@neo Impossible to prove a negative, but I have never seen this. Do you have an example that would make your case?
(A lot of the time, just avoiding the hero image entirely is the right call, but sometimes a stock photo can help to convey a mood, so if it's gotta be stock or AI, I'd say go with stock as a rule.)
@glyph @neo I have one. James O'Malley is a british dude with a substack that I enjoy reading. He regularly (not always) uses genAI images to illustrate his posts. I have found his writing to be nuanced, entertaining and informative.
Of course, this is just one counter example. I have (like you) unfortunately seen plenty of AI-illustrated AI-written garbage, but hopefully you find James' writing somewhat interesting
