>The idea that technological advance is as inevitable as a law of nature is a fallacy. It usually relies on us getting lucky because somewhere an enabling technology or knowledge was discovered. [...] American Indians never discovered a wheel, by the way.
Actually, the Aztecs *did* invent the wheel. It's just that they only used it for toys. Why? No horses. Go read Guns, Germs, and Steel. Technological advances do rely on *somebody* *somewhere* getting lucky, as well as a social/economic/technological system that can exploit it. With as large as the world is now, that might not be much of a problem. There is a lot of room for new memetic mutations, and we have a very complex ecosystem where new advances can take root.
>Moore's Law is already at its limit. The next step is two-prong: parallelism and hybrid (analog-digital) chips.
Not quite. Moore's Law is about number of transistors per area, not clock speed. I realize I'm slightly out of touch with computer technology, but last I checked, Moore's Law is still holding, even though clock speeds have topped out. Hence the drive towards parallelism.
