Yes, a lot of creativity is fuelled by inspiration. One can't create much in a bubble. However: I could draw a rkbvrpoi, and my human intuition enables me to consider what such a thing might look like. I can make it up and make something feasible of it. I can give it a history, I can place it in culture (or maybe it is itself a culture), and I can do whatever I want. Yes, that requires some level of inspiration, and drawing from what I've observed and experienced would make the rkbvrpoi a lot more believable - if that's my goal.

A so-called AI can't do any of that, and even if it could, it would be meaningless and soulless.
