Quantum immortality is based on MWI, which is designed explicitly to match the standard “shut up and calculate” approach to QM, which means that it cannot have any measurable effects outside the standard framework, where “Everett branches” are known as “possible outcomes”. If you expect different consequences for your personal experience in the two pictures, you probably do not understand MWI.
So I can kill myself without worrying about some nasty existential horror shit, if needs be? Because that’s really all I wanted to know and LW seems like the only place that would take a query like this seriously
Does not follow. MWI is orthogonal to “some nasty existential horror shit”, it doesn’t provide evidence either for or against your worries.
I have no idea what do you worry about, but according to our current understanding in this life there is no detectable difference between a Copenhagen world and an Everett world. As to the afterlife, all bets are off—contemporary physics can’t help you there.
Trying to understand quantum physics on the basis of web comics doesn’t strike me as a useful. The lesson you should draw from that comic is that standing near a nuclear bomb when it explodes is a bad idea.
What claim?
.
I find it counterproductive to assign probability or truth value to untestables.
.
If your decisions depend on untestables, you need a better decision theory.

Blanking your comments before retracting them? To hide changing your mind after learning stuff?
No, now that I got a clear picture of this issue I will delete this account among other things. Sorry for bothering you.
I don’t think removing the content from your comments is a good way to react to changing your mind, if that is your reason.
What might these consequences be?
.
I don’t think that’s how MWI works.

Whatever happens to you after you die.
