It's not like someone is going to prompt up "gimme GTA7 based on what you know about all the past GTAs" and similar crazy high level instructions in a few weeks and go, "yep, that's our standard". There are almost certainly thousands, if not hundreds of thousands, of little decisions that go into producing something so massive in scope. Anything that could significantly speed up prototyping, world building, character modeling, NPC behavior, etc, should be seen as a massive boon, and probably the shot in the arm the video game industry needs.
And I have the same critique of premium streaming series. Vince Gilligan likes to extoll the benefits of not using AI at all in producing his work, but then he gives us a potentially 3 year span between seasons of his latest entry... where not a lot happened, because it's almost entirely chewing character dev stuff. The idea that a 5-6 season show might take longer to complete than seeing a child born and off to college is absolute bonkers.
