I just finished "Player Piano" by Kurt Vonnegut... it was really good. I also read "Blondie24" about how 2 guys made an AI program to play chess online and became really, really good. (Not like Deep Blue which played chess based on an array of pre-programmed moves, this machine actually learned while it played and ran off a home computer, not a super computer)
Also, it may sound weird, but we've been reading some good stuff for Humanities lately... Frankenstein, Schiller's 'The Robbers', Goethe's 'The Sorrows of Young Werther', and Voltaire's 'Candide' to name a few.
Next up: "AI Game Programming for Windows" and Bruce Campbell's autobiography "If Chins Could Kill"
I also HIGHLY recommend anything by Issac Asimov. The Foundation Series was astounding.
