@pluralistic your latest collumn had me thinking. We use books to train inteligences now - it's one of their main uses and always has been. Nobody has ever suggested that, if you're going to use a book to teach people with, you need to pay for more than buying them a copy of the book.
I fully expect AI companies to raise that argument in their lawsuits: that using a book to learn is definitely not a copyrightable activity since they've always been used that way. Indeed, one of the groups of people who MOST rely on books to learn: is future authors.
Great readers make great writers after all.
As writers, we learn from other writers, by reading their books.
