This Could Be Big

Ir probably will be -- computers that operate on light:

Researchers at the University of Pennsylvania have made an important advance in this frontier of photonics, fashioning the first all-optical photonic switch out of cadmium sulfide nanowires. Moreover, they combined these photonic switches into a logic gate, a fundamental component of computer chips that process information.

The nano-wires can manipulate light to make switches, the basic component of computers. Did you get that? Nano-switches. As in really, really, really tiny.

Vernor Vinge wrote a novel a few years ago, Rainbow's End, that postulated people being able to access the Internet through their clothes. Sony, I think, has already debuted a prototype of a computer built into eyeglasses. With this, they could build computers into contact lenses.

It's an amazing world. It's sort of sobering to realize that we're living in a science-fiction novel.
