They're missing my point because I'm not saying it is or isn't, I'm saying that it's messy and things like the required prompt may sway the judge and/or jury one way or the other. If you provide ChatGPT an entire copyrighted text in the prompt and then go "ah-ha, the response violated my copyright", a judge and/or jury probably won't be very impressed with you. If instead you just ask ChatGPT "please produce chapter 1 of my latest book" and it does, then ChatGPT is not looking so great.
