Not since the inductor was discovered has there been such cause for rejoicing.
My guess is that people in this glorious new age will continue to be, by turns, noble, venal, kind, warlike, selfish, generous, stupid, wise, thoughtful and ignorant, and that life will go on much as it always has.
I find it hard to believe that this discovery/invention (as opposed to, say, the transistor, fission, the steam engine, the telegraph, quantum mechanics, et-bloody-cetera) is really going to alter the human experience for all time.
We will, however, have smaller iPods. And this is a cool discovery.
From a narrow, self-interested perspective, I wonder if this will end up having any impact on how computers look to the programmer. I'd guess not; I think this stuff will be used to make faster/smaller versions of what we already have, in much the same way the last 30 years of advances in processor design were used to make really fast IA instruction set chips. If I'm wrong, though, it'll be interesting learning how to program the things.
