It is as you wish, but it is my way to question the humans, through UDA.
Then the number is my way to question the machine, through AUDA.
You seem to have a problem with thought experiences and with numbers,
which prevent you to follow both path.
Don't worry, because perhaps you have your own path and interest and I
know we agree on some fundamental issue.
The only thing which sometimes worries me is when it looks you are
sure that machine or number are dumb, which for me illustrates a
common human prejudice (the feeling superior ...)

It seems to me that I agree with you. Let me give you my precise
definition of a perfect throw of a dice. You know, as Brent Meeker
recall nowadays there are magician which can "cheat" on those things
in extreme brilliant ways.
So I will accept that a thrown of coin is "perfect" (relatively to the
Probability 1/2) if the coin is enclosed in a velvet box and the box
is shaken during 5 days by 500 monkeys themselves taken randomly among
100000 monkeys, and this when God is not looking (to prevent God for
being the magician accomplice, who knows ...).

Einstein was alas still a bit brainwashed by Aristotle, imo. You know
that I think that the Platonists, and especially Plotinus, has well
coped with the epistemic enrichment coming after him, and I believe,
after us .... (Lewis Carroll too I think, actually).
And I would so much be pleased to let you guess that the little Lobian
machine can cope a so big epistemic enrichment too...
Theology has to come back in Academy, I think, if only we want some
human human science ... I'm afraid that science has been interrupted
in 529.
The enlightnment period has only aggravated the gap between human
science and exact science. This could explain in part the inhuman mess
on the planet.

I admire too. Kim is courageous.
Well, for the tenacity we will see :)

My domain is theology. scientific and thus agnostic theology. I
specialized my self in Machine's theology. Or Human's theology once
assuming comp. The UDA shows (or should show) that physics is a branch
of theology, so that the AUDA makes Machine's theology experimentally
refutable.
Will machines go to paradise?
As a scientist I *know* nothing, but I can appreciate some theories.
Theories are always hypotheses, waiting to be changed or reinterpreted.

I am not sure I understand, given that "probability" is a measure of
our ignorance (from us to God, depending on the domain indeed).
In deterministic theories like comp or Everett QM (the Many-World),
all computable probabilities reflect an ignorance of a subject. With
Omniscience probabilities are 0 or 1, it seems to me. Well, it depends
at which level we look at, and through which notion of person we make
the observation, also.
