What's an even more interesting conclusion to me, is that if you assume an advanced technological society has pulled this all off for a first time, it would follow that eventually this capability would become commonplace. You'd assume at first blush that our simulation *must* be running is some grand institute of science, but you'd be foolish to assume so. If you accept the argument on premise, its much more likely that our simulation is running in a mass-produced plaything, or is their version of a college freshman's D+ work.
You can't even assume that they think our simulation is anything special. There's no guarantee of a body that holds the ethical duty of keeping our simulation running, no five-nines, or even proper backups. We'd never be able to observe from the inside anyways, but it also follows that, eventually, the simulation will run so fast and be such a commodity that this original society doesn't think anything more of creating and destroying simulations than we think of turning our televisions on and off.
Or what if our simulation is a virus -- they may curse us and actively seek to wipe our simulation out.
And whose to say that our creators are the origin. Maybe our existence is just an experiment into their own. Its turtles all the way down until its not.
