  1. Nanotech is already here... by StevenMaurer · · Score: 5, Insightful

    You have it in your PCs and disk drives. This form of nanotech has a bright future.

    What isn't here, and probably never will be, is the SciFi "self-assembly" nanotech. Throw out some powder on a rock and watch it turn it into a new car. Or something equally silly.

    Strangely, we don't expect steam shovels to make other steam shovels. We don't expect cars to run without gasoline. And we certainly don't expect it to all just work without breaking down. But make the robotics very very small, and suddenly magic is supposed to occur.

      We don't expect beach balls to be on both sides of the net at the same time, either. Make robotics very small, and it's not magic, but quantum effects and scale-invariance, that occurs.

      There already exist entitites that make others of their type, operate on chemical energy from the enviroment, and are self-repairing. We call them "bacteria".

      It is not unreasonable to expect that at some point in the future we will be able to create machines with these characteristics.

      Yes, it's silly, but not all that unique...

      Remember all through the 70's and 80's we were got bombarded with theories about how artificial intelligence would revolutionize our lives. According to some people we should already be interacting with our computers as though they were humans by now.

      Two things drive this sort of phenomena. One, we WANT to believe in these things. AI, Cold Fusion, Nanotech, Alien from another planet, etc, all have the potential to revolutionize our lives and change human history. Secondly, our desire to believe is great fodder for anyone trying to sell and idea to venture capitalists. With so many media outlets and ways for people and companies to self publish, is it any wonder that these concepts keep getting floated over and over like a dog chasing it's own tail?

      Someday, maybe, some investor(s) will get rich on nanotechnology, but in the mean time much money will be spent and produce no usefull results, and all the while we will continue to ask ourselves "why can't we cure ____, or feed the poor, or bring the price of energy down by ordinary means". Hopefully the funds we devote to far-out possibilities will be in proportion to solutions that are right in front of our face, but lack the pizzazz of these sci-fi concepts.

      maybe we are not talking about the same thing.

      "nanotechnology" and "molecular assembly" are not the same thing. this is important, because the field of "nanotechnology" has already made some very interesting and practical discoveries, particularly in material science.

      the subset of "nanotechnology" known as "molecular assembly", on the other hand, has made very little progress. i suspect that this is what you were referring to.

      the distinction is important.

    She sure didn't say much, but then the questions weren't exactly thought provoking and the answers were likely trimmed for space. I am glad there is attention and concern about the long-term affects of nanomachines, rather than complete focus on the short-term results possible.

    Personally, I think Sci-fi does a better job of presenting the many possible hypes and fears about nano-machine than she did, and the many ways of handling the issues. It seemed like she was trying to prevent public rejection of nano-technology by providing the most minimal information possible. What sort of controls is the FDA looking at? How does she propose to prevent the problems the public fears most?

    ... but once business gets a hold on it, that idea will be laid to rest. Heck, why worry about nanos when we already have increasing lead, mercury and other toxins to deal with? Just another way to destroy the planet.

    Seriously, though, it is good to read a nice boring article about any technology. It seems like the average dolt has to have something blowing up or a mass kill in a story before they bother to read it (or more likely watch it) anymore.

  5. "A good, balanced read"? by Deskpoet · · Score: 4, Insightful

    The interview of a person who's self-stated goal is to "to draw attention to proactive, responsible development" (i.e. media flack functionary) appears in Businessweek, a magazine with a natural pro-business "bias", and you call it "a good, balanced read"? So I imagine you decide (affirmatively) that Fox news is fair and balanced, as well.

    Is it any wonder that the average American is a moron? Critical thinking doesn't live here anymore.

    As to the actual merits of the article, I found it to be a puff piece, with lots of whining about the failure of industry marketing to overcome resistance to wonderful technologies like GMOs (the frightened herd avoids the blame, and, to her credit, she avoided the word luddite.)

    Where's Scientific American when you need it?

    New materials, new compounds, new chemicals need to be PROVEN to be safe before they are let out of the lab
    Unfortunately, you can't prove anything is safe. Primarily since you can't predict any of countless number of variables and reproduce them in a lab. Even if you test on 1000 human subjects, you might later find out that one human in a million has a fatal allergy to something.

    At best, you could perform a battery of test on animal subjects and look for adverse reactions, like is done with new drugs. And even then, occasionally a dangerous one slips through.

  8. more misunderstanding of nanotech physics/chemistr by Daetrin · · Score: 2, Insightful
    Wow, so much mis-information. You're right that designing nanotech that would be able to survive and reproduce in the world would be difficult, but if that hurdle was passed they wouldn't be as easy to destroy as you make out.

    They're not going to rust. First of all, they probably won't be made out of iron, they'll probably be made out of carbon, oxygen and hydrogen. The chemical bonds that are necessary for oxidation or any other kind of reaction are already being used to attach the various pieces of the nanotech together. If there are no free electrons or "holes" nothing else is going to latch on. In effect, it's already "rusted."

    What makes you think they'll have computer circuits that could be affected by an EMP? They could just as easily be using rod-logic or something similar.

    As for "diamonds" being brittle, not at the scale we're talking about. The type of sound waves needed to break carbon bonds at a microscopic level would destroy just about anything else as well. What do you do if a person gets affected? Shooting at them with a beam of something that breaks all carbon bonds is _not_ a good solution.

    Why would moderate temperature changes cause them to break? You can get large structures to break by changing the temperature repeatedly, but that takes a long time, and it's because of the aggregate expansion of all the molecules inside. Small structures, such as the cells of our body for instance, don't fall apart from the stress of small temperature changes. You can denature proteins and set stuff on fire if you make things hot enough, but that's because of chemical changes, not expansion/contraction.

    Oh, and depending on the nature of the nanotech "reprograming" them might be difficult or impossible. They might only be capable of the specific task they were designed for if they have physical logic rather then reprogramable circuits. That would make terrorism much harder, up until the point technology advances enough to let anyone with a home lab cook up some nano-tech. In terms of grey-goo the biggest threat will probably be programming error, followed by mad scientist, followed by terroists.

    Of more pressing concern is possible enviromental dangers (potentially very serious when one of the possible enviroments is your body) and smaller malfunctions. It's a quite possible for nanotech to screw up and kill you in a way that doesn't involve grey-goo or threaten the rest of the planet.
