you all should try to find a copy of Earth Abides, by George R. Stewart. Written in 1949, it gives one vision of the future...and what amazes me is no matter how many times I read it, there is no way I can tell that it wasn't written today......
Earth Abides won the International Fantasy Award in 1951, is included in Science Fiction: The 100 Best Books by David Pringle (both editions), was included in Locus Magazine's All Time Best Science Fiction Novels in 1987, and was a Prometheus Hall of Fame Finalist in 1990.

1998 review of Earth Abides
It is ridiculous to set a detective story in New York City. New York City is itself a detective story...
