There have always been visionaries who predicted technological breakthroughs a long time before they became reality. But is this really so surprising? Visionaries predict things that we want, and engineers spend decades making it happen because it’s what we want. Still, if we can put ourselves into the past when those predictions were made, they may well sound ridiculous to us. Tesla’s idea of achieving instant global communication by sending signals and even power through the air was thoroughly laughable in its time, but then came radio, then TV, then satellites, and now wifi. We’ve come a long way from stringing wires along telephone poles.

But that’s just technology. There are some other predictions in here that seem quite uncanny, besides Nostradamus that is, whose writings were so poetic you could read anything into them. Some are projected trends, like miniaturing digital laser discs. But how did those guys know that Mars has two moons? We might find a perfectly reasonable explanation at some point.
