What Are Science Fiction's Best and Worst Predictions?

Sometimes scifi foreshadows the future with incredible accuracy (the fiction of Jules Verne, for instance, predicted the moon landing and the electric submarine) and sometimes not (he also imagined an Earth that had a core full of mastodons.) Today, we want to know your picks for the best and the worst predictions about the future from science fiction.

Tell us in the comments below just which scifi predictions have already proved remarkably accurate (or woefully misguided) and who it was who made them. Pictures too, please!
