It is because an event can be random or probabilistic that we have to
put a measure on it (like a distribution of probabilities, or of
credibilities).

Example: the perfect throwing of the perfect coin gives an random
experience with a probability "measure" HEAD = 1/2, TAIL = 1/2.

I will ask you questions, if you don't mind. I prefer to ask question
and illustrate the use of the word in place of teaching you the
probability theory.

- Do you agree that if you throw a coin, you have a probability of 1/2
to get HEAD?
- Do you agree that if you throw a dice, you have a probability of 1/6
to get "six"?
- Do you agree that if you play lottery, you will win the biggest
price with a probability like 1/<big number>

In most discrete case, we can infer equivalence of the elementary
events on the base of symmetry (like in the old Pascal probability
calculus).

Fair enough. In all situation which will interest us: it means "random
for the subject who performs the (first person) experience".
You are the one throwing the dice? Then it will be random for you
(despite it will be random for your friend too, but perhaps not for
God).

I could agree, although it is not necessary to dig on such detailed
analysis, imo.

I am not sure I understand. There is just one comp bet: the "yes
doctor", which we can be paraphrased in step 1by "I survive (or I go
to Mars) with probability 1". (and idem in step 2)
But in step 3, ASSUMING comp, it is hard for me to see any difference
with the throwing of a coin, *for the subject of the experience*.

Suppose I propose the following two type of experiences/experiments.
The ROOM ZERO and the ROOM ONE are NOT distinguishable from inside
(but are of course distinguishable from outside). In particular, to
make things 100% clear later, i add in both room a close box with a
bottle of whisky inside. And you know this fact about the rooms.

Type 1 experience: I make you asleep, then I throw a coin, if the
outcome is HEAD I put you in the ROOM ZERO, if I get TAIL, I put you
in the ROOM ONE. In the room, I wake you up, and I ask you to evaluate
the chance of finding whisky in the box, and then the chance
(probability) of being in room ZERO.

Type 2 experience: I make you asleep, then I scan you and annihilate
you, and I reconstitute you in both rooms ZERO and ONE. I wake you up
in both room. In both rooms, you have to evaluate the chance
(probability) of being in room ZERO or ONE, and the chance of
finding whisky in the box.

 From the first person points of view, sequences of such experience
will seem equivalent, except for the "Harry Potter" or "white rabbit"
youS, which will believe in special computable sequences. OK?

Now the question can be asked BEFORE you undergo the experience. You
can predict you will have whisky with probability 1. So you can
predict that you will NOT know in which room you are with probability
one. So you can predict with certainty that you *will be* uncertain of
which room you are. So you are now not knowing in which room you will
be. So the 1/2 can be lifted in your past. You could not have known!
(This I sum up by the drawing: Y = II, bifurcation of "futures"
differentiates the "pasts")

No, please, you should'nt. Hope the explanation above has clarified.
Take your time, ask any question.

I follow Einstein. Like the Everettian. Everett provide an
interpretation of QM where reality is fundamentally deterministic,
yet, shows that the deterministic main equation of QM, SWE, explains
why observers, from their point of view, met indeterminacies, and how
they can put measure on them and do the usual quantum probability
calculus. In a nutshell: the observation of a quantum superposition is
seen as a self-duplication experience, or a differentiation of a
history.

 From what Einstein said in the EPR paper, and from the extreme
confirmation of QM which has continued, I would think that Einstein
would have adopted Everett, and then eventually comp. It is the same
philosophy. Einstein missed comp by its "conventionalist math"
blindness perhaps, togethet with the fact that he was not interested
in computer science.




> Maybe dwell a little on this


OK. Tell me if you get the point of above. Throwing a coin, and self-
duplication are identical first person experiences.
You have to really do the thought experiences.
If I duplicate you in room 1 and 2, with repetition (iteratively), you
could predict that you will be the one with the diary 111111111...,
But all your doppelganger (the 1011100010..., the 0000000...) will
know they were wrong. The "111111111..." *is* the first person white
rabbit experience, that we should not, in this protocol, take into
account.

Hmmm... It is just a teleportation without annihilation of the
original. I scan you on earth, and then I send the info on Mars where
you are reconstituted. the question is what is the probability that
you will find yourself on Mars, what is the probability you stay on
Earth. from you first person point of view you will not live both. OK?
It is really a duplication, with a zero delay on one of its branch.

Well, yes, you should already in step 3 ! In all duplication you can
meet your doppelganger. It is the main relationship between the
prestige and comp: self-duplication. It is the key basic construction
of the UDA and AUDA. I got all this by looking at amoeba, paramecium,
Euglena, and even Bacteria. I am inspired by "real" biology at the
start. I have discovered computer science in the jacob and Monod paper
on the Operon Lactose (a genetic sugar regulation system in the
bacteria Escherichia Coli). My first models of self-replication where
carbon based until i discover Gödel's proof which makes me suspect
that carbon has nothing to do with the key life principles.

So I will not try to interpret this :)

Tell me if you agree that self-duplication entails, from the first
point of view of the person(s) a feeling of uncertainty on their first
person future, and, when knowing the protocol, some means to evaluate
their chance. I can use other thought experiences, like with the movie
which I can explain in more details (perhaps the number
2^(16180*10000)*(60*90)*24 of KIM 2.3 is not easy for you(*).

Best,

Bruno


(*) I repeat there (quote from my post to Abram and you: KIM 2.3:

  don't want to give a definition of what is a normal machine, just
that you feel the point.

Let me give you another illustration which exploits the freedom of
thought a bit more. Indeed, let me duplicate you, or better,
polyplicate you into 2^(16180*10000)*(60*90)*24.

I explain. I multiply you by 2^(16180*10000) in front of a
(16180*10000) pixels screen, with each possible images (black and
white) on it.
And I reiterate every 1/24 of a second that multiplication, and this
during 90 minutes, that is 90*60 seconds.

What do you predict you will feel, as personal, subjective, first
person experience. What do you think is more probable, among:

I will feel seeing a white screen
I will feel seeing a black screen
I will feel seeing a movie
I will feel seeing a good movie
I will feel seeing "2001 Space Odyssey"
I will feel seeing "2001 Space Odyssey" with the subtitle of Caligula
I will feel seeing a random-noise-movie (what you see on TV when there
is no emission).

Of course there is a sense to say: I will see all possible movies, but
this means you are talking about yourself at the third person point of
view, and here what is asked, is what do you expect to experience or
live in your future if you are invited to practice it. By MEC, you
survive, and any of your first person experience is unique, on which
of the above you would bet? What bet will you do if I tell you that I
will accompany you in the multiplication. And send you to hell if your
bet is wrong. What bet you will do if you want to optimize the chance
of not going to hell?

The rest of the UDA reasoning shows that "this" thought experience
happens all the time in arithmetic, but the "probabilities", which
eventually could be credibilities or other uncertainty measure, are
constrained by computer science/number theory. It extends the notion
of normality from the protocol above to the whole Universal Deployment
(which I will (re)define in KIM 3).

Exercise: define the notion of "normal first person experience" for
machine in the protocol above. With the UD protocol, things are so
much complex that I will interview the Universal Machine directly to
provide hints ...
