It’s important in the fair use assessment to understand that the training itself is fair use, but the pirating of the books is the issue at hand here, and is what Anthropic “whoopsied” into in acquiring the training data.
Buying used copies of books, scanning them, and training on it is fine.
Rainbows End was prescient in many ways.
But nobody was ever going to that, not when there are billions in VC dollars at stake for whoever moves fastest. Everybody will simply risk the fine, which tends to not be anywhere close to enough to have a deterrent effect in the future.
That is like saying Uber would have not had any problems if they just entered into a licensing contract with taxi medallion holders. It was faster to just put unlicensed taxis on the streets and use investor money to pay fines and lobby for favorable legislation. In the same way, it was faster for Anthropic to load up their models with un-DRM'd PDFs and ePUBs from wherever instead of licensing them publisher by publisher.
