How could that be possible? After iterating 10 times the duplication, each 1p person is unique, with its definite history in the diary (like 1000110110). > therefore it is nonsensical to ask what one and ony one thing will "you" see > or feel.

They can each tell who they are among the 2^10. They have become different, but they are all the original.

That's why the entire > diary business is so dumb. Of course the diary can be duplicated. That is the whole point, but it contains different strings of 0 and 1, which specifies for each resulting person who they have become. > > > I remind you that your argument that in the two situations the > doppelgängers have different chance to meet, is not relevant, or just add in > the thought experience that someone has build a an unbridgeable wall between > Washington and Moscow. > > If the laws of physics work the way we think they do then I can never meet > my Everett style doppelganger even in principle, but I can if my doppelganger > was made in a 1p-you duplicating machine as it was in your thought experiment. If QM is slightly not linear, as shown by Weinberg and Plaga (cf this list), the doppelgänger are accessible, but that does not change the probabilities. Anyway, the meeting has no relevance for the immediate probabilities at all. > A thing like a unbridgeable wall between Washington and Moscow is tantamount > to postulating a new law of physics, That makes no sense, as your use of “tantamount” illustrates. > and there is no evidence such a law exists or any reason to even suspect that > it does in order to explain experimental results. But it is enough we could build it. Or you introduce non Turing emulable element in the mind implicitly, and we can no more say “yes” to the doctor, at least through Mechanism. You need Mechanism + some non Turing emulable magic. > So in summary if physics were different then you could be right, but it > isn't and you're not. Like anticipated, you avoid the reasoning without saying anything relevant. Why does people do that. I met a lot of people like you on Facebook, but always on the subject of drugs, or on Israel, or similar, but almost never on scientific matter. If someone else can defend your point, let him/her speak.
