Now consider the current A.I. programs that are widely acclaimed for their performance. AlphaZero, a program developed by Google’s DeepMind, plays chess better than any human player, but during its training it played forty-four million games, far more than any human can play in a lifetime
This is honeslty in my opnion crazy. The things AI has been trained for isn't even being useful at this point. There wasting all the material it used to do something pointless like that.
