AI Companies destroying rare books to train their AIs

[Rafal]

For me the problem is not that they are destroying books.

First they destroy books that they bought and paid for. It is their right to do whatever with them.
Then, they are not destroying rare manuscripts but single copies of modern books that were printed in large quantities.

Personally I don't treat books, unlike some people, as something holy. You don't commit a mortal sin if you destroy or trash a book.

The problem is that they train AI with these books without paying a single penny to their authors. Here things became immoral.
