It's not about machines taking over the world... it's about a future society where there is pretty much no privacy and "Big Brother is watching"... pretty good book. You can pick it up at a used books place for about 50 cents.
Damn... book piracy, the lazy man's library is the internet. I have like $500 credit at the used book store so I get my books, games, and movies for free. Yay me!
