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.
And thank god they did. There was no perfectly legal channel to fix the taxi cartel. Now you don't even have to use Uber in many of these places because taxis had to compete - they otherwise never would have stopped pulling the "credit card reader is broken" scam, taking long routes on purpose, and started using tech that made them more accountable to these things as well as harder for them to racially profile passengers. (They would infamously pretend not to see you if they didn't want to give you service back when you had to hail them with an IRL gesture instead of an app..)
This is the business model: get more money out of customers (because no real alternative) and the drivers (because zero negotiating power). Not to mention that they actually got to that position by literally operating at a loss for over a decade (because venture money). Textbook anti-competitive practices.
However, the idea itself (that is having an app to order taxi) is spectacular. It also something a high-school kid could make in a month in his garage. The actual strength of the business model is the network effects and the anti-competitive practices, not the app or anything having to do with service quality.
For instance: Monopolies often don't actually limit supply. You only make it so customers can't choose an alternative and set prices accordingly (that is higher than they would have been if there were real alternatives). Big-tech companies do this all the time. Collusion is also not required, but only one form (today virtually unheard of or very rare) of how it may happen. For instance: big-tech companies often don't actually encroach on core parts of the business of other big-tech companies. Google, Microsoft and Apple or Uber are all totally different business with little competitive overlap. They are not doing this because of outright collusion. It's live and let live. Why compete with them when they are leaving us alone in our corner? Also: trying to compete is expensive (for them), it's risky and may hurt them in other ways. This is one of the dirty little secrets: Established companies don't (really) want to compete with other big companies. They all just want to protect what's their and keep it that way. If you don't believe me have a look at the (publicly available) emails from execs that are public record. Anti-competitive thinking through and through.
