I read through the article. Apparently the studio shared work-in-progress content to prove it wasn't made using AI.
I don't know if they used AI or not, but this type of thing has been happening since the inception of gen AI. Shortly after the release of Stable Diffusion 1.5, moderators of r/Art were banning people who had been around for years because their art suddenly "looked like A.I." and told they should "Get a better art style."
In the intervening time, this type of thinking has spread. Just yesterday, I was watching a YouTube video, and they used a certain background in it which they had used before to no note. This time, however, one user claimed that background was A.I. That was all it took to send the comments into a deluge of hatred and accusations.
Here, though... I ask, if work-in-progress PSDs showing the in-progress art don't meet the burden of proof to sate these accusations, what does? How long will it be until the only safe form of art to avoid these accusations is a photo of a pencil sketch with a hand-written date nearby?
