I think AI in this case is doing exactly what it’s best at: Automating unbelievably boring chores on the basis of past “experiences”. In this case the boring chore was “Draw me [insert character name] just how I know him/her”.
Too many people mistakenly assume generative AI is originative or imaginative. It’s not. It certainly can seem that way because it can transform human ideas and words into a picture that has ideally never before existed and that notion is very powerful. But we have to accept that, until now, human creativity is unique to us, the humans. As far as I can tell, the authors were not trying to prove generative AI is unimaginative, they were showing just how blatant copyright infringement in the context of generative AI is happening. No more, no less.
I dunno man … assume a model trained on the complete corpus of arts leading up to the Renaissance. What kind of randomness lands you at Hieronymus Bosch? Would AI be able to come up with Gonzo Journalism or modal music?
A brief glance at the history of human ingenuity in the arts really puts generative AI in perspective.
