Bostrom's idea is that the simulation is run by far-future descendents of human beings that were alive in what we believe to be the current time, and that it's an ancestor simulation they run for research purposes (perhaps alternate histories), out of curiosity, or perhaps just for amusement
assuming they are future humans, they're probably still mortal, but may have discovered medical interventions that permit functional immortality, unless they get totally obliterated in an explosion or something like that
we can only guess how accessible energy and computing power would be in the distant future, however, so perhaps we're running on a shoebox-sized device that some kid has on his bedside table
perhaps every kid runs one of these simulations for fun, complete with what seems like billions of years of history in our simulated universe, though it really only started when he got the device for Christmas, and either we all have false memories of what came before, or time works very differently in the simulation that it does in real reality
and, perhaps, it's not the death of any particular person or the end of a civilization that causes a simulation to end, but simply the fact that the kid gets bored of it at some point and shuts it off until it is passed down to a younger sibling or ends up in a garage sale
