I think competitive sports are and always have been about competition between humans, and I don't believe that the ability of a machine to play chess better than any human changes that, any more than the fact that, say, a hare can outsprint a human, or a horse outrun one in any middle distance, makes foot racing intrinsically uninteresting. In addition, humans enjoy playing games, and I think this extends to watching or following other humans who are better at it as a vicarious means of participating. A Saturday poker game with your crew is not diminished by the fact that everyone in the game would be slaughtered in a professional tournament, nor is the fun of watching said tournament diminished by that knowledge. I can enjoy a game of flag football with my family, and still enjoy an NFL Monday Night game, even though no one in my family would last 2 plays in the latter.
