There is no problem of induction. There is a problem of induction only
for those who believe that science can prove a fact about reality.
There are only worst, bad, good and better theories, but all theories
are hypothetical belief. from the baby theory according to which he
has parents, to the existence of moons, suns and bosons, theories are
hypothetical, and their interpretations preserve the "hypotheticalness".
A scientist never say "I know". (and this I think is the way Popper
solved the "unduction problem". But it appears only to those who want
their theory to be true ... by authority.

Sure. I will ask a bank to lend me huge amount of money, I promise
them to reimburse when I will win ten times the big lottery in a row.

Free will does not exist for those who live to work.
Free will does exist for those who work to live. If not, they are
exploited? From universal they are forced to be particular. that's how
souls falls and englue themselves, they loss their free will. Now work
no war can make you free. You are, and can remain by resistance and
vigilance.
In the normal worlds.

That is true. But no theories can predict this. Er... well, no
consistent theories can predict this. Inconsistent theories can prove
we are immortal indeed.

Come on Kelly, you know my favorite postulate assume all computational
histories (Robinson arithmetic) so I have no doubt there is a
continuum of Bruno, even densely distributed between any two points of
the M sets), all englued in their history and soon or later quite
different, as different as Kelly and Bruno in short time, as different
as Bruno and the amoeba on longer time ...
The question is just this. I want coffee. How is it that I can realize
the dream "drinking of cup of coffee". I am good willing. I have try
your theory this morning. At first it works. It was a real and big
pleasure to await for the white rabbit bringing my cup of coffee in my
bed, where I could stay longer. But after two hours i was a bit
missing something, and I ask myself: why did I bet I would necessarily
be the Bruno in the White rabbit world instead of I seems (at least)
the usual normal (and a bit sadder) world where in most circumstances
I have to use my free will, my free time, my free action, my (not so
free) coffee and this up to the point I bring the warm product to my
mouth.

Ah! This is indeed in the "guardian angel" theory of the machine M, on
the machine M.
But of course the machine M, if she wants to remain scientific, or
just self-referentially correct, should say instead:
If God exists, then God helps those (universal machines) which help
themselves.
Plato's "truth" helps in the limit That why god is good, in Plato.

I tell you. I will not try the white rabbit method of realizing the
experience of drinking coffee no more, in the morning.
OK, I admit I do it everyday implictly in the evening, it is perfect
how the white rabbit seems to understand I don't want a cup of coffee,
he never bring me coffee at that time. Is that an evidence that I am
in a world with white rabbits?

? I don't rule out the whole structure of possibilities, and I defend
the idea that actuality is possibility from inside. I include type of
relative or conditionnal possibilities. Indeed I explain that once you
assume comp, you have to take into account the interference of
histories due to your personal finite level of distinguishability
among a continuum of histories.
Mathematics illustrates that immaterial beings, like numbers and
digital machines, obeys laws. Of course you can contemplate the
picture, not trying to use it. I like very much poetry and many arts.
Actually to use the comp physics to measure the mass of the Higgs
(Brout Englert) Boson would be like using String Theory to prepare a
pizza, but comp gives a global coherent picture, and it gives a frame
where the "laws of physics" can emerge from.
Nobody can be sure it is true, but once you say yes to the doctor,
then if your survive, you are under its play.
