Liz,
I think Edgar's computational reality can be consistent with the
computational theory of mind if you somehow constrain reality to be
small and finite.
OK.
The moment you let the universe be very big (eternal inflation) then
you also get an infinite number of computers built by aliens in
distant galaxies, any of which might be simulating you, and the same
consequences Bruno points out apply.
OK. But the universe might need to be robust too, which, in passing, I
am not sure our local cosmos can be, even if infinite, unless there is
really infinite room at the bottom, which I doubt. The UD has toe
become unboundedly large ...
My question to Edgar is why do you believe reality is finite? This
seems to contradict a number of current scientific theories.
Also, when do you believe reality was created? And how do you
explain it's origins?
Good questions.

No Liz, I told you what it IS. It's the happening in computational

You seem to be nit picking...

I don't know why there is this concern about Edgar's computations.
It's seems very much like Bruno's, except Bruno's Universal
computer is running all possible programs (by dovetailing). The
time that appears on clocks is a computed ordering relation which
is conjugate to the conserved quantity called "energy".
Bruno's dovetailer is supposedly running (if that's the word) in an
abstract space, while Edgar's processor units are, as far as one
can tell, intended to be in some sense physical. It's clear what
Bruno's ontology is based on, he makes it explicit in his axioms.
It isn't clear what Edgar's ontology is based on - he seems to be
assuming that time and some form of computation are fundamental
properties of the universe, but not what those computers are
running on (by Turing equivalence, I assume they COULD be running
on a desktop PC in some other universe) or what his "universal
present moment" consists of - is it a linear dimensio, say? But
then it appears to be quantised, since it only supports discrete
computational steps. Can time be quantised? What are the
implications? Do things like the Landauer limit come into his theory?
The concern is, I suspect, due to...
a) a lack of rigour, either logical or mathematical, in describing
the theory
b) a lack of testable results, or indications of how one gets from
the theory to the observed reality
c) a bad attitude
