I think I understand it. Asking the question "which will you be" in
the MW experiment is ambiguous because "you" is duplicated.
But that question is John Clark's invention. I never ask it. The
question asked is about your FIRST PERSON expectation about 1-your
future. It cannot be ambiguous when we assume comp. To see in
ambiguity here consists in being ambiguous about "you". But I have
explicitely introduced the 1p/3p distinction to make this non
ambiguous. Comp says that in the 3p view you will be at both place,
and that in the 1-view, you will (with probability 1) feel to be at
only one place. There is no ambiguity at all. Only uncertainty or
indeterminacy. That is the point.
One can quite reasonably say that neither the M-man or the W-man is
the H-man, the H-man has been destroyed.
The original brain is also destroyed, and if the H-man died here, the
guy who accepted an artificial brain dies too, and comp is false.
This is exactly the position taken by a professor of philosophy I
happen to know.
He should publish.
This makes the probability questions trivial: What is the
probability the M-man sees Moscow? It's 1.
But the probability is never asked to the M-man. It is always asked to
the H-man. Of course, if he dies, then the probability is 0. But then
comp is false, and this shows that comp implies the indeterminacy.
The difference between John and me is that I accepted the thought
experiment as a model of Everett's wave function splitting in order
to see where it would lead.
If the Everett indeterminacy can be explained by the comp
indeterminacy, then how could the comp indeterminacy not make sense?
You lost me, here.
Please, don't quote Clarks fake and ambiguous reformulation of step 3.
Reason from what I say, and not on what some people deforms
(apparently to avoid the question asked). never use "you". Always use
1-you or 3-you, or 3-1-you, etc.
