[math-fun] AlphaGo Zero

Just because AlphaGo Zero can beat its predecessor, which in turn can beat expert humans, does it follow that AlphaGo Zero can beat expert humans? https://www.quantamagazine.org/artificial-intelligence-learns-to-learn-entir... It seems possible to me that AlphaGo Zero could be exploiting weaknesses in AlphaGo that humans might not share. It's not obvious to me that transitivity applies in this kind of situation. I was surprised that Kevin Hartnett didn't address this question. (Or am I missing something?) Jim Propp
