We have agreed that they are the same person.

See above.





​> ​and you are the guy, and will remain the guy, with that memory of your time in Helsinki. So no ambiguity.

​OK good that is not ambiguous and is clear as a bell, "you" are the guys who remember being John Clark the Helsinki Man, and so "you" will indeed survive. ​


Good.




​> ​How would you (that you, still in Helsinki) evaluate the probability or plausibility that you will experience, after pushing on the button:
1) opening a door of a reconstitution box?

​0%​, "you" will not open "a door", but there is a 100% chance "you" will open 2 doors.

That is logically impossible. No John Calrk will ever feel to open 2 doors and see two cities from any of the first person experience available at that moment with that protocol. "You" will open two doors only from the perspective of an outsider. That is not the first person perspective of John Clark, which is what the question was all about. The answer was 100%, as the diaries will confirmed.






2) opening a door of a reconstitution box and see one and only one city?

​0%​

No. the question are on the first person experience, and after the duplication, both confirms seeing only one city. The answer is 100%.

You continue to give the 3-1 view, when the question is asked about the 1-view, or equiavlently, what is written in the personal diary transported in the box.



3) opening the door of a reconstitution box and see two cities at once?

​100%​

Then none of JCW nor JCM needs any means (phone, mobile) to communicate, and you are pertending that duplicate brain get telepathic power, where comp + the protocole makes this false. The brain/computer reconstituted are mechanically independent.






​> ​Note that by definition of first person experience, "seeing two cities at once" means literally being a person​ [blah blah]

STOP RIGHT THERE!​ If as Bruno Marchal​ ​just said "you" means the guys who remember being John Clark the Helsinki Man then after the duplication there is not "a person" who fits that description, there are "persons" who fit that description​.​

Exactly, so we have to look at both 1-diaries, and both contains "I see only one door and one city behind"




If Bruno Marchal​ ​no longer likes that definition of "you" then change it,

I keep that definition. No problem at all, as long as you read all (or a significant sample of) the first person diaries obtained after the duplication(s).



or better yet just stop using those goddamn ambiguous personal pronouns​ and use the referent instead.​

It is as much ambiguous, if you confuse 1-views and 3-1 views, and the pronouns or the referent are both made non-ambiguous when we distinguish the 1-views and the 3-1-views.
