I think you can confidently say that brains do the following and LLMs don't:

* Continuously updates its state based on sensory data

* Retrieves/gathers information that correlates strongly with historic sensory input

* Is able to associate propositions with specific instances of historic sensory input

* Uses the above two points to verify/validate its belief in said propositions

Describing how memories "feel" may confuse the matter, I agree. But I don't think we should be quick to dismiss the argument.
