It's 100% dependent on copyrighted material at least, even though you can't access an exact copy of it without access to the material it wouldn't exist. It's a messy issue, I have no idea how it will be solved since it's a rather new development for humanity, in the past when humans would collect knowledge from different sources to use them in a novel way there would be at least some kind of attribution, recognition of the sources, either being cited or acknowledged in a preface. With GenAI there's nothing, and probably not even a way for GenAI to tell us where it got "inspired" from to generate something.

It's going to be a very messy landscape for copyrights and intellectual property in the next years.
