Our universe is most likely a computer simulation

28. It is possible that...

It is possible that recursive simulated universes would lose complexity at each step (a Godelian thing, I'd guess) and would quickly reach a set of rules where life wouldn't arise anywhere.

My (simulated) instinct is that we are in a universe where such a simulation is theoretically possible, but any universe we simulate would be much simpler than our own. (Since a perfect simulation of our own universe would be as big as our universe.)

That does not, however, answer the question. We could be a thousand rungs down the complexity ladder and still be complex enough a universe to contain simulated universes.

But yes, I suppose that the fact we can sensibly speculate about simulating a universe suggets we are probably not at the bottom of the process.

Or maybe we are. We don't know if we can simulate a universe.

I don't know that there is a limit to the layers that could be above us, though.
