Tbh I'm not very concerned. Unlike chess, which has very finite state, the "build something appealing" kind of game has a very vast amount of state. And the current architecture of LLMs doesn't make them very "creative" (whatever you define it as). If given a scoped task, they'll relentlessly try to complete it but the design, as we speak, is still your job. You can get AI to clone something already existing, which does decrease moats, yes. Making it do something new is way harder.

All those one-shot games and product demos are clones of existing things, and while they're very impressive, they aren't exactly new ideas, you know?

Of course all this might change and the labs might figure out the secret to creativity, but as things stand today, humans can keep "moving up" the value stack to just make more complex things.
