Humans invented language. We didn't develop our mental models from it. Like other animals with sufficiently advanced brains and sensory interfaces to the world, we had mental models, and then developed a means of mapping those first to vocalizations and then to drawn symbols, allowing us to communicate and record our mental models of the world, but the models themselves and the ability to think and reason predates the existence of language. GPT-3 doesn't even have a mental model of the world. It only has a model of language. Language is the only thing it knows exists. That sure seems like a pretty fundamental and categorical difference.
