I guess I view it a little like my experience will end no matter what. After that (can’t know for sure though) I will cease to exist.

It’s a little pointless to be anxious and not accepting of it because at the end of it, it’s not your decision when your number gets called or whether this tech gets developed before your death.

It comes today or in 1 million years, you have equal control in both circumstances. I think it’s okay to want to be around for it but I also think you should be accepting that’s there’s a good chance we won’t. To not accept that means you’re unduly troubling your real current life.

One way of thinking that might help is knowing that it is a very real possibility that death is an unavoidable part of this universe.

Heat death might just be a slowly approaching doom for all free energy including any singularity. Would that make your time here any less meaningful? Same goes for dying before any life prolonging tech gets created.
