That's true, regarding the brain as a classical computer or as an abstract

QM case; "freezing the wave function"?

If it takes the brain 100 ms to compute a moment of awareness, then you can

Suppose your brain paused for 1 us every 99 ms. To an external
observer you would be functioning normally; do you think you would be
a philosophical zombie? We can change the thought experiment to make
the pauses and the duration of consciousness between the pauses
arbitrarily long, effectively cutting up consciousness however we
want, even if a conscious moment is smeared out over time.
Use the quantum Zeno effect. Observe its state repetitively. You will project it again
and again in its original state. That is one method.
That requires constructing an observable that has brain states as its eigenstates. Such
an observable is a quasi-classical interaction that entangles the state with the
environment via decoherence. So whether consciousness would survive this, is already
equivalent to the question of whether you should say 'yes' to the doctor who proposes to
replace your brain with a classical computation.
Or, second method, emulate the quantum object evolution on a classical computer, and
freeze the classical computer.
Does the classical computer obey the 323 principle? I think such computers don't exist
(except in Platonia).
The UD emulates also the quantum computations.
Yes that's another formulation of the same proposition. But I wonder how it emulates the
non-interaction experiments. The conventional computation assumes true randomness.
