The Future of Nanobiotech Predicted 130

Quadraginta writes "Aharon Hauptman and Yair Sharan of the Interdisciplinary Center for Technology Analysis and Forecasting (ICTAF) at Tel Aviv University recently presented the results of a survey of 139 researchers on the future of nanobiotech. The presentation itself is only available as a PDF file, but there is a brief news announcement from the ICTAF. Interestingly, Hauptman and Sharan asked for -- and got -- specific predictions from the experts of the year in which various nanotech marvels will appear. For example, the experts say we can look forward to biosensors capable of detecting a single molecule by 2015, the direct construction of artificial human organs by 2020, and the use of nanomachines inside the body for diagnosis and therapy by 2025."

    Wait, that was a good analogy.
    • Artificial intelligence, i.e. thinking machines, are always about 10 years away. They have been for years.

      That's not quite true. AI used to be always 50 years away. Not that that means much, of course. I believe we still have no idea what it is we're actually looking for, and keep redefining it (people used to think that a computer playing chess would be AI).

      • I'd say the best chance we have to get true AI is to build quantum computers. Constant creation of wavestates and the spontaneus collapse due to gravity will generate a flurry of "thoughts" - and by learning the successful ones will eventuelly be "stored" using neural networks.

        That's one of the theories behind how the human brain works, and it's the "randomness" in it that I feel is sorely lacking from current static neural network thinking.

          I don't agree at all. Human brains work by neurons firing in specific patterns, in specific ways, in extremely huge numbers and with complicated interneuron connections. There is no quick fix to knowing how the brain works, since it's not a simple thing.

          That said, even if the brain relied on some quantum effect, I find the idea that just building something completely different that also relies on a quantum effect (a quantum computer) and just letting it run (doing what?) to be pretty bizarre.

          The main problem to solving "true AI" remains _defining true AI_. You can't solve a problem if nobody can say what the actual problem is.

          • Yup, we have to understand better how minds work. Or at least enough to make a copy of them.

            And then we also need the processor power equal to that of the brain too. It could well be argued that the Internet crossed that line quite some time ago. But the structure of the Internet is not even close to mind-like. Though there are possibilities...

            At any rate, what gets interesting is that we've just recently crossed that same line with "single" entities like the IBM BlueGene supercomputer cluster.

          • It would be ironic and amusing if it turned out that, after all, artificial intelligence wasn't nearly as difficult a problem to solve as folks like Scarbrac thought and that the only reason that it took us so long to solve was because we desperately wanted to hold onto the notion that intelligence was a hard thing to recreate.
            • I'm sure there are computing systems around today that hobbyists will load up with functioning AIs once they code up a working AI, the way people today write a HAL layer for Linux to bring it up on a wristwatch or a Coleco Adam or some such (has that been done? Vic 20?)
          • People are already trying to solve this problem. They're working to create Friendly AI, not through technology, but through definition of the human brain and our thought processes. Check out some of their work at: http://www.singinst.org/ [singinst.org]

            If they succeed, they hope to create a Singularity, a point at which we have no ability to predict what lay beyond, sheerly due to the intelligences involved.
          • I doubt we'll ever have real artificial intelligence anytime soon, if we're smart enough anyways. Mostly because to create a real AI, you need to give it a purpose or reason to survive... think about how life itself works in general. Survival instincts precipitate change. If we do indeed create real AI, it might turn into something out of the matrix. Just we won't be living in some silly dreamworld. We'll probably just cease to exist because we're horribly inefficient anyways.
            • You said it yourself. Survival *instinct*. Instincts are creature-specific, and environmentally defined. They don't define or require much intelligence. It is a trait of self-awareness. People have survival instincts because they know without certain things they will perish. A computer requires power, and software.

              Artificial intelligence already exists. It will become *actual* intelligence when it can program and reprogram itself.

            Well said. Most attempts to achieve true machine intelligence boil down to "we don't know how this works, but if we throw enough processing power/memory/neural net nodes at it, maybe it'll start to think". These brute force attempts are not particularly elegant, but in some cases they do teach us some things (much like particle accellerators do) to better define t

        As a "nano" researcher myself, I have started to almost think the tide is turning the other way. We have lots of momentum, but I no longer think we are accelerating.

        Of course, it all depends on your measure. If you just count number of journal pages printed, or number of scientists researching, things seem hunky-dory. However, if you multiply that by the value of that information, it shrinks substantially. Science has become exceptionally incremental, and we are advancing via zerg-style attack rather than leaps and bounds.

        At least from my position here on the inside, I feel that these estimates are quite optimistic.

          I'm also a "nano" researcher, and while I agree that alot of the recent papers havent been huge advances, the fact that characterization methods are very limited at this scale makes it important to learn techniques that work wonderfully as well as those that work minimally at best.

          I too work in nanotechnology. In fact, the company I work for just kicked out their first product, a carbon nanotubes based memory cell. I completely disagree with you. I think we are moving forward at a blistering pace that is just getting faster.

          I suggest holding onto your ass, as pharmaceutical companies are about to start blasting new useful products. You need to remember that what we see in a lot of industries is on a time lag. It takes a bare minimum of 10-15 years to create a drug from scratch and get it through the FDA. Think about that for a moment. The drugs being released today come from before the Internet was being widely used. The fruits of these efforts are already starting to become clear. My father for instance probably just tacked an extra 10-20 years onto his life with new cholesterol lowering drug. Things are only going to get better.

          Everything is shrinking at an accelerated rate. The amount of information that we have access to is expanding exponentially. As a culture, we are so used to change that we are utterly blind to it when it happens. 5 years ago I knew only one or two people with cell phones, and those people rarely used them. I recall having friends who swore they would never own one of those damn things.

          Just the other day I ran into the first person I have met in the past year under the age of 50 who doesn't own a cell phone. This guy came to a gathering of about a dozen people that I was throwing. We were crowded in my living room when someone asked what his cell phone number was so they could coordinate meeting up the next day. The guy said he didn't own a cell phone. That statement brought conversation in the room to a dead stop. The group then spent a few minutes trying to figure out how in the hell you coordinate meeting at a park if you can't use a cell phone. In this group, there were people that just 5 years ago swore they would never use a cell phone. Now, they have to struggle to remember how meet up with someone without using a cell phone.

          As a culture we are desensitized to change. We don't suffer from 'future shock' as some futurist thought we would. As new things come we roll with it very well. Show a guy from 1990 the year 2006, and he would be awed. True, we don't have floating cars or cool looking buildings. A city street today looks roughly like a city street from 15 years ago. What a person from 1990 WOULD notice right away is the fact that everyone owns a cell phone. They would be blown away by how trivial it is to get knowledge simply by using the Internet. The speed and power of our computers, or games, and our MP3 players would be unlike anything they could have imagined possible. They would recognize that socially technology is changing how we interact at a blistering rate.

          Things are accelerating very quickly. There might be a limit or a set of breaks out there somewhere, but it sure as hell isn't in sight right now. The best is without a doubt yet to come.

            I'm not sure that's a very good analogy to be honest. Cell phones are based on technologies which are decades old, well understood and have been incrementally advanced. It could be argued that it has taken half a century to realise the telecommunications systems which we have today.

Or are there wildly successful visionaries with high accuracy of whose publications we are now unaware? I'd love to see a discussion of futurists' predictions that HAVE been surprisingly accurate.

    It seems pointless to make specific predictions, such as Technology X in Year Y. Might it not be better to simply steer our unwieldy technology, as well as we can, in a generally sensible direction?

    • SciFi writers have been very good at predicting human advancement.

      I suspect this is because they research rather than speculate, and they believe in their predictions enough that they flesh them out by writing detailed descriptions of what life would be like after their predictions come true.
      • " SciFi writers have been very good at predicting human advancement.

        Agreed. However they do not seem at all good at predicting the when as well as the what. They have 'tech X' but not the 'year Y' part.

      • But aren't scientists often inspired by Science Fiction?
      • SciFi writers have been very good at predicting human advancement.

        It's because their loyal followers with super-huge brains have nothing better to do than try and create the tools of the future. Think about a little kid recreating a fight scene they saw on TV. They think it's cool and want to reenact so they can be cool.

    • Predictions are tools of perception. People use predictions to better understand phenomena and to create better goals and plans.
      Predictions are ideas so they affect people's thinking; they give us new ideas, new perspectives and insights.
      The gap between ideas and technology is continuously narrowing and that makes predictions about our technological future more and more like inventions.

      I would suggest reading Alvin Toffler's _Future_Shock_ (1970) and _The_Third_Wave_ (1980). Still the best two texts that I've ever read for understanding how technology is affecting how society changes. The overall view represented by these two books is fairly accurate. Naturally, he didn't get all the details right. Still, well worth a read.
      • But IIRC Toffler's Future Shock completely missed out on the forthcoming new means of communication (such as the Internet) and the radically different ways we interact nowadays. Been awhile since I reread, but it seemed like an extrapolation of 1960s life with the only difference being acceleration of industrial change.

        We need a new Future Shock for this new century, which can be snapshot periodically (for posterity) and updated regularly as technology allows.

    One thing that is rarely discussed about nano-technology is the possible harm it could do to living organisms. If someone is ingesting nano-technology unwittingly through the air, water, or food, it is possible it could do great harm. Also, since it is almost impossible to see and track, what happens when it creates unintended harm? Who is held responsible and how do you clean it up?

    That being said, I am for new technology and I am hoping nano-tech will be used in a responsible manner.
    • "since it is almost impossible to see and track,"

      One of the predictions is that we'll be able to detect single molecules in solution. That seems like pretty good tracking to me.

      • I think you misinterpret the prediction. 'They' will be able to detect single molecules (with expensive and limited systems in an appropriate test environment). You and I will not. Which is the worrisome part for some when nanotechnology is mentioned.

    Maybe the technological breakthroughs will occur in the predicted timelines, but if you tack on all the regulatory issues, one should really add an additional 25 years to the timelines. The great deal of uncertainty on how these nanoscale devices really affect health, as well as regulatory approval of such devices means just as much research to determine that nanobiotech is really ready for safe use. And let's face it - nanobiotech is basically a new term for molecular biology, and we continue to learn a great deal every day in that field, especially how hard it is to get things to work right at that level if we come up with it.

    That being said - some countries may see this tech before others. I'm betting Singapore comes up with this type of technology first. If the regs are such that its more open to widespread use in that country or others, then maybe the timelines will only be 10-15 years off.
  • Has anyone seen that Outer Limits episide where they have nano-technology and they use it on some guy to cure his cancer I think. As the episode goes on, the nanobots refused to let the man die through his many attempts at suicide, repairing stab wounds, burns etc. By the end of the episode, he had gills and and eyes on the back of his head.
    • there's a webcomic called Alien Dice [aliendice.com], where the space gladiators are given "nanites" that heal them of all wounds, even in cases of attempted suicide.

      This is a small world, indeed.

    I'm sure that it's just a matter of designing nanotechnology monkeys.

    While it's relatively easy to predict some technological developments (i.e., color TV when you already have black-and-white TV), most of the real innovations sneak up on us unexpectedly. Even Microsoft, the biggest computer technology company in the world, totally missed the importance of the Internet until it was already here.
    I predict that, while some of these things may happen, and may even happen 'on schedule', the most important developments in nanobiotech will be impossible to know until it gets here.
  • Knowing how project managers tend to exaggerate product schedules, I'm thinking that such innovations, if they come, are probably four times the estimated dates away... which places them securely outside of my lifetime. :) --Ray
