My most charitable interpretation of this is that he, like a lot of people, doesn't understand AI in the slightest. He treated it like Google, asked for some of the most negative quotes from movie critics for past Coppola films and the AI hallucinated some for him.

If true it's a great example of why AI is actually worse for information retrieval than a basic vector based search engine.

While I'm sure that some people were cool on The Godfather when it came out, it was the highest-grossing film of 1972 and won Best Picture at the 1973 Oscars. That's not exactly a good example of a movie being vindicated in retrospect.
