  1. Re:Giving a man a fish vs. teaching him how to fis on Remote Control Robotic Snakes · · Score: 1

    I think the difference between our points of view is that I believe that we have to use nature to get by it while your opinion is that we can blow right by it to something better. Do I sound about right?

    The real difference is that I'm doing research in distributed computing, so to me anything is an excuse to push a distributed computing effort... :)

    Your points are valid, of course, and so is biomimetics-oriented research. My point is simply that, knowing that technological advances usually come much faster than you expect, it's imprudent not to start preparing already, at least in terms of infrastructure, to support future research on what seems to be a very promising field once we have the technology necessary to do it well (i.e., computing systems that are able to simulate real-world conditions with enough detail that it's possible to perform automated selection between different "individuals" based on their performance in the simulation).

  2. Re:Giving a man a fish vs. teaching him how to fis on Remote Control Robotic Snakes · · Score: 1

    I disagree.

    I knew somebody would... :)

    There's a lot to be learned from the biological nature of things.

    Of course there is. I never disputed that.

    The most successful models and robots that have been developed so far mimic things found in the biological world. For example, distributed learning and mechanics is what ants and bees have learned to do. If a single ant or bee finds a source of food or pollen, chances are that in under half an hour, there will be a lot of its friends there. Big clunky walking machines are not the way to go: lightweight machines which have a single joint like the human knee are what works.

    I'm aware of all this research. But it all depends on your definition of "successful". So far you've missed my point.

    Or, make a robotic model like a cockroac h and you'll find that you can move and get over obstacles better than anywhere else. And if you want to move in water, you should learn to swim like a tuna.

    "Better than anywhere else" is subjective. It's good, yeah, but who says that there isn't a much better way to do it that no engineer has yet figured out, but that, say, a distributed computing effort applying an iterative recombination/mutation/selection algorithm over a design for a locomotion system might find really quickly?

    This is all practical research done at MIT right now with proven results.

    Yes, I'm aware of that.

    It's far more promising than trying to engineer something from scratch.

    Again, that's questionable.

    Nature has millions of years worth of R&D to develop its solutions. Why not tap it?

    I didn't say we shouldn't tap it. What I said is that, when designing technology in the future, we should not confine ourselves to the examples provided to us by nature - especially not if we ever intend to move out en masse towards new environments in which natural biological evolution hasn't produced useful design paradigms. Nature may have had millions of years, but nature's iterative cycles are slow, while ours needn't be. With increasing computing power, it's not inconceivable that in a short time we may be able to perfect GA-based systems that spew out completely innovative designs ready for incorporation into new technology - and why not, even entirely artificial machinery nanobuilt directly from computer-generated specs.

    So it's not a question of "what research path can produce results?", or of "what has produced the most useable results so far?". It's a question of "what is the most promising path in the long term?" For now, we're still playing catch-up, but eventually, we'll outrun the natural evolutive processes, and then there'll be nothing left to copy.

  3. Giving a man a fish vs. teaching him how to fish on Remote Control Robotic Snakes · · Score: 3

    Although this is a pretty cool engineering feat and will probably eventually become useful, I don't consider it to be very meaningful in the Big Scheme of things. IMNSHO, biomimetics is the result of people getting what is essentially the wrong message from nature.

    What I mean is: people look at, e.g., a snake moving around gracefully, and they say "Let's replicate that kind of movement! It'll make for very useful robots!" So they go and study snake physiology for years on end, eventually mapping down the entire motion mechanism. Then comes the hard part: they try to build an artificial motion mechanism that works on the same principles. This proves incredibly frustrating, and it takes a Long Long Time and plenty of irritating compromises before someone comes out with a workable design - which will likely resemble the original in very few aspects. In effect, they're just trying to reverse-engineer a finished product [1], knowing only assembler code and nothing of high-level programming.

    Now, I think a much better way to do things is to notice, instead, how incredible it is that such a powerful and versatile, while buggy, mechanism has arisen from just a few organic molecules without external intervention [2], and to concentrate on learning how the evolutionary process works - and to try and mimick /that/. This may not (in fact, it probably will not) produce motion mechanisms that are identical to snakes', but it will at the very least produce systems that are equivalently adapt at moving in the same kind of environment. Not only that, it'll also provide us with an endless source of new ideas for systems and of insight as to how to design better ones. In effect, instead of copying nature's mechanisms, we are learning to program for ourselves.

    Of course, I'm aware that many steps have already been taken in this direction (the GA-designed Lego Bridge comes to mind), but GA-based tech is nowhere near as popular a research field as traditional biomimetics.


    [1] Yes, I know, nothing in nature is a "finished product". I just used the term for the purpose of analogy.

    [2] ... which is what is generally thought to be most likely to have happened. Before you try to assert that there was any kind of external (external to the environment - i.e., supernatural) intervention, let me tell you that extraordinary claims require extraordinary evidence, and until I see some of it, I'm sticking with the strictly-natural theory.

    In general, I agree with Katz's analysis of why the intelligentzia's anti-technology stance is ultimately doomed. However, to make his point, he may be getting to wrong conclusions from the survey's results. As he says:

    What's striking about the survey is that although Americans expect some problems to worsen, their overall outlook about the future remains optimistic.

    Or maybe they just don't think much about the issue, and just get enthusiastic - rapidly sweeping into near-hysterical herd mentality - when both the good and the bad are brought up.

    Here's how these pollings often go...

    Q: Do you think technology will improve our lives?

    (Subject very cheerful, thinking about all the great advances of the 20th century, presumably desiring to make "a good impression" on the poll)

    A: Yes! The 21st century will be wonderful! With robots and flying cars and all.

    Q: Do you think that {there'll be an epidemic|there'll be a terrorist attack|world hunger will agravate|the environment will go down the drain}?

    A: Yeah! I mean, the global warming... and the Muslims with the nukes... and those poor Ethiopians... and AIDS and Ebola... [et cetera, ad nauseam]

    See my point?

    Also, Katz displays an amazing amount of Americanocentrism. It's very strange that, times being what they are, a journalist discussing a theme of universal interest in an electronic medium with worldwide reach, takes as universal data that pertains only to about 4% of the world's population. This is a very strong and noticeable tendency in Katz's writing. So travel a bit, Jon.

    And just how do you propose to do this?

    We'll start by inventing a practical assembler technology and forming an underground movement to give everybody in the world access to it. Free assembler technology means virtually infinite resources, which means that everything upon which our current economic model is based upon comes tumbling down. As the human species becomes economy-less, it also gradually becomes politics-less (this is a process we can try to speed up). "Social" crime and violence vanishes, and there is no longer a need for law per se. As governments break, we then make a massive effort to make people conscious of their own freedom - people no longer have economic shackles holding them down, and they should be able to do whatever they want without having Big Brother always breathing down their necks. What this really means is that it no longer is valid for any group of people to try to hold a monopoly on authorized violence (which is the best definition of a government). We also spread the idea of self-regulation - eternal vigilance to guarantee one's own freedom. As life conditions improve drastically, people have no need for a government per se, but only corporations to take care of their bureaucratic needs - life insurance, etc. Because there are no governments and everybody is free, corporations are no longer able to gain power in ways that harm consumers (directly or indirectly). So we have anarchist capitalism.

    It's a nice idea, and the only thing upon which it really depends to work is the technology. We'll see what happens in the long run.

    The last fellow to proclaim himself independent of the law lived in a compound in Waco, TX. Last I looked, he died, his followers died, and just to be sure, two dozen children died in a fire.

    Wow. You know, you're right. Two dozen children died, so we should stop trying to free ourselves from tyranny. Because that's the fate of everyone who attempts to break free - or who questions the morality behind the idea of government.

    Maybe you should research the histories of the men who signed the Declaration of Independence. They were killed, their children killed, their homes and farms burned.
