I think this comment is uncovering a profound link between free will
and conciousness. MWI provides us with a natural solution to the free
will vs determinism conundrum. (David Deutsch gives a good discussion
of this in his FOR book). I have argued that a Turing machine
can never be concious, because it can't have free will. The output
states of the Turing machine are precisely given by the program and
the inputs. One needs at least to inject a little randomness in the
algorithm, which then offers a real choice between MWI branches for
the machine to travel down. It is this possibility of choice that
gives us our psychological sense of time, another important
characteristic of conciousness, and is also naturally related to the
arrow of time induced by the second law.

However, the perverse flip side of this situation is that an
unconcious Turing machine can implement a universe in which
conciousness exists, at least this is how I understand Bruno's
thesis. Of course the "time" in which the Turing machine executes its
program is completely unrelated to the "time" that the concious
entities implemented by the TM experience.

Thus, it would seems, conciousness is very much a relative concept,
just as free will and time would be.
