Kilian Weinberger's 1st lecture on YouTube.

1956 (or 57) the perceptron was made. The public mood was ecstatic. Generals were dreaming of robot armies, finance world was dreaming of automation, and the whole world was dreaming.

1964 (or 66?) a bestselling book was AI Winter. It explained in everyday English how the whole thing was a farce (at that time). Funding dried up. It wasn't sexy to say AI anymore. So people started saying ML. For funding they were doing ML and not AI.

Nowadays it is a top down vs bottom up approach. One is AI and the other is ML (i don't know which, it doesn't matter)
