Now, let’s take a bit more timeless perspective here. Let’s look at the universe in its entirety. According to quantum immortality, there are you-moments in the arbitrarily distant future. Yes; but most of them are extremely thin. Most of the mass of the you-moments is here, plus or minus a few decades.
Why does that matter?
Under single universe assumptions, there is no quantum immortality or torment, because low probability things generally don’t happen.
Under the single-mind multi-universe view—where there is one “real” you that switches tracks in proportion to their measure -- you are also unlikely to find yourself immortal or tormented. But it’s a form of dualism—it assumes that mind and matter operate by different rules.
Under actual multiversal assumptions, multi-mind+multi-world, everything that is unlikely but above zero measure is real, from an objective point of view. The question is what happens from a subjective POV. If its at all possible for consciousness to transfer between worlds, then the subjective probability of ending up very old in a low-measure world is actually high, because there as you age past a normal human lifespan, you run out of high-measure worlds where you are alive. The assumption that beings in low-measure worlds have a faint, zombie-like consciousness can still stave off QI and QT , but lacks independent motivation. Physics doens’t say how consciousness works.
If its at all possible for consciousness to transfer between worlds
I suppose it’s not.
Then you dont need the lengthy detour about measure.
Physics doens’t say how consciousness works.
It exists in brains, brains are made of atoms, and physics has a story or two about the atoms
And consciousness isn’t a common or hard higher level phenomenon. Again, the point of reductionism is to understand the higher level phenomena in terms of Lower level activity, not just to notice that big things are made of little things.
