nanobiobots

Salon - I, Nanobot

Nanofabricated animats may be infinitessimally tiny, but their electrons will be exactly the same size as ours -- and their effect on human reality will be as immeasurable as the universe. Like an inverted SETI program, humanity must now look inward, constantly scanning technology space for animats, or their progenitors. The first alien life may not come from the stars, but from ourselves.
