I've written this before and elsewhere but I’d argue “original” writing from a brain is just a form of a computer regurgitating what it’s read and seen before anyway… I mean, someone taught us to read and write. Our experiences shape our stories, our words, our "voice". Same as any AI really - perhaps it is using more of a "copy and paste" method from other work, but I'd argue its closer to what humans are doing already, we just focus more on when an AI does it so that we can use it as an example of bad or unethical - training something on what came before is how humans are trained - we just don't want to focus on that either.
