That's confusing. I find it hard to believe a bacteria can dream.
The
UM implemented by a bacteria could *potentially* run any program,
but
it is *actually* running the bacteria program. To suggest that
bacteria (e.g. one of the class of "all UMs") can dream by virtue
of
being definable as a UM generates more confusion than clarity.
Put another way, if a particularly instantiated UM possesses the
ability to dream (to imagine), then that says something non-trivial
about the constitution of that UM's cognitive architecture.

Hi Terren,
If a bacterium is a physical system capable of implementing a
universal
Turing machine aka the particular bacteria's program, then Bruno's
argument
shows that it will necessarily be able to dream, for what are
dreams if not
alternative TMs running on the same hardware via dovetailing?
Onward!
Stephen
Dreaming in the context of Bruno's remark means that the running of a
single program could result in alternate 1p realities being
constructed... not that multiple programs could be run in the UM. At
least, that's how I interpret it.
Dear Terren,
How does the running of a single program generate different
content (in the sense that the program is equivalent to a virtual
reality generator)
The notion of virtual reality generator is nonsensical with comp,
although it can be approximated by lowering down the substitution
level. Deutsch needs a physicalist revision of Church Thesis, which
makes no sense once we assume comp.
unless it is a dovetailing of many programs? Is this how you get a
many = one situation for programs? This makes no sense. AFAIK, 1 =
1, many = many. many =/= one. Or is my mathematical knowledge faulty?
This is unclear.
A bacteria is a universal machine in that it can potentially run any
program. However, bacteria as they appear to us run specific programs
(as selected by evolution). Their instantiation as such is a stable
measure relative to us - the shared 1p plural reality. Bacteria that
run programs capable of dreaming (as above), while possible, would
probably count as white rabbits.
Terren
Could you tell me this explanation in your own words,
particularly what "the shared 1p plural reality" is. I truly do not
comprehend this concept as you are using it here. How is 1p content
sharable by a plurality of entities?
You need to duplicate population of machine. You need to make enter
many candidate in the teleporting or duplicating devices. You can
understand that they will share their first person indeterminacy.
This is provided in QM by the tensorial structure of the quantum
state(s). In comp, that tensor structure should be retrieved from the
comp quantum logics.
AFAIK, any experiencial content that is "sharable" by a plurality is
3p,
Not at all. It looks like that, but it is first person plural. That's
why physics is really reduced to epistemology. The quanta are
particular case of qualia. The MWI confirms this, and save comp from
solipsism.
in other worlds content that we all agree on as being "real" and
having such and such properties is the definition of "objective
reality".
Only with the Aristotelian theology, which is not compatible with
comp. The physical objective reality is a sharable subjective
experience.
