I'm trying to remember which movie it was where a man left notes to himself because he had memory loss, as I never saw that movie. That's the sort of thing where an AI could easily tell me with very little back-and-forth and be correct, because it's broadly popular information that's in the training data and just I don't remember it.
By the same token you needn't think there's a person there when that meme pops up in the output. Those things are all in the training data over and over.
