What I implied is that we should be more vigilant with chatGPT. I don't think it is common for an article to completely invent a reference that does not exist, but it is common in chatGPT.
How did I not notice this analogy?! It is in fact true that a JPEG artifact upscaled with fabricated details is the same thing as a totally forged reference of a paper describing when to diagnose appendicitis in children. Thank you.
