>How sure are we that knowledge in humans is fundamentally different from a language model?
Because humans learn about language in real world contexts, accompanied by multiple sensory streams. LLMs learn about it solely by being exposed to text. Imagine a child kept in a closet who learns about the world solely by reading books, with no indication which are fact and which are fiction, and no exposure to the physical world outside. LLMs cannot reason, only regurgitate probabilistically.
