As for the possibility of a human mind residing somehow in a computer, we need a little reality check. Some members of the AI community (proper) simply scoff at Kurzweil's optimism. I used to work in AI, Rob. This happens to be my second (or is it my third?) cybernetic revolution.
As any mainstream AI person will tell you, there hasn't been one iota of real progress in the area of mimicking human intelligence since Terry Winograd's SHRDLU in 1968. Since then, AI has been developing expert systems and various kinds of "smart" (not "intelligent") agents in software applications.
Radical AI proponents Marvin Minsky and Hans Moravec may be in universities and they may get on TV a lot, but I'm just amazed that the media doesn't realize (or unconsciously covers up the fact) that these guys represent about 2 percent of the whole AI community and outside their circle, they're simply not credible.
I'll repeat that for anyone in the media looking in: There has been no scientific or technical breakthrough since the late 1960s that would justify the current (X-Files driven) intelligence-in-the-machine fad. There, that feels better!
