True, but search algorithms are the foundation for most game playing AIs. What I would take out of this is that there is a missing component that would bridge specialized AI to general purpose AI that mimics humans. For example a trained professional player is aware of the history of plays prevalent to a game and I doubt most professionals can/eventually invent new plays, and this affords by-passing the brute force millions of games needed to train an AI.
