Chess engines aren't a done deal. Besides NNUE (which I would consider more general) that are outright better than handcrafted eval functions, the dust hasn't settled yet between the more specific AB pruning stockfish vs the more general MCS lc0. Yes, stockfish has been generally slightly stronger, but in the near future with better NN architectures I could easily see this changing. And even then, chess is probably an example of something very narrow that you can deal with specific methods. Humanoid robots are probably the opposite, and you probably need AGI for them.
