Arthur C Clarke predicting the internet:
The other side of it is that if you inspire kids with sliding doors and communicators and robots that talk then they'll spend their lives trying to create such things. It might not only be about prediction, in other words, but inspiration.
e.g. Skynet appears in the Terminator films - quite possible that it will appear for real as it is one of the things people think of as being possible. Even with negative ideas, some clever idiot will be the one to make them real.
Another interesting one would be Philip K Dick's "A second variety" which could give lots of people silly ideas that would end us.
