That looks nice. So now, I ask to you, and to everybody a question,

You are in Helsinki, and you are scanned and annihilate as usual,
and (3p)-duplicate in three exemplars: one is reconstituted in W
and two in Moscow. You are told before, in Helsinki, that in
Moscow, the two exemplaries are in the exact same state and
environment, and that this will last forever (they will never 1p
differentiate).
In what sense are they "two"?
Let us say that one is in a virtual environment imitating Moscow
centrum, put physically at the North of the "real" Moscow, and the
second one, is in the numerically identical virtual environment
imitating Moscow centrum, but put physically at the South of the
"real" Moscow. Again, we suppose that the substitution are done at the
right substitution level, so that the first person experience are
identical (but the processing is duplicated).
Do they have exactly the same point-of-view?
Thay have the exactly same 1p history, yes.
You say they are in the exact same state and environment. So is
the environment the same? Is it the same at the quantum level? The
same quantum interactions with cosmic rays, etc?
Yes. Exatly the same with respect to the substitution level. ...
better to make the environment virtual to add a bit of realism.
I think Leibniz's identity of indiscernibles applies. But Leibniz
didn't know about quantum mechanics and superposition of states.
Nor do we, in that reasoning. We suppose a physical reality able to
run a universal Turing machine, but not much more, for the sake of the
theoretical reasoning.
