That is as long as the recipient has a nanoassembler and some spare matter to feed into it. The nanoassembler would be a kind of desktop manufacturing unit. It could receive a genetic recipe by e-mail for a flower arrangement. Still, it's today's computers begetting tomorrow's thinking computers, today's nanoscience leading to nanoassemblers. Perhaps everything has already been invented, and now we're just filling in the niches with style.
Mechanical breakthroughs are part of the Industrial Revolution.
We've moved beyond that stage and so has the leading edge of innovation. Not Stanley Mason. And that's in the early stages of nanotechnology development. Further down the road, nanotechnology could make everyone an inventor on a daily basis, with virtually all products customized for personal use. It's enough to send a chill through the average 20th centurist who still has trouble aligning the pattern on new wallpaper.
