To expand on Günther's question: If we equate computational states
with mind states as COMP assumes, and if this universe is computable,
would that imply the universe itself can be considered a singular
mind?  I think this is a consistent viewpoint not contradicted by
experience.  Of course I don't know what you, or anyone else is
experiencing right now but that is only due to a lack of communication
and accessibility.  If you take a normal brain and cut the link
between hemispheres you create two separate minds, but are they not
the same mind only limited in transfer of information?  What if we
grafted nerve fibers between two individual's brains so they could
share thoughts and experiences, two minds can become one via
communication.  Since all particles in this universe are interacting,
the computational history of a mind must include the whole universe,
or at least what is in its light cone for a given extent of time.  If
this universe is one mind, then the universal dovetailer would be a
maximally conscious omega point, conscious of everything that can be
