That doesn't really answer anything though. There are tons of human cranks out there too who are perfectly willing to spend tons of time on their "theories." Humans make errors too. If you don't have a way to evaluate the source material or some endorsement from someone you have a reason to trust, then AI doesn't change that. If you do have an endorsement (e.g. Terence Tao says some AI book is extremely well done, or puts out his own book that he openly used AI to write), then why would you discard it because AI?
