The best description I've ever heard of AI is the following. I heard this in the 80s, and it has held up since:

AI is magic.

1: You see a magic trick. You are amazed by the magic.

2: You are shown how the trick works. You are impressed by the technique.

3: You learn how to perform the trick. Now it's not magic, it's sleight-of-hand, or mirrors, or misdirection.

This is why "AI" is always bullshit: once you understand it, it's not AI any more, it's something else.

@jwz Also interesting quote from a guy named Isaac Asimov: "... an uninformed public tends to confuse scholarship with magicians..."
