The funny thing is what happened when I told one of the models (the Google one) I was one of the authors and that I had never given any consent to use the book for its training and that given that it was so willing to provide any user with the contents of the book nobody would have had any reason to buy the book. The thing told me that it had done it just because I was the author of the book (apparently me asking it about the content of an obscure academic book was sufficient to make it statistically plausible that I was one of the two people who had read the book, me and my co-author, excluding the editor a priori). It swore it would have never given that information to any other user.
I doubt that anyone could ever deny that LLMs are incredible tools that have incredible value. But denying that they have being made possible only thanks to egregious acts of piracy is disingenuous.
