Stephen,
To combine my responses to several of your posts...
I sort of agree with your notion of multiple realities but I would
argue these are not the fundamental reality and we must assume a
more fundamental reality with the same laws of nature, rules of
logic, and fine tuning, etc. that these all occur within. Without
that it seems to me there could be no possible communication between
your realities and that they would not even be part of the same
universe.
A theory of completely separate realities not part of a single
common reality cannot explain the fact that the laws of physics, the
laws of logic, and the fine tuning, the laws of chemistry, the
current state of the universe, are the same for all observers. There
must be a common reality that includes these facts and the observers
and their separate realities in which those observers exist for that
to be true.
My definition of reality is simple and very general and takes these
points into consideration:
Reality includes everything that exists, without exception, whatever
that may be.
Including square circles?
The multiple realities you are proposing are what I would describe
as the multiple internal mental simulations of my single reality in
which all observers must exist to be in the same universe and
communicate with each other.
Each of these observers will of course have his own separate reality
VIEW and internal MODEL of that single reality, but these must
necessarily be part of a single universe to make sense of things.
On another point you claim that "computations are intractable". That
may be true in some general human math sense but with complete
certainty the computations that compute the current state of the
universe are NOT intractable because they actually occur.
I don't understand. You seem to say that you assume only a non
physical comp reality, and then you say that everything exists.
I just can't make sense of any statements you make. I don't see a
theory. Sorry.

Dear Edgar,
I have a different definition of "reality": what which is
incontrovertible for some collection of mutually communicating
observers. I find other definition of the word to be incoherent.
Given that, let me respond.

Stephen,
I think we need to back up and explore the root of this apparent
disagreement.
If I understand you you claim there are multiple computational
realities while I claim there is only one. Is that correct?
Using the definition above, yes, but I suspect that my take on
this question is wildly at odds with yours. My claim is that if one
tries to mash all of the content of the observations of all possible
observers into a single computation one would get something that is
indistinguishable from noise, hardly a computation in the usual sense.
What is my reasoning? Consider a pair of observers, Alice and
Bob, in orbit of the Earth, they communicate via a satellite system
what has a very narrow channel. Each observes a different side of
the Earth. The content of their observations is almost mutually
exclusive.
