I have read the following: We 1984 Brave New World I am wondering, which do you believe will be most predictive of the late 21st. Century future? If not one of these, which?
I always liked Huxley's A Brave New World. I read it many years ago and reread it a couple of years ago. I haven't read We but have read 1984. Of the two I think Huxley's work has aged much better. 1984 feels very much a product of it's times and in a sense outdated. Meanwhile with Huxley's novel a lot of the concepts feel more relevant. We might not be genetically programmed, but we certainly are being trained to consume more and more goods. Often times things we don't even need. He really had some good foresight and thoughts of the problems future societies might face. If you enjoyed Brave New World them try reading Island, also by Huxley. He also has a Brave New World Redux which is a collection of essays on problems he envisions societies will face. He goes into a lot of the things he wrote about in Brave New World.
This may sound weird, but I don't think Isaac Asimov was too far off with his Robot and Empire series. Think of it. Overpopulated, sick world in the future where people are clamoring to settle other worlds and those left behind get too attached to robots/conveniences. We almost have that today.
Take a look at The Machine Stops by E. M. Forster. It describes a world in which direct human experience is completely marginalized in favor of mechanized predictability. Spontaneity is non-existent; routine is everything. To question authority is to commit a crime. The pursuit of intellectual knowledge is abandoned in favor of the rehashing of knowledge already gained.
I just read "Super Sad True Love Story" by Gary Shteyngart. It won the "Bollinger Everyman Wodehouse Prize" for comic literature (comic as in funny, not as in comic books) last year, but I found the book very depressing and frighteningly possible -- I think it qualifies as dystopian.
