Right. The same can be said for AI art. If you think you can exactly reproduce stylistically of some of the more popular AI work, you would be mistaken.
Like, really. If I open ms paint and just do some low effort scrawl, I have copyright on that. Level of effort has not ever decided if something is copyrightable or not.
For derivative works, there is real effort required to de distinct from the original. Maybe that's a more interesting discussion... Is low effort use of an AI insufficient to prevent the copyright from reverting to the original authors it was trained on?
