I'm not sure I'm convinced. Why do you think (of all places) the Vatican's press office has taken up using LLMs so quickly? And why wouldn't they mention it (in an official message from the Pope, no less)?
I wouldn't be surprised because an LLM is a viable shortcut to get shit done. Why would the Pope's press office not use one? You think they are too honest, too benevolent to do that? Why?
