I'm a Vonnegut fan -- who isn't? I was talking with a librarian in my neighborhood about how thrilling it is for her to introduce young adults to Vonnegut. I'm jealous that she gets to literally activate dormant minds.
Does the book address the shut-in geek archetype? It's interesting to see how different authors and thinkers take different directions with these technologies. Gary Shteyngart is known primarily as a humorist or satirist but his vision of 3D projection devices displaying their owners' health and financial information in the air, constantly rating them against everyone else in the room and issuing 'hotness' and 'dateability' rankings in real time, etc, sounds pretty close to accurate. He also sees paper-bound books and literacy going away by 2020 or thereabouts :).
@Shepy Yes, yes I have read that one, I picked it up last year just after it came out. Aside from being packed with 80's geek nostalgia it does have some interesting ideas on one path society could take.
So everyone else out there, I concur, it's a great book, go and read a copy.
