Language models aren't world models for the same reason languages aren't world models.
Symbols, by definition, only represent a thing. They are not the same as the thing. The map is not the territory, the description is not the described, you can't get wet in the word "water".
They only have meaning to sentient beings, and that meaning is heavily subjective and contextual.
But there appear to be some who think that we can grasp truth through mechanical symbol manipulation. Perhaps we just need to add a few million more symbols, they think.
If we accept the incompleteness theorem, then there are true propositions that even a super-intelligent AGI would not be able to express, because all it can do is output a series of placeholders. Not to mention the obvious fallacy of knowing super-intelligence when we see it. Can you write a test suite for it?
