In addition to Baldi's overestimation of memory requirements that you've
generously taken to the time to point out (thanks), Baldi's reference to
"current rates of memory storage advances" fails to include a recent discovery
concerning a new kind of computer memory:
Non-metallic magnet could be dream computer memory

Useless hypotheses, etc.:

analog computing, cultural relativism, GAC, Cyc, Eliza, cryonics, individual
uniqueness, ego, human values, scientific relinquishment, malevolent AI

We move into a better future in proportion as science displaces superstition.
