There is rock stability and no oscillation whatsoever; Indeterminacy is always with us, in the real world thanks to deterministic chaos, in physics thanks to Heisenberg and even in pure mathematics thanks to Godel and Turing, but your complications do not add any more because no matter how convoluted you make them as long as you make clear who "I" and "you" and "he" is your additional probabilities always boil down to 0% or 100%. And if you don't make it clear then everything is meaningless.

I agree with your criticism of Bruno's use of pronouns,

If you can help me to understand John Clark's critics on the use of pronouns. He is the one who mocks the many distinctions I do introduce, like notably the first person and the third person.

He fails to understand that the protocol verification bears on the personal account of the duplicated people. The question bears on the future personla experience, so comp eliminates all answers like "I will see all movies", because none of the copies will say "I have seen all movies". Almost all people will confirm that at the middle of the movie they cannot predict the next image, except by vague description like "random pattern".

Clark is inconsistent because he acknowledges the existence of the 1- I, and at the same time, he asserts that the probability question, asked to the guy before the multiplication is done, is non sense, because "you are duplicated", and here that "you" is ambiguous.

He forget that the 1-I will just be the one asked to verify the prediction.

It is obvious, in the WM duplication, with the simple definition of 1- I given, that if the guy said "I don't know, I would say either in W or in M", both copies will confirm it. If he predict W, one copy will confirm it, and one copy will refute it (and that's enough, given that Clark already agree they both have the same right of being "John Clark). If he predicts that he will be in both W and M, again, that's ambiguous. But the verification gives the meaning of the "1-I", because if the guy in W says "I am both in W and M", we will tell him: "--come on, you were asked on which city you will feel to be in now, and now you are not feeling to be in the two cities, you can't even be sure the reconstitution is already completed in the other city". And the guy in Washington should answer, "Ah, that's the 1-view? OK, I could not have predicted feeling the one in W".

but I don't think it's essential to his argument.

Hmm... You will have a problem for dismantling the quanta from the qualia. Given the indexical character of basically the whole physicalness, I am not sure it makes sense to forget the pronouns, except at the block-mindscape ontology, where indeed the addictive- multiplicative structure of the non negative integers is already enough. But without pronouns, I am not sure that there is still a "real"moon or a a "real" quark, if comp is true.

Here's a free neutron, n. What is the probability that you will observe it to decay in the next 10min? This is a very standard form of question about probability and the answer is 1/2. Bruno (and Everett) want to replace it with, "Ten minutes from now there will be two JCs one of which has observed the decay of n and one of which has not and they have equal measure in the Hilbert space of the universe."

OK. (if we abstract that I claim that once we assume comp the Hilbert space of the universe has to be shown equivalent with
the tiny (sigma_1) arithmetic seen from inside.

You don't need any pronouns to express it.

You need them to justify the working of them in your everyday subjective life, and relate that subjective life with the life of other people. In AUDA, each hypostasis can be seen as a mathematical definition of "pronoun" notions. G1 is the 3-I, S4Grz1 is the 1-I, Z1(*) is a plural 3-I, X1* is the first person plural, etc. In all circumstances we have a subject who try to predict his most probable subjective experiences. With comp, or its everything-like weakening, betting in a reality is not enough, we have to derived stability by a statistics on realities. Everett applies QM to the physicists, and I apply arithmetic to the arithmeticians, simply. Gôdel, Löb and Solovay did the hard work.
