Dear Bruno,
My claim is that the phrase that you used above "...we agree
that for all ...." is just another way of thinking of my
definition of reality as "That which is incontrovertible for some
collection of observers that can communicate with each other". It
is the mutual agreement between all participants, be they
electrons or amoeba or human or galactic clusters, that makes a
reality "real".
OK. That is recovered in comp by the notion of first person plural
(duplication of machine population)
Dear Bruno,
How exactly is the duplication achieved? What indexes the
differences? A Blum complexity measure?
The way the duplication are done is not relevant, as in step 7, there
is no more duplication, but more something like infinite preparation/
generation of the many identical state (identical from a first person
pov). What indexes the difference is, for example, the place in the UD
work, that is the place in UD*, where the state occur in some
computation.
With comp, there exist an infinity of number k, j and s, such that the
comp state of Stephen "here and now", is given by phi_k(j)^s (the sth
state of a the kth computations in the UD when computing phi_i(j). k
might be the codes of the descriptions in the Heisenberg picture of
the cluster of galaxies, or some higher level description of the
neuronal description of you right now, etc.
The Blum complexity can be relevant, but not for indexing the
difference. The complexity of the computation can play a role in the
measure problem (but that must be justified), but not in the presence
or not of your conscious state "in" a computation.
