How the mind works.
If we think in "storage" or "representation" in the context of our minds or AI, we think it wrong, because we are trying to use the concepts form CS of memeory "cells" or "slots". There is nothing like that in a brain, of course.
The proper way of thinking is that our "memory" is "structured" instead of "stored".
This explains how each access "restructures" (re-builds) our "understanding" and that after very short time we are unable to "recall" any details of our "previous understanding".
The good metaphor form computers it that our "knowledge" has to be "periodically refreshed" the way a charge in RAM chips must be. Once we stop re-generating it, it is gone forever.
So, refreshing, re-constructing, "re-building", re-writing. And pattern-matching.
What I am trying to say is that there is no "universal encoding", like on hard-drive, there is even no permanent storage. We do not store anything "verbatim".
It is rather like this - we have seen some face a few times, There is no detailed "picture" of the face stored in our mind. When we see the same or similar face, we perform some sort of pattern-matching on key features - eyes, mouth, nose, shape and then we "knew" that we have seen it before, and then "prime" all the associations. But there is no "images form retina" stored in a "files". No hash-tags.
It is like "which structure of neurons lights up when I get this sensory input" pattern-matching. "Analog", not "digital".
