There is no such thing as a truly unique idea. Everything is a result of combining concepts and experiences in different and novel ways.

AI doesn't freely use anything in a reproduction type of format. It can't regenerate a copy of a work It is no different that human awareness of a subject. Restricting this type of awareness is the same as the thought policing nonsense of humanity's past eras of stupidity. No court will ever restrict this type of information and access. If they did I could sue someone for their thoughts. This is draconian nonsense.
