Drexler has calculated that all the brains that have ever existed before humanity, that is, all the brains since brains were invented in the Cambrian Explosion 570 million years ago, performed the equivalent of about 10^38 machine instructions. A Nanotechnology computer the size of a large present day factory and using no more power, could perform 10^38 machine instructions in about 2 years.
