Given this, I am very confused by what you think is special about the esoteric possibilities you discuss with alex_zag_al above.
That is, given my understanding of your position, it seems you should reject or endorse grieving over those doomed intergalactic explorers to basically the same degree that you would either reject or endorse grieving over a boat full of tourists who drown on their way to Greece. (I’m not really sure what degree that is… what I get from your explanation is that you endorse some amount of grief, but not as much of it as people actually demonstrate.)
Does it matter at all that they’re in a spaceship etc. etc. etc.? Or does that just happen to be the example under discussion?
It matters that I’m not going to interact with them again (or with their dead bodies). For people who are still entangled with me, like tourists in Greece, I allow more grief because in principle my grief (and by TDT-like reasoning, the grief of others) may help prevent other drowning accidents in the future. But you’re right that the actual grief I experience in practice for tourists drowning in Greece is for practical purposes zero.
The example of a spaceship is esoteric; I wasn’t the one who chose it, but I responded to people discussing exotic propositions like grieving for “acausal” people like those in other quantum branches. I can’t even afford to grieve for everyone who suffers on this Earth, in my own branch − 150,000 people die daily and I haven’t got that much grief to spend even if I tried to grieve as much as possible (which I don’t want to).
