ChatGPT can create new things, sure, but it does so at your directive. It doesn't do that because it wants to which gets back to the other part of my answer.

I was a little bored of the novel I have been reading so I sat down with Gemini and we collaboratively wrote a terrible novel together.
At the start I was promoting it a lot about the characters and the plot, but eventually it starting writing longer and longer chapters by itself. Characters were being killed off left right and center.
It was hilariously bad, but it was creative and it was fun.
