Google is planning to roll out a technology that will identify whether a photo was taken with a camera, edited by software like Photoshop, or produced by generative AI models.
So they are going to use AI to detect AI. That should not present any problems.
My point is just that they're effectively describing a discriminator. Like, yeah, it entails a lot more tough problems to be tackled than that sentence makes it seem, but it's a known and very active area of ML. Sure, there may be other metadata and contextual features to discriminate upon, but eventually those heuristics will inevitably be closed up and we'll just end up with a giant distributed, quasi-federated GAN. Which, setting aside the externalities that I'm skeptical anyone in a position of power to address is equally in an informed position of understanding, is kind of neat in a vacuum.
