Why does anyone assume that ChatGPT or other tools would NOT produce previously-copyrighted content?
I can see a naive assumption that since it is “generated” it’s original. However that assumption falls apart as soon as you replace “ChatGPT” with “junior artist”. Tell them to draw a droid from a sci-fi movie, don’t mention anything else. Don’t say anything about copyrights. Don’t tell them that they have to be original. What would you expect them to produce?
