"We think it's mostly just data found on the internet, but you're welcome to look for any breaches of copyright law" --OpenAI as they hand over the first box of printouts.

It raises an interesting point, if I train a chatbot (generative AI) on a bit of copyrighted information and it recreates substantially similar content, it's a legal problem. If a human reads the same information and tells another person verbatim it's just a conversation. Perhaps it's a quality thing, I paint the Mona Lisa badly no one cares, but if I paint it too well at some point it becomes a forgery.
