More than once, I've had a conversation roughly similar to the following:
Me: "I want to live forever, of course; but even if I don't, I'd still like for some sort of sapience to keep on living."
Someone else: "Yeah, so? You'll be dead, so how/why should you care?"
I've tried describing how it's the me-of-the-present who's caring about which sort of future comes to pass, but I haven't been able to do so in a way that doesn't fall flat. Might you have any thoughts on how to better frame this idea?
The original debate appeared to be limited to "Live forever" or "Dead forever" and if this was intentional, and we are intentionally ignoring the possibility of death not being permanent because that would be fighting the hypothetical, then the point below is irrelevant.
However, if we should consider the possibility that after a death a person might have a chance of being resurrected by a future sapient, then at that point, keeping future sapients alive might have potential value to that person, even if they didn't care about things that happened when they were dead.
Edit: The second paragraph was originally written in the first person, but it sounded off when I reread it, so I changed the grammar and added slightly more detail.
