I fail to understand how comp prevents natural aging which IMO must
go on in every branch of the universe. If so, no immortality.
Why? Aging is not dying.
Then time is, or might be, an illusion, and self-identity too.
Then there might be "phase transition" or backtracking, or you can
wake up in a computer maintained by our descendants, and be someone-
else, having just relive a life of the past for historical analysis, ...
Then it might depends to what you identify with, etc.
Or you might access a state of consciousness which is out of time and
space, and understand how much we have been deluded by the physical
aspect of reality, a bit like with salvia.
You might see this as a weakness of the mechanist theory, there are
many, even incompatible, form of "immortality". Some where your ego-
illusion is maintained, for some reason, and some where you stop
making such an identification, and grasp that you are not defined by
your personal memory, but by something else, that we cannot really
conceive hereby.
Obviously, we need to solve the measure problem, to get a better map
of all those comp-immortality, with their "probabilities", and perhaps
how to change them locally.

If you subscribe to the theories of MWI/UDA, then the idea of
quantum immortality/suicide follows (an observer only perceives
universes where it continues to exist, so from its perspective it
exists forever). From this, it follows that an observer can
"program" the universe into any possible state with the following
process:
- Choose a condition for the universe (e.g. "It will start raining
at my location within 10 seconds.")
- Evaluate whether you are in a universe where the condition is true
("10 seconds have passed. Has it started raining?")
- If the condition is false, stop existing (in a human context,
suicide :/).
- If the process was followed correctly (the condition was evaluated
accurately) the observer should only exist in universes with the
chosen state
This relies on the assumption that there is a possible universe
where the condition is true, and that the condition can be
effectively evaluated.
I'm not yet sure about what to think about conditions about past
events. What happens if the chosen condition was "It started raining
less than an hour ago."? This would possibly work as expected if you
don't evaluate the condition until after you chose it (you were in a
soundproof, windowless room for the last hour, so you didn't know it
started raining until after you decided on the condition).
Any thoughts? Or relevant material I should know about? Also, let me
know if there's some huge flaw in my thinking.
A possible flaw is that, if the holographic principle is true, that
there are not nearly so many possible future states as you may
suppose. What is "possible" in QM is not the same as "logically
conceivable".
That's correct, but we assume usually "classical" quantum mechanics.
Then, even if GR digitalizes the access to futures, it seems to me
that QM will still provide the rooms for immortality (not
necessarily a good news). Then, in such reasoning, QM uses comp, and
