If you took a time machine back to 1921 and asked an American what life would be like in 2021 you’d get some wild guesses, for sure.

Some may think that a Metropolis like future was a sure thing.

But, no one would have guessed:
1) nuclear weapons;
2) Bitcoin;
3) Donny and Marie Osmond being nostalgia figures.

Point being: the future is hard to predict.
