For one, a brain can’t do anything without irreversibly changing itself in the process; our reasoning is not a pure function.

For a person to truly understand something they will have a well-refined (as defined by usefulness and correctness), malleable internal model of a system that can be tested against reality, and they must be aware of the limits of the knowledge this model can provide.

Alone, our language-oriented mental circuits are a thin, faulty conduit to our mental capacities; we make sense of words as they relate to mutable mental models, and not simply in latent concept-space. These models can exist in dedicated but still mutable circuitry such as the cerebellum, or they can exist as webs of association between sense-objects (which can be of the physical senses or of concepts, sense-objects produced by conscious thought).

So if we are pattern-matching, it is not simply of words, or of their meanings in relation to the whole text, or even of their meanings relative to all language ever produced. We translate words into problems, and match problems to models, and then we evaluate these internal models to produce perhaps competing solutions, and then we are challenged with verbalizing these solutions. If we were only reasoning in latent-space, there would be no significant difficulty in this last task.
