Humans are not neural networks, that's just a thesis.
Even novelists do not sit all day long in a closed room reading other people's work and then do a collage of what they've read. Otherwise no books would have been written in the first place.
Cut the AI off humans' work, let it interact with the real world and see what it produces. It will be nothing.
Once (if ever?) an AI is capable of producing an actual original work, I'm fine with other AIs stealing from the first one. Please leave humans alone.
