force to drag them into the air. It gave me an idea. Why not use that same technique to get into space?

There is electric air potential right up to the very top of the atmosphere, but electric fields permeate space too. It only provides a weak force, enough to lift a 25mg spider using the electrostatic force on a few threads from its spinnerets.

25mg isn’t very heavy, but then the threads are only designed to lift the spider. Longer threads could generate higher forces, and lots of longer threads working together could generate significant forces. I’m not thinking of using this to launch space ships though. All I want for this purpose is to lift a few grams and that sounds feasible.

If we can arrange for a synthetic ‘cyber-spider’ to eject long graphene threads in the right directions, and to wind them back in when appropriate, our cyber-spider could harness these electric forces to crawl slowly into space, and then maintain altitude. It won’t need to stay in exactly the same place, but could simply use the changing fields and forces to stay within a reasonably small region. It won’t have used any fuel or rockets to get there or stay there, but now it is in space, even if it isn’t very high, it could be quite useful, even though it is only a few grams in weight.

Suppose our invisibly small cyber-spider sits near the orbit of a particular piece of space junk. The space junk moves fast, and may well be much larger than our spider in terms of mass, but if a few threads of graphene silk were to be in its path, our spider could effectively ensnare it, cause an immediate drop of speed due to Newtonian sharing of momentum (the spider has to be accelerated to the same speed as the junk, from stationary so even though it is much lighter, that would still cause a significant drop in junk speed)) and then use its threads as a mechanism for electromagnetic drag, causing it to slowly lose more speed and fall out of orbit. That might compete well as a cheap mechanism for cleaning up space junk.

Some organic spiders can kill a man with a single bite, and space spiders could do much the same, albeit via a somewhat different process. Instead of junk, our spider could meander into collision course with an astronaut doing a space walk. A few grams isn’t much, but a stationary cyber-spider placed in the way of a rapidly moving human would have much the same effect as a very high speed rifle shot.

The astronaut could easily be a satellite. Its location could be picked to impact on a particular part of the satellite to do most damage, or to cause many fragments, and if enough fragments are created – well, we’ve all watched Gravity and know what high speed fragments of destroyed satellites can do.

The spider doesn’t even need to get itself into a precise position. If it has many threads going off in various directions, it can quickly withdraw some of them to create a Newtonian reaction to move its center of mass fast into a path. It might sit many meters away from the desired impact position, waiting until the last second to jump in front of the astronaut/satellite/space junk.

What concerns me with this is that the weapon potential lends itself to low budget garden shed outfits such as lone terrorists. It wouldn’t need rockets, or massively expensive equipment. It doesn’t need rapid deployment, since being invisible, could migrate to its required location over days, weeks or months. A large number of them could be invisibly deployed from a back garden ready for use at any time, waiting for the command before simultaneously wiping out hundreds of satellites. It only needs a very small amount of IT attached to some sort of filament spinneret. A few years ago I worked out how to spin graphene filaments at 100m/s:

Spiderman-style silk thrower

If I can do it, others can too, and there are probably many ways to do this other than mine.

If you aren’t SpiderMan, and can accept lower specs, you could make a basic graphene silk thrower and associated IT that fits in the few grams weight budget.

There are many ways to cause havoc in space. Spiders have been sci-fi horror material for decades. Soon space spiders could be quite real.

 

 

Instant buildings: Kinetic architecture

Revisiting an idea I raised in a blog in July last year. Even I think it was badly written so it’s worth a second shot.

Construction techniques are diverse and will get diverser. Just as we’re getting used to seeing robotic bricklaying and 3D printed walls, another technique is coming over the horizon that will build so fast I call it kinetic architecture. The structure will be built so quickly it can build a bridge from one side just by building upwards at an angle, and the structure will span the gap and meet the ground at the other side before gravity has a chance to collapse it.

The key to such architecture is electromagnetic propulsion, the same as on the Japanese bullet trains or the Hyperloop, using magnetic forces caused by electric currents to propel the next piece along the existing structure to the front end where it acts as part of the path for the next. Adding pieces quickly enough leads to structures that can follow elegant paths, as if the structure is a permanent trace of the path an object would have followed if it were catapulted into the air and falling due to gravity. It could be used for buildings, bridges, or simply art.

It will become possible thanks to new materials such as graphene and other carbon composites using nanotubes. Graphene combines extreme strength, hence lightness for a particular strength requirement, with extreme conductivity, allowing it to carry very high electric currents, and therefore able to generate high magnetic forces. It is a perfect material for kinetic architecture. Pieces would have graphene electromagnet circuitry printed on their surface. Suitable circuit design would mean that every extra piece falling into place becomes an extension to the magnetic railway transporting the next piece. Just as railroads may be laid out just in front of the train using pieces carried by the train, so pieces shot into the air provide a self-building path for other pieces to follow. A building skeleton could be erected in seconds. I mentioned in my original blog (about carbethium) that this could be used to create the sort of light bridges we see in Halo. A kinetic architecture skeleton would be shot across the divide and the filler pieces in between quickly transported into place along the skeleton and assembled.

See https://timeguide.wordpress.com/2016/07/25/carbethium-a-better-than-scifi-material/. The electronic circuitry potential for graphene also allows for generating plasma or simply powering LEDs to give a nice glow just like the light bridges too.

Apart from clever circuit design, kinetic architecture also requires pieces that can interlock. The kinetic energy of the new piece arriving at the front edge would ideally be sufficient to rotate it into place, interlocking with previous front edge. 3d interlocking is tricky but additional circuitry can provide additional magnetic forces to rotate and translate pieces if kinetic energy alone isn’t enough. The key is that once interlocked, the top surface has to form a smooth continuous line with the previous one, so that pieces can move along smoothly. Hooks can catch an upcoming piece to make it rotate, with the hooks merging nicely with part of the new piece as it falls into place, making those hooks part of a now smooth surface and a new hook at the new front end. You’ll have to imagine it yourself, I can’t draw it. Obviously, pieces would need precision engineering because they’d need to fit precisely to give the required strength and fit.

Ideally, with sufficiently well-designed pieces, it should be possible to dismantle the structure by reversing the build process, unlocking each end piece in turn and transporting it back to base along the structure until no structure remains.

I can imagine such techniques being used at first for artistic creations, sculptures using beautiful parabolic arcs. But they could also be used for rapid assembly for emergency buildings, instant evacuation routes for tall buildings, or to make temporary bridges after an earthquake destroyed a permanent one. When a replacement has been made, the temporary one could be rolled back up and used elsewhere. Maybe it could become routine for making temporary structures that are needed quickly such as for pop concerts and festivals. One day it could become an everyday building technique. 

Mega-buildings could become cultural bubbles

My regular readers, both of them in fact, will know I am often concerned about the dangerous growth of social media bubbles. By mid-century, thanks to upcoming materials, some cities will have a few buildings over 1km tall, possibly 10km (and a spaceport or two up to 30km high). These would be major buildings, and could create a similar problem.

A 1km building could have 200 floors, and with 100m square floors, 200 hectares of space.  Assuming half is residential space and the other half is shops, offices or services, that equates to 20,000 luxury apartments (90 sq m each) or 40,000 basic flats. That means each such building could be equivalent to a small town, with maybe 50,000 inhabitants. A 10km high mega-building, with a larger 250m side, would have 60 times more space, housing up to 300,000 people and all they need day-to-day, essentially a city.

Construction could be interesting. My thoughts are that a 10km building could be extruded from the ground using high pressure 3D printing, rather than assembled with cranes. Each floor could be fully fitted out while it is still near ground level, its apartments sold and populated, even as the building grows upward. That keeps construction costs and cash flow manageable.

My concern is that although we will have the technology to build such buildings in the 2040s, I’m not aware of much discussion about how cultures would evolve in such places, at least not outside of sci-fi (like Judge Dredd or Blade Runner). I rather hope we wouldn’t just build them first and try to solve social problems later. We really ought to have some sort of plans to make them work.

In a 100m side building, entire floors or groups of floors would likely be allocated to particular functions – residential, shopping, restaurants, businesses etc. Grouping functions sensibly reduces the total travel needed. In larger buildings, it is easier to have local shops mixed with apartments for everyday essentials, with larger malls elsewhere.

People could live almost entirely in the building, rarely needing to leave, and many might well do just that, essentially becoming institutionalized. I think these buildings will feel very different from small towns. In small towns, people still travel a lot to other places, and a feeling of geographic isolation doesn’t emerge. In a huge tower block of similar population and facilities, I don’t think people would leave as often, and many will stay inside. All they need is close by and might soon feel safe and familiar, while the external world might seem more distant, scarier. Institutionalization might not take long, a month or two of becoming used to the convenience of staying nearby while watching news of horrors going on elsewhere. Once people stop the habit of leaving the building, it could become easier to find reasons not to leave it in future.

Power structures would soon evolve – local politics would happen, criminal gangs would emerge, people would soon learn of good and bad zones. It’s possible that people might become tribal, their building and their tribe competing for external resources and funding with tribes in other mega-buildings, and their might be conflict. Knowing they are physically detached, the same bravery to attack total strangers just because they hold different views might emerge that we see on social media today. There might be cyber-wars, drone wars, IoT wars between buildings.

I’m not claiming to be a social anthropologist. I have no real idea how these buildings will work and perhaps my fears are unjustified. But even I can see some potential problems just based on what we see today, magnified for the same reasons problems get magnified on social media. Feelings of safety and anonymity can lead to some very nasty tribal behaviors. Managing diversity of opinion among people moving in would be a significant challenge, maintaining it might be near impossible. With the sort of rapid polarization we’ve already seen today thanks to social media bubbles, physically contained communities would surely see those same forces magnified everyday.

Building a 10km mega-building will become feasible in the 2040s, and increased urban populations will make them an attractive option for planners. Managing them and making them work socially might be a much bigger challenge.

 

 

Carbethium, a better-than-scifi material

How to build one of these for real:

Light_bridge

Halo light bridge, from halo.wikia.com

Or indeed one of these:

From halo.wikia.com

From halo.wikia.com

I recently tweeted that I had an idea how to make the glowy bridges and shields we’ve seen routinely in sci-fi games from Half Life to Destiny, the bridges that seem to appear in a second or two from nothing across a divide, yet are strong enough to drive tanks over, and able to vanish as quickly and completely when they are switched off. I woke today realizing that with a bit of work, that it could be the basis of a general purpose material to make the tanks too, and buildings and construction platforms, bridges, roads and driverless pod systems, personal shields and city defense domes, force fields, drones, planes and gliders, space elevator bases, clothes, sports tracks, robotics, and of course assorted weapons and weapon systems. The material would only appear as needed and could be fully programmable. It could even be used to render buildings from VR to real life in seconds, enabling at least some holodeck functionality. All of this is feasible by 2050.

Since it would be as ethereal as those Halo structures, I first wanted to call the material ethereum, but that name was already taken (for a 2014 block-chain programming platform, which I note could be used to build the smart ANTS network management system that Chris Winter and I developed in BT in 1993), and this new material would be a programmable construction platform so the names would conflict, and etherium is too close. Ethium might work, but it would be based on graphene and carbon nanotubes, and I am quite into carbon so I chose carbethium.

Ages ago I blogged about plasma as a 21st Century building material. I’m still not certain this is feasible, but it may be, and it doesn’t matter for the purposes of this blog anyway.

https://timeguide.wordpress.com/2013/11/01/will-plasma-be-the-new-glass/

Around then I also blogged how to make free-floating battle drones and more recently how to make a Star Wars light-saber.

https://timeguide.wordpress.com/2013/06/23/free-floating-ai-battle-drone-orbs-or-making-glyph-from-mass-effect/

https://timeguide.wordpress.com/2015/11/25/how-to-make-a-star-wars-light-saber/

Carbethium would use some of the same principles but would add the enormous strength and high conductivity of graphene to provide the physical properties to make a proper construction material. The programmable matter bits and the instant build would use a combination of 3D interlocking plates, linear induction,  and magnetic wells. A plane such as a light bridge or a light shield would extend from a node in caterpillar track form with plates added as needed until the structure is complete. By reversing the build process, it could withdraw into the node. Bridges that only exist when they are needed would be good fun and we could have them by 2050 as well as the light shields and the light swords, and light tanks.

The last bit worries me. The ethics of carbethium are the typical mixture of enormous potential good and huge potential for abuse to bring death and destruction that we’re learning to expect of the future.

If we can make free-floating battle drones, tanks, robots, planes and rail-gun plasma weapons all appear within seconds, if we can build military bases and erect shield domes around them within seconds, then warfare moves into a new realm. Those countries that develop this stuff first will have a huge advantage, with the ability to send autonomous robotic armies to defeat enemies with little or no risk to their own people. If developed by a James Bond super-villain on a hidden island, it would even be the sort of thing that would enable a serious bid to take over the world.

But in the words of Professor Emmett Brown, “well, I figured, what the hell?”. 2050 values are not 2016 values. Our value set is already on a random walk, disconnected from any anchor, its future direction indicated by a combination of current momentum and a chaos engine linking to random utterances of arbitrary celebrities on social media. 2050 morality on many issues will be the inverse of today’s, just as today’s is on many issues the inverse of the 1970s’. Whatever you do or however politically correct you might think you are today, you will be an outcast before you get old: https://timeguide.wordpress.com/2015/05/22/morality-inversion-you-will-be-an-outcast-before-youre-old/

We’re already fucked, carbethium just adds some style.

Graphene combines huge tensile strength with enormous electrical conductivity. A plate can be added to the edge of an existing plate and interlocked, I imagine in a hexagonal or triangular mesh. Plates can be designed in many diverse ways to interlock, so that rotating one engages with the next, and reversing the rotation unlocks them. Plates can be pushed to the forward edge by magnetic wells, using linear induction motors, using the graphene itself as the conductor to generate the magnetic field and the design of the structure of the graphene threads enabling the linear induction fields. That would likely require that the structure forms first out of graphene threads, then the gaps between filled by mesh, and plates added to that to make the structure finally solid. This would happen in thickness as well as width, to make a 3D structure, though a graphene bridge would only need to be dozens of atoms thick.

So a bridge made of graphene could start with a single thread, which could be shot across a gap at hundreds of meters per second. I explained how to make a Spiderman-style silk thrower to do just that in a previous blog:

https://timeguide.wordpress.com/2015/11/12/how-to-make-a-spiderman-style-graphene-silk-thrower-for-emergency-services/

The mesh and 3D build would all follow from that. In theory that could all happen in seconds, the supply of plates and the available power being the primary limiting factors.

Similarly, a shield or indeed any kind of plate could be made by extending carbon mesh out from the edge or center and infilling. We see that kind of technique used often in sci-fi to generate armor, from lost in Space to Iron Man.

The key components in carbetheum are 3D interlocking plate design and magnetic field design for the linear induction motors. Interlocking via rotation is fairly easy in 2D, any spiral will work, and the 3rd dimension is open to any building block manufacturer. 3D interlocking structures are very diverse and often innovative, and some would be more suited to particular applications than others. As for linear induction motors, a circuit is needed to produce the travelling magnetic well, but that circuit is made of the actual construction material. The front edge link between two wires creates a forward-facing magnetic field to propel the next plates and convey enough intertia to them to enable kinetic interlocks.

So it is feasible, and only needs some engineering. The main barrier is price and material quality. Graphene is still expensive to make, as are carbon nanotubes, so we won’t see bridges made of them just yet. The material quality so far is fine for small scale devices, but not yet for major civil engineering.

However, the field is developing extremely quickly because big companies and investors can clearly see the megabucks at the end of the rainbow. We will have almost certainly have large quantity production of high quality graphene for civil engineering by 2050.

This field will be fun. Anyone who plays computer games is already familiar with the idea. Light bridges and shields, or light swords would appear much as in games, but the material would likely  be graphene and nanotubes (or maybe the newfangled molybdenum equivalents). They would glow during construction with the plasma generated by the intense electric and magnetic fields, and the glow would be needed afterward to make these ultra-thin physical barriers clearly visible,but they might become highly transparent otherwise.

Assembling structures as they are needed and disassembling them just as easily will be very resource-friendly, though it is unlikely that carbon will be in short supply. We can just use some oil or coal to get more if needed, or process some CO2. The walls of a building could be grown from the ground up at hundreds of meters per second in theory, with floors growing almost as fast, though there should be little need to do so in practice, apart from pushing space vehicles up so high that they need little fuel to enter orbit. Nevertheless, growing a  building and then even growing the internal structures and even furniture is feasible, all using glowy carbetheum. Electronic soft fabrics, cushions and hard surfaces and support structures are all possible by combining carbon nanotubes and graphene and using the reconfigurable matter properties carbethium convents. So are visual interfaces, electronic windows, electronic wallpaper, electronic carpet, computers, storage, heating, lighting, energy storage and even solar power panels. So is all the comms and IoT and all the smart embdedded control systems you could ever want. So you’d use a computer with VR interface to design whatever kind of building and interior furniture decor you want, and then when you hit the big red button, it would appear in front of your eyes from the carbethium blocks you had delivered. You could also build robots using the same self-assembly approach.

If these structures can assemble fast enough, and I think they could, then a new form of kinetic architecture would appear. This would use the momentum of the construction material to drive the front edges of the surfaces, kinetic assembly allowing otherwise impossible and elaborate arches to be made.

A city transport infrastructure could be built entirely out of carbethium. The linear induction mats could grow along a road, connecting quickly to make a whole city grid. Circuit design allows the infrastructure to steer driverless pods wherever they need to go, and they could also be assembled as required using carbethium. No parking or storage is needed, as the pod would just melt away onto the surface when it isn’t needed.

I could go to town on military and terrorist applications, but more interesting is the use of the defense domes. When I was a kid, I imagined having a house with a defense dome over it. Lots of sci-fi has them now too. Domes have a strong appeal, even though they could also be used as prisons of course. A supply of carbetheum on the city edges could be used to grow a strong dome in minutes or even seconds, and there is no practical limit to how strong it could be. Even if lasers were used to penetrate it, the holes could fill in in real time, replacing material as fast as it is evaporated away.

Anyway, lots of fun. Today’s civil engineering projects like HS2 look more and more primitive by the day, as we finally start to see the true potential of genuinely 21st century construction materials. 2050 is not too early to expect widespread use of carbetheum. It won’t be called that – whoever commercializes it first will name it, or Google or MIT will claim to have just invented it in a decade or so, so my own name for it will be lost to personal history. But remember, you saw it here first.

Diabetes: Electronically controlled drug delivery via smart membrane

This is an invention I made in 2001 as part of my active skin suite to help diabetics. I’ve just been told I am another of the zillions of diabetics in the world so was reminded of it.

This wasn’t feasible in 2001 but it will be very soon, and could be an ideal way of monitoring blood glucose and insulin levels, checking with clinic AI for the correct does, and then opening the membrane pores just enough and long enough to allow the right dose of insulin to pass through. Obviously pore and drug particle design have to be coordinated, but this should be totally feasible. Here’s some pics:

The future of nylon: ladder-free hosiery

Last week I outlined the design for a 3D printer that can print and project graphene filaments at 100m/s. That was designed to be worn on the wrist like Spiderman’s, but an industrial version could print faster. When I checked a few of the figures, I discovered that the spinnerets for making nylon stockings run at around the same speed. That means that graphene stockings could be made at around the same speed. My print head produced 140 denier graphene yarn but it made that from many finer filaments so basically any yarn thickness from a dozen carbon atoms right up to 140 denier would be feasible.

The huge difference is that a 140 denier graphene thread is strong enough to support a man at 2g acceleration. 10 denier stockings are made from yarn that breaks quite easily, but unless I’ve gone badly wrong on the back of my envelope, 10 denier graphene would have roughly 10kg (22lb)breaking strain. That’s 150 times stronger than nylon yarn of the same thickness.

If so, then that would mean that a graphene stocking would have incredible strength. A pair of 10 denier graphene stockings or tights (pantyhose) might last for years without laddering. That might not be good news for the nylon stocking industry, but I feel confident they would adapt easily to such potential.

Alternatively, much finer yarns could be made that would still have reasonable ladder resistance, so that would also affect the visual appearance and texture. They could be made so fine that the fibers are invisible even up close. People might not always want that, but the key message is that wear-resistant, ladder free hosiery could be made that has any gauge from 0.1 denier to 140 denier.

There is also a bonus that graphene is a superb conductor. That means that graphene fibers could be woven into nylon hosiery to add circuits. Those circuits might be to harvest radio energy, act as an aerial, power LEDS in the hosiery or change its colors or patterns. So even if it isn’t used for the whole garment, it might still have important uses in the garment as an addition to the weave.

There is yet another bonus. Graphene circuits could allow electrical supply to shape changing polymers that act rather like muscles, contracting when a voltage is applied across them, so that a future pair of tights could shape a leg far better, with tensions and pressures electronically adjusted over the leg to create the perfect shape. Graphene can make electronic muscles directly too, but in a more complex mechanism (e.g. using magnetic field generation and interaction, or capacitors and electrical attraction/repulsion).

How to make a Spiderman-style graphene silk thrower for emergency services

I quite like Spiderman movies, and having the ability to fire a web at a distant object or villain has its appeal. Since he fires web from his forearm, it must be lightweight to withstand the recoil, and to fire enough to hold his weight while he swings, it would need to have extremely strong fibers. It is therefore pretty obvious that the material of choice when we build such a thing will be graphene, which is even stronger than spider silk (though I suppose a chemical ejection device making spider silk might work too). A thin graphene thread is sufficient to hold him as he swings so it could fit inside a manageable capsule.

So how to eject it?

One way I suggested for making graphene threads is to 3D print the graphene, using print nozzles made of carbon nanotubes and using a very high-speed modulation to spread the atoms at precise spacing so they emerge in the right physical patterns and attach appropriate positive or negative charge to each atom as they emerge from the nozzles so that they are thrown together to make them bond into graphene. This illustration tries to show the idea looking at the nozzles end on, but shows only a part of the array:printing graphene filamentsIt doesn’t show properly that the nozzles are at angles to each other and the atoms are ejected in precise phased patterns, but they need to be, since the atoms are too far apart to form graphene otherwise so they need to eject at the right speed in the right directions with the right charges at the right times and if all that is done correctly then a graphene filament would result. The nozzle arrangements, geometry and carbon atom sizes dictate that only narrow filaments of graphene can be produced by each nozzle, but as the threads from many nozzles are intertwined as they emerge from the spinneret, so a graphene thread would be produced made from many filaments. Nevertheless, it is possible to arrange carbon nanotubes in such a way and at the right angle, so provided we can get the high-speed modulation and spacing right, it ought to be feasible. Not easy, but possible. Then again, Spiderman isn’t real yet either.

The ejection device would therefore be a specially fabricated 3D print head maybe a square centimeter in area, backed by a capsule containing finely powdered graphite that could be vaporized to make the carbon atom stream through the nozzles. Some nice lasers might be good there, and some cool looking electronic add-ons to do the phasing and charging. You could make this into one heck of a cool gun.

How thick a thread do we need?

Assuming a 70kg (154lb) man and 2g acceleration during the swing, we need at least 150kg breaking strain to have a small safety margin, bearing in mind that if it breaks, you can fire a new thread. Steel can achieve that with 1.5mm thick wire, but graphene’s tensile strength is 300 times better than steel so 0.06mm is thick enough. 60 microns, or to put it another way, roughly 140 denier, although that is a very quick guess. That means roughly the same sort of graphene thread thickness is needed to support our Spiderman as the nylon used to make your backpack. It also means you could eject well over 10km of thread from a 200g capsule, plenty. Happy to revise my numbers if you have better ones. Google can be a pain!

How fast could the thread be ejected?

Let’s face it. If it can only manage 5cm/s, it is as much use as a chocolate flamethrower. Each bond in graphene is 1.4 angstroms long, so a graphene hexagon is about 0.2nm wide. We would want our graphene filament to eject at around 100m/s, about the speed of a crossbow bolt. 100m/s = 5 x 10^11 carbon atoms ejected per second from each nozzle, in staggered phasing. So, half a terahertz. Easy! That’s well within everyday electronics domains. Phew! If we can do better, we can shoot even faster.

We could therefore soon have a graphene filament ejection device that behaves much like Spiderman’s silk throwers. It needs some better engineers than me to build it, but there are plenty of them around.

Having such a device would be fun for sports, allowing climbers to climb vertical rock faces and overhangs quickly, or to make daring leaps and hope the device works to save them from certain death. It would also have military and police uses. It might even have uses in road accident prevention, yanking pedestrians away from danger or tethering cars instantly to slow them extra quickly. In fact, all the emergency services would have uses for such devices and it could reduce accidents and deaths. I feel confident that Spiderman would think of many more exciting uses too.

Producing graphene silk at 100m/s might also be pretty useful in just about every other manufacturing industry. With ultra-fine yarns with high strength produced at those speeds, it could revolutionize the fashion industry too.

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.

Stimulative technology

You are sick of reading about disruptive technology, well, I am anyway. When a technology changes many areas of life and business dramatically it is often labelled disruptive technology. Disruption was the business strategy buzzword of the last decade. Great news though: the primarily disruptive phase of IT is rapidly being replaced by a more stimulative phase, where it still changes things but in a more creative way. Disruption hasn’t stopped, it’s just not going to be the headline effect. Stimulation will replace it. It isn’t just IT that is changing either, but materials and biotech too.

Stimulative technology creates new areas of business, new industries, new areas of lifestyle. It isn’t new per se. The invention of the wheel is an excellent example. It destroyed a cave industry based on log rolling, and doubtless a few cavemen had to retrain from their carrying or log-rolling careers.

I won’t waffle on for ages here, I don’t need to. The internet of things, digital jewelry, active skin, AI, neural chips, storage and processing that is physically tiny but with huge capacity, dirt cheap displays, lighting, local 3D mapping and location, 3D printing, far-reach inductive powering, virtual and augmented reality, smart drugs and delivery systems, drones, new super-materials such as graphene and molybdenene, spray-on solar … The list carries on and on. These are all developing very, very quickly now, and are all capable of stimulating entire new industries and revolutionizing lifestyle and the way we do business. They will certainly disrupt, but they will stimulate even more. Some jobs will be wiped out, but more will be created. Pretty much everything will be affected hugely, but mostly beneficially and creatively. The economy will grow faster, there will be many beneficial effects across the board, including the arts and social development as well as manufacturing industry, other commerce and politics. Overall, we will live better lives as a result.

So, you read it here first. Stimulative technology is the next disruptive technology.

 

The future of creativity

Another future of… blog.

I can play simple tunes on a guitar or keyboard. I compose music, mostly just bashing out some random sequences till a decent one happens. Although I can’t offer any Mozart-level creations just yet, doing that makes me happy. Electronic keyboards raise an interesting point for creativity. All I am actually doing is pressing keys, I don’t make sounds in the same way as when I pick at guitar strings. A few chips monitor the keys, noting which ones I hit and how fast, then producing and sending appropriate signals to the speakers.

The point is that I still think of it as my music, even though all I am doing is telling a microprocessor what to do on my behalf. One day, I will be able to hum a few notes or tap a rhythm with my fingers to give the computer some idea of a theme, and it will produce beautiful works based on my idea. It will still be my music, even when 99.9% of the ‘creativity’ is done by an AI. We will still think of the machines and software just as tools, and we will still think of the music as ours.

The other arts will be similarly affected. Computers will help us build on the merest hint of human creativity, enhancing our work and enabling us to do much greater things than we could achieve by our raw ability alone. I can’t paint or draw for toffee, but I do have imagination. One day I will be able to produce good paintings, design and make my own furniture, design and make my own clothes. I could start with a few downloads in the right ballpark. The computer will help me to build on those and produce new ones along divergent lines. I will be able to guide it with verbal instructions. ‘A few more trees on the hill, and a cedar in the foreground just here, a bit bigger, and move it to the left a bit’. Why buy a mass produced design when you can have a completely personal design?

These advances are unlikely to make a big dent in conventional art sales. Professional artists will always retain an edge, maybe even by producing the best seeds for computer creativity. Instead, computer assisted and computer enhanced art will make our lives more artistically enriched, and ourselves more fulfilled as a result. We will be able to express our own personalities more effectively in our everyday environment, instead of just decorating it with a few expressions of someone else’s.

However, one factor that seems to be overrated is originality. Anyone can immediately come up with many original ideas in seconds. Stick a safety pin in an orange and tie a red string through the loop. There, can I have my Turner prize now? There is an infinitely large field to pick from and only a small number have ever been realized, so coming up with something from the infinite set that still haven’t been thought of is easy and therefore of little intrinsic value. Ideas are ten a penny. It is only when it is combined with judgement or skill in making it real that it becomes valuable. Here again, computers will be able to assist. Analyzing a great many existing pictures or works or art should give some clues as to what most people like and dislike. IBM’s new neural chip is the sort of development that will accelerate this trend enormously. Machines will learn how to decide whether a picture is likely to be attractive to people or not. It should be possible for a computer to automatically create new pictures in a particular style or taste by either recombining appropriate ideas, or just randomly mixing any ideas together and then filtering the new pictures according to ‘taste’.

Augmented reality and other branches of cyberspace offer greater flexibility. Virtual objects and environments do not have to conform to laws of physics, so more elaborate and artistic structures are possible. Adding in 3D printing extends virtual graphics into the physical domain, but physics will only apply to the physical bits, and with future display technology, you might not easily be able to see where the physical stops and the virtual begins.

So, with machine assistance, human creativity will no longer be as limited by personal skill and talent. Anyone with a spark of creativity will be able to achieve great works, thanks to machine assistance. So long as you aren’t competitive about it, (someone else will always be able to do it better than you) your world will feel nicer, more friendly and personal, you’ll feel more in control, empowered, and your quality of life will improve. Instead of just making do with what you can buy, you’ll be able to decide what your world looks, sounds, feels, tastes and smells like, and design personality into anything you want too.
