If you think you are the only real human alive, all risks are existential. If you die they shut down the simulation. This is why Musk will never fly in one of his own rockets. And my bytes thank him for it.
@Soyweiser@Amoeba_Girl Any sim-solipsist worth their processing time would know that even if one instance dies, certain calculations might be memoized and reused in other instances. If the rocket blows up, they can just reuse that sequence on another Musk sim if his rocket blows up, too. If you're important enough to be the sole protagonist, why not be important enough to have a billion instances of yourself running concurrently in variant simulations?
But are those copies really you? They are copies after all, and eventually your instance might hit a dead branch in which all the actions lead to death and the only non-dead branch of you might be so diverse in different choices it made it can no longer be considered you. That is simply not a risk I can take.
@Soyweiser As long as they are enough like me to still be better than everyone else, they pass the narcissism filter. All those billions will eventually have to fail somehow anyway, to determine the grand champion best possible me that will be copied the most for the next round.
