Just tell me if you are OK with question 1. The Helsinki guy is told that BOTH copies will have a hot drink after the reconstitutions, in both Moscow and Washington. Do you agree that the Helsinki guy (a believer in computationalism) will believe that he can expect, in Helsinki, with probability, or credibility, or plausibility ONE (resp maximal) to have some hot drink after pushing the button in Helsinki?

As I said, the H-guy can expect to drink two cups of coffee.

Once again, some amplification of the this answer is perhaps in order. I cannot answer your question with a Yes/No as you wish because the question is basically dishonest -- of the form of "Have you stopped beating your wife yet?". The question contains an implicit assumption that the differentiation takes place.


Not at all. Question 1 is neutral on this, but if you prefer I split question 1 into two different questions.

Question 1a.
The H-guy is told that the coffee is offered *in* the reconstitution boxes, and that it has the same taste. Put it differently, we ensure that the differentiation has not yet occurred. And the question 1a is the same, assuming he is a coffee addict, and that he wants drink coffee as soon as possible, should he worried, knowing the protocol telling the coffee is offered, or can he argue that he is not worried, and that if comp is true and everything go well, P("drinking coffee") = 1?

Question 1b
Same question, but now, the coffee is offered after the opening of the doors.





Since it is this differentiation that is in question, the question is disingenuous: it can only be answered as I have done above.

Oh nice! The Helsinki guy, as a coffee addict, is very please you tell him that he will drink two cups of coffee.

Now, I hope, you agree that 'drinking two cups of coffee' entails 'drinking coffee', and in this case, the Helsinki addicted guy has less reason to worry about lacking coffee. You do answer P("drinking coffee") = 1.

So, just to be clear, and a bit more general: do you agree with the Principle 1:

Principle 1: if a first person event x is guarantied to happen to *all* its immediate (transportation-like) copies, then, before the copy the person can expect x to happen with the same probability it would have if there was only one copy.

OK? (We *assume computationalism. We have agreed already that it entails P(x) = 1 if x is guarantied to be presented to the guy with the artificial brain, or to the teleported (classically) person.
