I rather doubt it. But with information technology increasingly in the hands of ordinary citizens, and good communications every which way, we at least shorten the odds on having democracy. Look at what happened in Russia. In the late Soviet Union it was communications which enabled the revolution to take place. It's not a function of the genre at all, as I've always been careful to point out.
Science fiction is, one, entertainment, and two, extrapolation.
I always deny being a prophet, except to a very limited extent in non-fiction and in technology. But it's only fair to say that when science fiction does go in for prediction it's not always wrong. It's usually wrong. Although it's much more right than any other form of fiction. The other side of this coin is the assumption, often made by non-sf readers, that technology has advanced to such a level there's nothing left for the genre to explore.
