If I draw a perfect clone of Donald Duck in the privacy of my home after looking at hundreds of Donald Duck images online, there is nothing wrong with that
In your picture example it would be an exact copy…
But even if you started a business and when people asked for a picture of Donald Duck, giving them a traced copy is still copyright infringement… Hell, even your bad analogy of a person’s own drawing, still copyright infringement
The worst thing about these chatbots is the people who think it’s amazing don’t understand what it’s doing. If you understood it, it wouldn’t be impressive.
