Funny thing is lot of people love Main Menu music - great music/voice - I'm sorry to burst your bubble, but it's AI.
I always suspected it might be AI but just because it was so specific to the game and sounded professional and it was hard to imagine contracting an actual musical artist for an adult game. The song is quality.
I also wondered if some AI art was maybe already in play. This looks find but it looks starkly different in style. I think people are more responding mid-story to that when they talk about AI. Dev was always upping the quality of the renders all the way through though.
AI is just a tool. If there is still a person deciding how and when to use it and looking at the output before publishing then there is no reason for it to be worse just because it is AI.
A lot of people are complaining about the game going too much in one direction or another. If the dev's load is lightened by using AI then it makes it possible to better flesh out a greater number of pathways. As long as the quality doesn't drop it's an all axis win.
I can get used to the art and I think the story for this update was pretty much already in the can so to speak. The next one will be better evidence of where the game is heading with incorporation of AI.
