But what would this process be comparing Now to? The last Now? What last

its operational instructions located? Is it in the universe of this Now,
which it has slated for annihilation?

If a brain has a memory of what it believes are former moments, and that
memory is being compared to the brain's own specious Now to denote a
difference and infer "change", then that would have to be a static
comparative relationship (since the brain is embedded in a single global
Now). If brains are the only regions where there are such relations
between a (specious) present and a past (memory) in that global Now,
then these would only be subjective judgements of change, not an
objective one belonging to the vaster non-brain territory (just as
change also seemed a cognitive property in the eternalism models).

If this process instead involves a "growing past" or "growing
hyperstructure", then that resembles an eternalism model with the future
removed. I guess I need more clarification about what is happening at
the "front-end" of that expanding sequence: How is this process
conjuring new Nows and adding them to that preserved past?
