Part 1:
Quantum immortality seems like a great big helping of BS to me.
If you are conscious in multiple realities, and the Immortality theory is true, why are you only experiencing one reality during your life, but magically jump to a different one after your death?
One could, of course, make the argument that we are continuously shifting back and forth between different realities without realizing it, but I find this doubtful for a variety of reasons.
For one, we only jump into universes that are continuous with our past. By this I mean that I can't (as far as I can tell) walk down the street and suddenly jump into a universe where I'm a millionaire in the middle of a meeting. This means that access to universes would be restricted in some way, so the “jumping to all realities to avoid death” part of the theory would be either impossible, or require additional assumptions about the meta-universal algorithm. Furthermore, how could the universe “know” what random quantum states are needed for a continuous reality with continuous consciousness switching? No mechanisms have been proposed, and no evidence has emerged. Moreover, the particles making up your brain in a reality where you die disperse into the environment as nutrients for trees, ants, etc. We die and, according to quantum immortality, shift our consciousness to another universe where we do not die. But are the particles making our mind not still present in the universe where we are dead? If we were to shift consciousness in that scenario, we would make a “reality leap” breaking continuity.
“But wait,” one might say, “you are assuming that consciousness emerges from the brain, of which there is not proof! Perhaps consciousness is based on quantum states within the brain!”
