In 1964, at the New York World Fair, Isaac Asimov wrote an essay predicting what the world would be like in 50 years.

While some of his predictions missed the mark entirely (eg he predicted that there’d be colonies on the moon, but that Conversations with the moon will be a trifle uncomfortable, but the way, in that 2.5 seconds must elapse between statement and answer (it takes light that long to make the round trip).) it’s surprising how close some of his predictions were.
