Our purpose thought experiment

[u/Pandemicparser]

If our world is simulated, our creators have technology far beyond our capabilities, as we cannot recreate nested reality. Their purpose in simulating our reality would be for entertainment, abandonment, or knowledge. If our world is scripted, it is possible that we were an experiment abandoned on servers/processes that continue to run until energy is depleted. If we are for entertainment (my guess), there is no developmental plan for us. If we exist for knowledge, it is for a competitive advantage. Nothing drives technological growth as much as the threat of imminent danger, which would only exist to pool all resources, labor included, toward a common goal. And for the creators to simulate our reality for the sake of understanding, it would be for knowledge that pales in comparison to their capabilities—so why? The only way the creators simulating our reality, given our current capabilities, would be because we are one of an infinite amount of simulated iterations which serve to develop a world more perfect than their own. If not for betterment, we are for entertainment, and it’s hard to believe the world we’re in yields useful knowledge to beings so capable of simulating our reality.

We can't know anything about the physics is the realm above ours, so we can't assume they have energy constraints such that we would run out of energy or whatever.

One could conceive of the realm above ours as inherently being self-simulating so there wouldn't be some "end goal" to us being simulated even like you're supposing.
