nanomancy

[jodawi]

I irk at stories treating nanotechnology as magic, where little bots can do anything at all with seemingly unlimited power. This ignores the fact that nanotechnology already exists and is quite constrained: it's called life. If you don't see living things doing what you want your nanobots doing, and doing it as quickly as you want your nanobots doing it, then you're probably misunderstanding how powerful your nanobots can be.
