In the human brain, language is the window to our inner simulation. Language is the interface to our mental world. And language is built on the foundation of our ability to model and reason about the minds of others--to infer what they mean and figure out exactly which words will produce the desired simulation in their mind.

…without incorporating an inner model of the external world or a model of other minds--without the breakthroughs of simulating and mentalizing—these LLMs will fail to capture something essential about human intelligence. And the more rapid the adoption of LLMS—the more decisions we offload to them—the more important these subtle differences will
