It’s not the “incorporating it into their understanding of the world” step that is the problem, it’s the casual plagiarism that follows which is upsetting artists. If some genius human were capable of ingesting every piece of art on the planet and replicating it from memory then artists would sue that person for selling casually plagiarized works to all-comers. When people get caught plagiarizing works in their university essays they get severely punished.
