Language models currently are mutated in the direction of exactly producing the desired output data, but gradually enough that they generalize across inputs in a way that appears understanding. It is more similar to compression, though, at least before a randomizing sampling strategy is applied during decode.

Anyway, circling back to my original topic: no organic being has the capability to integrate all the data arriving from their senses! They typically get more and more selective with experience, picking out only the pieces of information that are still important. Some are more selective than they're supposed to be, by choice or not (such as with dissociative disorders). In any case, the raw quantity of data coming through the senses becomes almost entirely irrelevant.
