That's what I thought from my various readings about LLM systems. I'm guessing that the kerfuffle from the New York Times and other shortsighted organizations is that copyright allows them to control how their content is used. With humans, it's simple as its read and misremembered. Using it for LLM training requires a different model. It probably should be a RAND fee system based on volume of training data because, as you say, the training data is converted into an abstract form.
