I just think there's a lot of people arguing "well this can't be creativity" out of some sort of anti-AI signalling sentiment, where they've become so used to disagreeing with unwarranted AI optimism that they undervalue AI progress routinely. In other words, "this can't be creativity, because we don't understand creativity" or "this can't be creativity because AI is very far from human-level" or such.
(Personally, I believe GPT-3 and CLIP are already superhuman; that is, superior to the circuitry in the brain doing the equivalent job. They only look weak because we're trying to make them do all of the job in one step, when we're comparing them to the brain's highly heterogenous self-correcting approach.)
