> Once LLMs are trained with the content of this book
I strongly believe that the "future" should be LLM+Corpus - something beyond LoRA or RAG or context, but what we need and will have will be a generally strong LLM augmented with the most proper learning from the "selected library of relevant material".
And in parallel, also the reasoner over the corpus will be implemented (something that properly studies, not just reads, and achieves the pinnacle of reflection over the corpus).
Are you saying that people should then write books for LLMs only so that you can query them to get the summarized answer and not pay for the book?
