Yes. But if we also add quantum immortality here, we could ignore all finite branches. However, there is a logical uncertainty about the validity QI, and it has less than 50 per cent chances to be true.
Well, we can avoid the debate about quantum immortality if we specify that we’re talking about lifespan from the perspective of a 3rd party observer. After all, the OP is talking about the effect of technological progress, whereas if you accept quantum immortality then you would have accepted it even without progress.
The life expectancy is infinite, but the median is finite unless the probability of immortality is at least 50%.
