I may take a slightly different view of nanotech than others, and than Drexler. Naturally I've read his books. One of the most notable lacks in all his discussion was actual designs of objects which could be built now or very soon. The way to get completed nanotechnology is not to sit and theoretically work out its limits, but to try to make actual small devices which do useful things ... and make them smaller and smaller and you continue. The trouble with theory is that the theoretician is likely to forget something, no matter who he is. If he has actual working devices, even if they don't come up to theory, then he can test his theories and their merits, but without them he can only sit and think, and maybe make crucial mistakes ... which no one notices until they actually try to MAKE SOMETHING. These ideas tell me that what's happening in nanotechnology is all to the good. On chemical levels, means to cover something with better paint ARE forms of nanotechnology, just as are many other things, such as novel materials like the kind people have make flat TV screens right now. And even more is coming down the line. We may or may not get the nanotechnology Drexler writes about. That depends on whether he really did escape critical errors which we will only discover as we work in the field. I have my personal opinions about possible errors, but fundamentally they too are only theory. We should make real machines even if they don't equal our theoretical limits, and see what happens as we continue. Best wishes and long long life for all, Thomas Donaldson Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=18595
