Memory is not an archive, but an active carrying of information into the future. Well organized memory is going to be stored conditionally, with the condition indicating its expected relevance, and thrown away when it expires, such as false beliefs about possible futures.
hmmm. qualitatively speaking I can see some characteristics of LRU being analogous to short term memory in the brain. I guess what I was thinking about here was the way that long-term memory is moved into and out of "brain cache" based on conditionals that are pretty opaque.

What if the division between long term memory and working memory is different than we usually think? I noticed that after 8h anesthesia, patients may return to the moment where the anesthesia took hold without noticing the gap...
-
that's consistent with how I usually think about memory given that I understand anesthesia to sever the input channels that would lead to long term memory formation. the interesting part there is that the conscious monitoring loop resumes with its prior cache pre-warmed

I used to think that WM is like RAM. If it does not constantly get refreshed by the context, it will evaporate. LTM bakes the information into ROM, so you can access it later. But now I wonder if it can be all modeled as flash? But I still think there are different modes.

additionally the curious phenomenon of lingering false beliefs that stick around even after they are decided to be false by some layer of conscious awareness. i.e. why can't we just trivially choose to forget whatever we want to?
-
Because when we stored a useless memory and become aware of that, it means that we decided to use that fact for improving our prediction mechanisms. We are unaware of the memories we let go (such as our speculative expectation what could have been yesterday's dinner).
-
that's an interesting premise. I'll have to think about that some more.
