Radically «unlike», since the main activity of the intelligent entity is verification.
Hopefully - but that would be the absolutely critical part.
> stable data store to retrieve facts rather than trying to pull facts from the model itself
This is not clear: intelligence is a process of refinement of a world model.
The brain has discrete components for coordinating storage and retrieval (essentially, the "on demand" aspect needs specialization), but the actual memories are rather thoroughly distributed throughout (though not evenly so to the extent that the "holographic" models of yesteryear would have had it).
