What Can Nanotech Do for You?. Nanotechnology for computing, for human bodies, for everything. Perhaps this all is hype, perhaps not. However, I believe progress is achieved with small steps, so it is not much use to speculate about the promises of nanotechnology in a 5-10 years timescale. Those of use who are then alive will see fascinating things, and usual things, but nobody now knows what will be the big new thing.
