That depends entirely on something outside of you, namely Washington
and Moscow, it depends on the probability of Washington producing a
sense signal that Moscow does not produce, until then your
environment is the same and so are you and so there is no
differentiation (assuming quantum randomness can be ignored) and so
there is only one Bruno Marchal. When the cities start to display
their differences then things will change, especially you.
In that sense OK. But so the first person indeterminacy remains on
what I will feel if I do the experience in practice.

The environment are not changeable, and have been chosen for their
stability.
If nothing can change then photons can not change their positions,
so they can not enter your eye, so it would be equivalent to Bruno1
and Brono2 starring into two identical Black Holes, so there would
be no difference between the two Bruno brains, so there would be no
splitting of viewpoints, so there would be only one Bruno Marchal
until something changed.
OK. But this happens because my computational state in Helsinki has
been duplicated, and the changes you talk about is the experience of
self-localization. This is a rephrasing which does not suppress in any
way the fact that in Helsinki I am uncertain about the experience I
will feel next.
There is no uncertainty in W and M which interfere with this
uncertainty.

By definition It's not a environmental factor until it encounters
you, as long as that zero or one stays in that envelope it's
irrelevant, only when its opened does it become an environmental
factor.

Good.
> and so it remains unique; and if 2 things have a different first
person point of view then each one remains unique because it's
different from anything else. OK I admit that's not very profound,
but unlike most theories in philosophies tautologies do have the
virtue of being true.

And so there is nothing insightful about "first person
indeterminacy" and it can not help us understand how the world works.
That is a quick jump. Also I am not saying that the comp indeterminacy
explains the world, at this stage three it makes things more complex.
It is a consequence of comp that we can just not put under the rug. I
am not solving a problem, I am formulating it.
>> I want to be certain I understand, you seem to be saying that if
before the experiment the subject had written in his diary "I will
feel like I'm in Washington and only Washington" and had written
nothing else, and then after the experiment you had interviewed the
subject in Moscow and he said "I feel like I'm in Moscow and only
Moscow" then you would concede that your theory of first person
indeterminacy is incorrect.
>This is utterly ridiculous. First person indeterminacy indiscates
that the guy who understand the point will never write "I will feel
to be in W and in only in W", as he knows that this will be
disqualified by the guy in Moscow. The correct guy will predict "W
or M", never "W only", nor "M only".The fact that some idiotic
predict that he will win the lottery does not lake false the
probability that the he will win, which is very small.
OK, you say that diary entry would not disprove your theory, so I
repeat my request now for the third time, WHAT DIARY ENTRY WOULD
DISPROVE YOUR THEORY?
The point is mathematical. Such diary entries would be trivial, like
both diaries containing "I am in Washington".
Given it consists of statistics, it is clearer in repeating the
experience, the theory would be disproved in the majority of the
copies find an algorithm to predict their outcomes, or if the P(having
be k times in W) does not fit with the Pascal triangle. Of course it
is non sensical.
I remind you that you introduced the idea of diaries not me and if
you can not answer my question because your theory predicts everything
The theory predicts that we don't have a predicting algorithm, just
probabilities. It predicts P = 1/2. It would be refuted if the
statistics of the first person experience violated the Pascal
triangle, or the Gauss distribution. But it does not, for obvious
mathematical reason.
You reverse the charge. I am just saying there is no algorithm, but
easy probability distribution (with the current protocol). You are the
one saying the silly thing that the experience is determinist for the
1-pov, and fail to give a prediction satisfying all the copies, except
by stopping to care about their own 1-pov, and to care only on all 1-
pov seen in the 3-view, which was never asked.
then it predicts nothing and it is not science, and the world
already has enough metaphysical mush.
Don't worry. It is hard to imagine a more testable theory, given that
it generates the set of all experimental device to refutes it. AUDA is
just UDA made completely explicit in arithmetic, and the logic of the
measurable events has already been isolated (accepting the classical
theory of knowledge), so it can be tested. Thanks to QM, things fits
up to now. But this is part 2 of sane04, and we are just at the
beginning of part 1.
And the theory is computationalism. If you have a better theory, you
might mention it.
Here, you just miss the theorem that P=1/2 for the simple duplication.
Read the definition of the 1-person and of comp. It follows from it
deductively, as you seems to understand sometimes, and then apparently
not enough to move on step 4. You might try.
