My initial thoughts were, "No, of course not! Cars and trains didn't kill track-and-field competitions!".
But now that I think about it, I really do feel a slight aversion towards getting back into chess.
Although practiced concentration is a side-benefit of playing chess regularly, the fact of the matter is that nowadays, it is impossible to play in a manner that hasn't already been thoroughly examined by some AI.
There's no new ground to discover; no interesting techniques or thought-processes that an amateur or a world champion can invent; there is no more sense of human innovation in the game.
If I picked up a chessboard for the first time in a decade, there would always be a chance that I can come to defeat Gary Kasparov someday; that is not the case with AlphaZero or DeepBlue.
Say what you want about the benefits of forced concentration or the social benefits, but that desire to play chess has been extinguished for me, and I'm sure for many others, once AlphaZero and DeepBlue hit the scene.
