Not true.

A dice has six sides, and a dice throw will generate one number in the range
from 1 to 6, exactly in that range, not more not less. This fact is
deterministic. However, the ACTUAL number that the dice will produce is
probabilistic.

Similarly, all the possible links allowing consciousness to propagate from
one frame in the MW to another are deterministic that is, constrained by the
physical laws, and mirroring these laws, our rationality. However, the actual
frame where one particular conscious PERSPECTIVE will find itself, is
probabilistic. It's all in the eyes of the beholder. This is precisely the
essence of quantum indeterminacy.

So while the MW itself is deterministic, our perception of it is
probabilistic.

I say:

Jacques responds:
<< Either it exists or it doesn't.>>

I think the root of the difference between Jacques and the rest of us is in
our perception of the world. Jacque believes in an absolute physical world
and we believe in a relative one. Which is it? For sure I don't know.
However, let me make some analogies, and Jacques is welcome to say that this
is like <<Given A, B ...Therefore everyone will believe C. ">>

Does motion exist or is it in the eyes of the beholder? As Einstein said "in
the eyes of the observer?"

Does light require a substrate to propagate? Does consciousness require a
physical implementation? And by the way, what is the meaning of "physical
implementation?" and how is it related to our rationality?

Is the measure of the Empire State Building increased because one or one
thousand or one million people have seen it? Is the measure of a conscious
experience increased because it's played back once or replayed many times?

I already know Jacques' answer. (If A and B then C).

Why does Jacques believe in the absolute and we believe in the relative?
(This is just my guess) Maybe it's in our perception of the size of the MW.
Is it finite or infinite? Is it the same as c, the continuum. Or larger?

        This has been discussed many times on the list. You could search
the archive message bodies.
        The MWI is deterministic, so the standard idea of probability does
not apply. The effective probability of seeing X is the number of
observers who see X divided by the total number of observers.

        Enough said about that.

        Either it exists or it doesn't.

        In other words, because the causal relationships aren't there,
just like we were saying.

        If A then A. If not, not.

        What then is measure proportional to if not number of
implementations? Obviously it is not a constant as a function of
different computations, and all computations occur.
