Where was I arguing that human output is not creative at all?

Human creativity is for the most part derivative in some way, that is the nature of it and my point. I was contrasting it to illustrate why I think the idea that machines cannot be creative is wrong. Especially given that current models will only get more complex and nuanced in the future.

I never said that humans cannot be creative because creativity is derivative at any point. We are engaging in another human pastime; tribalism.
