So you are not only stating than a LLM can replace a book. Directly you are saying that it is an axiom.
It is so self evident true that you don't even need to reason about it.
That LLMs can replace a book is a fundamental truth of the universe like the euclid postulates or like 1=1.
Well then there is no way to continue the conversation, because by definition axioms can't be false.
I'm happy to be convinced otherwise, but you'll have to make a concrete argument rather than just critiquing the way I'm discussing this.
