I was just pointing to the simplest answer I had, which didn't rely on a bunch of circumstantial and vague hunches. Since you take issue with that, I guess I'll rant a bit.

Fake photos have been a thing as long a photos have been. Very little has changed in that regard. The various tips and tricks to spot AI fakes will become obsolete a lot faster than the other critical thinking skills needed to decipher fact from fiction in any other medium: news articles, YouTube videos, social media, etc. This will be especially true as the tools used to make these images will evolve. One of those critical thinking skills is tracing a claim, especially a repeated claim, back to it's source. Another is looking at the timeline of the spread of the meme. These both involve gathering actual evidence and work for a variety of mediums. This is why so many lamented the death of rigorous independent journalism. Suddenly the news becomes so much more trouble to trust and to verify. AI is here just a fungus feeding off the corpse of journalism in the dense jungle of the death of critical thinking in the news consuming public.
