Ironically I had a very smart and otherwise reasonable math professor who, shortly after Kasparov lost to Deep Blue, said in class that chess was no longer interesting.
It's possible. At that time people were talking about Go as the next frontier (that didn't last long). IMO, the game is the same, and for 99.9999% of folks who ever play it, whether a computer can beat the best human is irrelevant in how fun it is to play.
