Downvoters don’t know what “fair use” means. Or do, but would rather work backwards from kneejerk opposition to an outcome.

A robot read every book in the library. That’s what libraries are for. If it can’t reproduce any book more closely than a Wikipedia summary, and serves a different purpose - that’s a protected work.

Training is transformative use.

A gigabyte of linear algebra that can rap about the Silmarillion is plainly not just copying. It’s not even large enough to contain a meaningful fragment of every book that shaped it.

Protecting fair use is more important than any hate-boner toward chatbots.
