None of them "churn".
"The memory-of-a-memory thing"
That "isn't a thing".
"I don't remember the exact science"
You also have no idea what you're talking about.
"I do remember the metaphor I came up with (evidence in my favor!)"
I have no words.
"Remembering something is like pulling a note out of a cabinet."
Not really, no.
"lossy"
Please just stop.
"copying"
Memory is a "copying process"?
Please guys... please just stop.
> None of them "churn".
By churn I mean "lose and hopefully be replaced". That definitely happens. Some brain cells die and are replaced, some live your whole life (or die first)[0].
The cabinet is just a simile for cued recall[1]. More recently learned/recalled items are remembered better (front of the cabinet)[2]. Recalling memories in a different context can change them[3], suggesting recall isn't a "read only" operation.
