But how do you escape from the universe where you are now, into another?
According to the scenario you describe, other universes already exist,
you don't create them by starting to simulate them. So suppose you're
Trans-Anders, stuck in a collapsing universe where a Tiplerian Omega Point
won't happen, and you simulate a few timeslices from a Dyson universe in
which Trans-Anders gets to expand boundlessly. At the end of the simulation,
you remain where you were; and your Other Self exists regardless of
whether you conduct your simulation or not.
Of the various schemes for literal immortality that I've heard of,
I'd rank the Linde scenario as the likeliest sounding, with Dyson
a close second, Tipler third, and Moravec/Egan fourth.
