Yeah, perhaps writing about "you in other branches" was misleading. Let me try to clarify: a branch does not start with the point of departure, in every Bn there's also the entire B before that point. So you basically exist in every branch, only that in some branch you stop existing sooner.
'Not caring about other you' means in this case that I see no difference between the quantum russian roulette and a purely classical one: would you play a classical russian roulette with half the bullets, for a megadollar? I certainly wouldn't, so there's no reason I would play the quantum one.
I also see no important difference between classical and quantum Russian roulette, but I still don't think I understand how what you're saying about branches relates to that.
In any case, unless I've misunderstood Viliam's original comment, it seems like you and he are in agreement; his argument is meant as an anti-QI intuition pump and is really only directed at those who (unlike you, unless I'm confused) endorse QI.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
