I think the problem is the lack of a verifier to check the attempt at creativity in a tight loop. Creativity could just be randomness (off the existing average) plus selection done many times over a 30 year career.
That is, you try something new (random) and you, the human, are also the verifier to see whether that random new thing was subjectively good, and then you select based on that.
In this understanding of creativity, creating a new style is a gradual process of evolution (mutation and selection) where your own brain is a necessary part of carrying out the selection. "Did the new idea (mutation) I just tried make me feel good or not (selection)?"
That activity of you being the verifier is effortless and instant, but the AI fundamentally can't tap into the verification and so it has no ability to do the selection step after randomness, and so it is impossible for creativity to emerge no matter the architecture (unless you somehow create a proxy for a human verifier which seems insanely hard).
The only solution I can see to this is to try to simulate this process, seems possible but hard.
