Anyway, Carmack knows a lot about optimizing computations on modern hardware. In practice, that happens to be also necessary for AI. However, it is not __sufficient__ for AI.

This is exactly how Science works. He’s right until proven wrong. And so are you.
"He has built an AI system that fails to do X."
Perhaps you have put your finger on the fatal flaw ...
