Refer to my point on past inputs. If a human suddenly said to the machine "change of rules, now you have to play by these new rules" the AI suddenly gets immensely dumber and will apply useless solutions.
This no longer appears to be the case. Self-trained systems, that play themselves extremely rapidly and can even infer the rules by encountering just notices of illegal moves, are now commonplace.
How is that relevant? A human will also get immensely dumber. Of course a lot less then an AI right now. The point is AI absolutely can do things a human can't.
