Aren't the AI companies just buying one copy of each book?

And this is supposed to be concerning?

The blog post is about rare books. Meaning, AI companies scanning and destroying rare books.

Yes, read more carefully: one copy. Do you panic when the "wrong person" buys a single rare book?

The issue is that the copyright holders and book publishers make it hard to make more copies, not that somebody bought a single copy of a book, no matter how rare.

If you could print any book on demand (paying for it), the issue would vanish instantly. And who makes that decision?
