Query: GOOD INTRO

Mr Kurzweil is the Carl Sagan of the A.I. community. If you haven't already read "The Age of Spiritual Machines" and you're interested in A.I. then buy the book. Mr Kurzweil (as many have stated) is too optimistic and does largely ignore the political and behavorial tendencies of us bags of water but that doesn't make it any less an enjoyable and informative read.If you want to read the possible bad outcomes, read the Unibombers Manifesto. It's too bad he's evil and crazier than Michael Jackson because it's an interesting read.
