How do you know? I would bet most people can't tell what's been AI-generated from what hasn't. That's how the AI debacle of The Atlantic got started.
For example, here's what John Naughton had to say about it in The Guardian:
> what really caught my eye was the striking illustration that headed the piece. It showed a cartoonish image of a dishevelled Jones in some kind of cavern surrounded by papers, banknotes, prescriptions and other kinds of documents. Rather good, I thought, and then inspected the caption to see who the artist was. The answer: “AI art by Midjourney”

John Naughton's bio says he's "professor of the public understanding of technology at the Open University". And he at first couldn't tell the image of Alex Jones illustrating the article was from MidJourney.
