That complaint about books and stealing personally strikes me as deeply silly even by permission culture standards. The whole point of books is to learn from them. Proper summarization already separates plagerism from original content (even if it is preferrable to provide citations). It doesn't matter how it is derived - either the end product is fair use or it is effectively unauthorized publishing from including too much source content.
We should be rejoicing at the ability to have an assistant that digests the world's libraries not worrying that someone might make a profit off of it without permission.
