If wildly optimistic predictions of LLM proponents turn out to be correct then they will never buy a book again, they will have no reason to. And this is precisely what the copyright was designed to protect authors against.

And under those circumstances, your opinion is that copyrighted books should continue to exist, with full legal protection?

How could anyone, including the authors, possibly benefit from an obsolete paradigm like that? At that hypothetical point, your attachment to legacy copyright law would arguably hold back human progress as a whole, not just impede a few greedy corporations from training models on illegally-downloaded books.

Sure, but copyright was designed to accomplish clearly defined goals and LLMs clearly undermine those goals. The motivation and spirit of the law are extremely plainly stated, you don't need to be a legal expert to understand it.

We should absolutely have a discussion about modernizing copyright (and patent!) protections. But it has to be done through a democratic process, companies shouldn't be allowed to just ignore laws that are inconvenient to their business model.

There won't be any progress if nobody is getting paid for their work. Either copyright stands and LLMs aren't allowed to train without compensation, or they get an exemption and there will be nothing left to train on in a few years.

You say it's human progress. Many, many others would disagree.
