Is there any proof of this? My feeling is that people just assume that since something has been generated by AI, then it must not be original. And truly original thought or craft is exceedingly rare if it exists at all: everything comes from something else. Individual innovations are often small.

This is magical thinking. Humans don't have a small device in their head capable of "true creativity" whatever that even is. At most, they experience so much random input that their outputs are less predictable. But nothing that LLMs won't be able to do soon; as for raw intelligence, they're already smarter than the large majority of the population.
