There is a very strong ai-vibe, but to find proof in the pictures is hard on most of them (not the pizza one, that one looks awful).
On the other hand, I have yet to take on a client this year, and so my perspective on AI developments at the IC level is mildly idiosyncratic; I know a grain of salt is required, but not how large a one, and my own experiments reveal a radically different set of capabilities and drawbacks than the technology's manic or epistaxic boosters like to describe.
Judging by what I'm seeing lately here and elsewhere, the workaday tech industry world must be developing into a genuinely horrifying grind, and I'm glad to be out of it.
It's not. At least for images, it's very easy to tell. OpenAI watermark all their generated images with C2PA.
