Something being urgent doesn't mean there's a known viable pathway to an ideal implementation. The brain has billions of neurons working in tandem, a scale we're nowhere near to replicating, last I checked. And there are signs pointing to scale of neural interactions as a key factor in intelligent capabilities.

You're looking in the wrong place if you need surety. LLMs aren't "sure" about anything, and will never be. We going in circles at this point, but if you need certitude in anything, add tools to the LLM to increase surety. For some reason you seem to be pushing for a less optimal solution to a problem that already has a decent one.
BTW seems you may be - unconsciously? - crossing a person with an LLM there.
> structural in the proper human mental process
The brain is very modularized. It has sections/lobes which specialize in core life support functions, seeing, hearing, movement, reasoning, memory, etc. That's why brain surgeons can reliably know what capabilities may be affected by their actions in a given part of the brain. And all those functions are tools in some way to something else, for example reasoning would be pretty limited without memory.
And even at a larger scope, as humans we still use tools to achieve greater surety from our mental processes. That's why we have calculators, watches, cameras, etc. And why some would type "blueberry" into a tool with proven spell checking or autocorrect capabilities and eyeball the letters for a couple seconds to confirm the number of "b"s in it. The brain as a whole is still pretty fallible with all its capacity and capabilities.
