I recently had the realization that AI is a lot like Fight Club, which is to say it's another unreliable narrator story. The guy who directed the musical also mentioned the same thing in an interview, it was posted in the Q&A thread if you want to check it out.
Then, not only has this been talked about in multiple reviews, but Hermione mentioned that it's similar to The Who's album Qudrophenia and I've heard it compared to their other opera(s) as well.
I listened to the album Underclass Hero by Sum-41 once or twice last year and it has a huge AI feel to it.
Try not to spoil anything I guess, post some others. If you have to point out some similarities that would ruin the other movie/book/whatever, use spoiler tags.
