Hang on, but- plagiarism is a copyright violation, and that passes through the human brain. When a human looks at a picture and then creates a duplicate, even from memory, we consider that a copyright violation. But when a human looks at a picture and then paints something in the style of that picture, we don't consider that a copyright violation. However we don't know how the brain does it in either case. How is this different to Stable Diffusion imitating artists?
