Is this true? As far as I am aware there are zero pixel for pixel recreations by an image generating AI of any pre-exisiting images and no written work has ever been word-for-word reproduced in full. The closest I've seen are images highly similar to the Mona Lisa which is already copied virtually everywhere without AI and brief passages from commonly copied written works that veer into hallucinations after a paragraph or two.
Because the parent comment says "But we can" in response to the claim that AI can't generate "exact copies." Generating exact copies would be a lot more legally notable than outputs that are only similar or partially copied. As far as I know exact copies haven't happened and was legitimately asking for cases where it has.
