From an art perspective, AI seems to be quite a ways away from someone being able to make a coherent general game.

The self-consistency just doesn't seem to be there to make a coherent playable game (easily, broadly - many types of games, styles, etc).

Music gen AI is pretty good, and with a reasonable amount of finagling, you might be able to pull that off generally.

From a coding perspective, you can probably make simple games with minimal skills already, and I can definitely see it being possible to create pretty sophisticated games with minimal bugginess with minimal coding skills in the near future.

Is that combination good enough? I doubt it outside of niche games for quite some time
