Nanotech: In the Stone Age
Chris Phoenix: Today's nanotechnology and stone-age flint knapping can be compared on several levels. Most trivially, both involve the production of extremely small features. But the correspondance goes pretty far beyond that--and, as you might expect if you've been reading this blog for a while, molecular manufacturing comes out looking quite good in comparison to present-day achievements.
