C++ pushed assembly down to a footnote. It didn't kill the craft of engineering, it moved it up a level. AI does the same thing to making games. The low-level work gets cheaper, and the taste, the structure, and the judgment matter more, not less.
Zipix is a live micro-game studio I built solo, AI in the loop end to end, before hiring anyone.
A player gives maybe a tenth of the effort to play a thing that I spent days making. The moment a thing is cheaper to generate than it is to play, the player feels it, and they're right to. AI is leverage on effort, never a substitute for it.
I'd use it to put a small team's leverage in every maker's hands, and spend the time it frees on the decisions only a human should make.
