Ok Stathis thanks for that but what about the consciousness of the
viking living in 200 AD.  The NCDSC will require some pretty unusual
branches to accomodate his survival. I've read some of your posts
before about personal identity and much of it makes a lot of sense.
I've thought about the possibility of mind uploads , even for my
viking friend but this would require the generation of huge numbers of
variants to ensure there was one which could provide a consistent
extension for him.  Indeed it would mean every possible viking would
have to be generated from DNA possibilities alone as well as with
different memories.  It's a bit of a tall order but not implausible.
It also means that many completely NEW vikings will be generated who
never existed in the past but think they did!

To keep everything more tidy I would expect that the laws of physics
might still hold in secret a form of epr effect across timelike
intervals rather than the more usual spacelike ones.  This would
entail consciousness being able to be "tuned" to accept a state change
into the appropriate "person" in a similar way that measuring the spin
of a particle in one place "tunes the spin of a partner particle in
the well known way". There is no problem achieving contiuity if the
(appropriately complete) information about a person is kept safe over
the time interval as in Bruno's teleportation thought experiment.
However if we wanted to produce a Bostrom type ancestor simulation
then there would be a huge reduncy of consciousness generated in order
to enable consistent extensions to be available as the NCDSC would
