I will say, I've enjoyed playing with stable diffusion, I've been impressed with the explosion of tools built around it, and the stuff people are creating ... But all the stuff about bias in data is true. It really likes to render white people, unless you really specifically tell it something else ... in which case, you may receive an exaggerated stereotype. It seems to like producing younger adults. If all stock photography tomorrow forward was replaced with stable diffusion images, even ignoring the weird bodies and messed up faces and stuff, I think it would create negative effects. And once models are naively trained on images produced by the previous generation, how much worse will it be?

I don't think "don't let the plebes have the models" is a good stance. But neither is pretending that the ethics and bias issues aren't here.
