In 1989, Gary Kasparov said that it was "ridiculous!" to suggest a computer would ever beat him at chess.

"Never shall I be beaten by a machine!”

In 1997 he lost to Deep Blue.

And today he's got salient observations on politics which hold much of his attention, and Deep Blue is shut off and has done nothing further.

Not a good argument for turning everything over to the Deep Blues. What's Deep Blue done for me lately?

Yeah, and back then people moved the goal posts too, saying Deep Blue was just "brute-forcing" chess (which isn't even true since it's not a pure minimax search).
