LLMs show the problems of energy economy in this form of computing. It costs way too much in resources and power for minimal and generally worthless results. 2048 is a game with a several known algorithm for winning. Tetris is an obscenely simple game that unassisted humans could reliably take to the kill screen 20 years ago.

Does any of this used energy benefit any other problem?

Also using "Superhuman" in the title is absurd given this paltry outcome.
