> At this point what news site isn't AI written?

The New York Times, The Wall Street Journal, The Guardian, The Atlantic, NPR, BBC, The Verge, The Economist. That's just off the top of my head. Basically none of the reputable papers will touch AI.

(I guess I have to add an "as far as we know" footnote but I'd be truly shocked if the New York Times was secretly using AI.)
