I don't know. I'd say Orwell did an excellent job of predicting North Korean society.

1984 is not really science fiction, but a political fantasy showing the worst a society could become with modern technology. As with all dystopias, it is a warning more than a true and consistent world.

I co-ran the UC Davis branch of the Students for an Orwellian Society 10 years ago. The idea of doublethink, of encapsulating dangerous ideas in pithy slogans, of massive government surveillance -- those are all very relevant today. They serve well for helping to frame a debate. But still, I've never felt the urge to reread 1984, which in some ways proves Asimov correct. It's not amazing as fiction, but full of interesting ideas.
