Representative take:
If you ask Stable Diffusion for a picture of a cat it always seems to produce images of healthy looking domestic cats. For the prompt “cat” to be unbiased Stable Diffusion would need to occasionally generate images of dead white tigers since this would also fit under the label of “cat”.
it was from a post around the time when dall-e and such were first catching social hype, I think. iirc the article was touching specifically on the output product of visual generators
if I find the article again I'll link it
