nobody knows how these models work. Not even experts. These are black box algorithms where people understand these things in terms the analogy of a best fit curve in a series of data points. Outside of this analogy... nobody understands how generative AI works.

What made a model for a specific situation choose to generate a hand with 6 fingers instead of 5? Or 5 instead of 6? Nobody knows.

Sure, but if you were out to use these images - maliciously or otherwise - you would just filter out the 30-50% that don’t look real.

That's well above the threshold for destroying even the pretense of photographs having any information value on the Internet.

Even before generative AI was an issue, in the US you couldn't just tell a court "this is a photo, therefore it is evidence". There had to be witnesses would could testify about how that photo was produced, and the other side could cross-examine.

But yes, you're already seeing politicians caught doing or saying embarrassing things claiming it's all a deepfake, but in most prominent cases of this there were lots of witnesses who can confirm that yes, they did say that.
