Ironically, it seems that some of the more "anti-AI" people I know are more likely to re-share AI-generated content without realising it, because they aren't keeping up with what today's AI output looks like.

Nah. seems people forget social media has been fake for way longer than AI. sometimes Photoshop, or editing. Sometimes just deliberately miss-attributing a real photo for clicks. heck there's a whole "fake Asian videos" subreddit, funny videos that in another light are brilliant sketch comedy but always portray themselves as real. not to mention humans consume boatloads of knowingly-fake things -- movies, tv shows, cartoons, artwork etc.

oddly enough the rise of AI may flip one of the most annoying things in social media, all the fake stuff that people think is real. a small subset of people (like myself) are less annoyed by the fake content and more annoyed by the people falling for it. Like those "Fake Asian Videos" I've seen a few that were well written, well acted and even well filmed. If it were a comedy show on Netflix it would be hilarious, the distaste I have for them is that they portend to be real and people often believe them to be real.

In the short term this is going to be way worse as even discriminating people can't tell if something is fake, but the light at the end of the tunnel is when it hits such saturation that anything real is in the minority and everyone assumes that everything is fake and keeps on consuming.
