It's been written at length here and elsewhere by game devs, but this isn't a thing that anyone would truly want. A purely AI generated or controlled world would have no constraints, and be fundamentally untestable - games aren't really games unless they have constraints. Even the 'purest' sandboxes have some kind of constraint buried within them, and I think you'd find an RPG of this type extremely boring, at least with current technology.
