I agree that AI is not as good as people at being entertaining. And everybody looked at putting LLMs in their games as GDC circa 2022 or so. It seemed like a good idea until you realized the server cost or the performance hit. So this is right.

But.. as someone who works in the business of games.. how sure are you that AI hasn't been there all along in ways you may not realize? Companies are very disincentivized to let you know when they are using it.
