GenAI broke copyright law, and I don't mean just infringing the rights, but disrupting the core foundations that copyright laws were built on.
Copyright enforcement assumes ability to identify whose work has been copied, but models can untraceably mashup everyone's works.
This completely messes up what a derived work is, identifying whose work has been infringed, what is fair use and remixing. Forcing old definitions to fit this either makes copyright meaningless or a maximalist dystopia.
