This makes no sense. If I buy and read a book on software engineering, and then use that knowledge to start a career, do I owe the author a percentage of my lifetime earnings?
Of course not. And yet I've made money with the help of someone else's intellectual work.
Copyright is actually pretty narrowly defined for _very good reason_.
If the career you start isn't software engineering directly but instead re-teaching the information you learned from that book to millions of paying students, is the regular royalty payment for the book still fair?
You're comparing that you as an individual purchase one copy of a book to a multi-billion dollar company systematically ingesting them for profit without any compensation, let alone proportional?
> do I owe the author a percentage of my lifetime earnings?
No, but you are a human being. You have a completely different set of rights from a corporation, or a machine. For very good reason.

Didn't Anthropic buy the books?
