Well damn... Yeah, seeing them for a couple seconds on screen I didn't notice but looking closely the probability that AI was used is high. Though there's still a bunch of stuff in those drawings that AI tends to struggle with, so it's weird, because if a human fixed those mistakes they would have certainly fixed the more obvious mistakes. Supposedly they're credited to a specific artist, so I hope they clarify the situation. Very disappointed.

Unless the artist is making these mistakes on purpose and trying to make the art look like AI since it's a show about a human pretending to be a machine. If that's what's happening it would actually be funny.
