People are getting a little too paranoid if you ask me, and it's always tempting for people to jump on the bandwagon in order to make themselves feel cool or aloof or in-the-know or whatever else. I don't hang around anywhere except Lemmy so I have no idea if it's as bad as it is here, but it seems like any time basically any picture of any stripe gets posted there are always one or two dinguses who reflexively parrot "it's AI!!!!" and claim they can magically tell, even though it demonstrably isn't. For extra hilarity, this occasionally includes people howling about how literal decades old image macros that were circulating in the first couple of years of the century are "obviously" AI because apparently it's their first friggin' time using the internet or something.
For the record, I vehemently loathe AI slop and the current crop of generative "AI" products in general, I don't use any of them, and I never will. But people really can get carried away over this, too.
