Actually yes, but that is not relevant, as arithmetic simulate all

But in another reply you say that neither matter nor consciousness
can be emulated.
Yes. But that's the advanced stuff that the people must first grasp by
themselves.
I say it out of the reasoning, and usually in a context where the
result is admitted. Not at step 3.
From that I infer that what you mean is they cannot be finitely
emulated but only emulated as threads in the infinite UD computation.
Not even that. I say that they are the 1p experience of the machines
infinitely distributed in the UD*.
Take the Helsinki guy and its continuation in M. That simple 1p
experience cannot be really emulated, without doing the duplication
again, and in that case, you don't emulate the 1p experience, you
emulate two 1p experiences. You can emulate it only by duplicating the
people, as a random oracle is not Turing emulable.
But this implies that in the MGA argument consciousness,
But here you make a gigantic jump.
even dream consciousness, cannot be emulated by the 'inert'
computation (or any other computation)
Yes, at that part of the MGA, we realize that consciousness is not
related to any particular computation at all. So we take a
computationalist supervenience, where the whole indexicalness
determines all the points of view, and we attach consciousness to the
"abstract" states and their statistical relations with the neighbors
(and this assures the meaningfulness of the counterfactuals, so that
Maudlin's problem is solved in passing).
except as it depends on 'real' matter, matter which is not finitely
emulable.
In that case, you need the "magic role" of the inert device. But if
that was true, I am not even sure I would say "yes" to a doctor who
suggest only that I buy a new toothbrush.
I am OK to talk on step 8, but only when you assess clearly the steps
1-7 before, as you did once. If not we will mix difficulties and take
the risk to run in circle.
