Furthermore anyone who studied branch and bound in algorithms class ought to understand that a chess engine wins games but does not understand the game and cannot explain the game. That's partly what Chomsky meant by explainability; the fact that AlphaGo/MuZero can beat humans at chess says nothing about rational intelligence any more than a conventional chess engine can beat humans says anything about its capacities. It says even less because a neural network obscures its own learned algorithm, by design.
