a) I linked to an entire album of pictures that 99% of the population would not identify as AI, including the population that knows what AI slop is.
b) This is a gross oversimplification to the point of being unhelpful and pretty much wrong. You don't seem very familar with how these models work.
There is no inherent reason why sampling from the latent space of a model limits us to average of any concept.
Not to mention the models are learning what average means and what exceptional means and can increasingly produce both at will. As they get larger the degrees of seperation between those "sub-concepts" of each concept grow larger and larger.
The reality is humans are good at convincing themselves they're good at things. The false positive and false negative rates are already going up for AI art, and it's only going to accelerate from here on out.
