That's not very clear, IMO. With ordinary raw threads or processes
running on a computer, sure, one moment the process has access to
data structures X and Y, and the next, equal access to Z. But that
entirely ignores the knotty problem of how memories are added to
people, as you say "instantly".
Normally each new experience you have is immediately compared
on some sort of salience measure to everything else that has ever
happened to you, i.e., to all your other memories. That's why you
are "reminded" of things, some of which happened a long time ago.
Now if you get enough new experiences, the new memories that
are generated are slowly integrated into all your existing ones.
The computer analogy seems a little strained here, at least with
the kinds of algorithms we have today running on our machines.

Well, I suppose so. At least keep the provisos I suggested
above in mind (thanks) and be very skeptical of every step
you take, of course, to minimize the damage done to the
original questions. But sure. After seeing Stuart Armstrong
successfully get away with modeling states of a TM (or
generations of a Life Board) with mere polynomials, and
state transitions as differentiation, I'm pretty willing to listen
Well, almost anything :-)
