Improvement through self play requires a different kind of search from game tree search, a search which explores variations of the self. I pointed out the possibility of self reinforcing blind spots long ago. In fact, I suggested the possibility that AlphaZero Chess reached a self play plateau that could not beat a version of Stockfish which used an opening book and endgame table base. I am unaware of anybody else suggesting that.

One possible response to plateaus and blind spots is to increase the search during self play games. I had that possibility in mind when I said that correct play could be found in infinite time. ;) (Not that I would take that approach to overcoming the currently identified blind spots. :))

People used to be pretty worried about self-play plateaus until AlphaGo Zero came along and slaughtered all the top pros. :) But they may have been too quick to stop being concerned about it.

Well, if your goal is just to beat all humans, what's the problem? ;)
