The idea that an LLM can replace the role of a book doesn't seem like it should even be controversial to me.

You buy a non-fiction book to learn something, or to act as a reference.

An LLM provides an alternative mechanism for learning that thing, or looking up those reference points.

What am I missing here?

Do you think a search engine could replace a book?

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.
