The AI talks about the movies like they are familiar with Singer's work. But if they were... they would known he was up-and-coming in the 90s, a decade too late to have helmed a blockbuster whose flop would have killed his career? They would have known that Singer made superhero movies _before_ Nolan not just after like the conversation suggests?
Even bringing up Superman IV is weird; it was such a dud it never gets shown, so unless they old enough to see it at the time -like me- (so would notice the 20 year gap!) or were an avid fan (so would know more about the movies!) it wouldn't come up.
On the other hand, for machines all things are equally obscure, they all happened yesterday, and are relevant if cosine similarity says they are.
