If everything is simulated, and there is infinite number of simulated realities, as simulation is only reflection of possible reality - then maybe what is simulated continues to live in reality regardless of being switched off as just infinite number of realities that exist always at the same time.

A speculative execution bug? I like the sound of that.

Another HN once theorised / joked that the speed of light was the maximum value an integer could store and planks length was the smallest floating point number.

Thanks for the laugh. How accurately could we simulate physics/a universe if we simplified some of the constant values like how the fundamental particles behave. Not a physicist or a mathematician so be gentle if it's absolute cod's wallop.

This idea is close to the idea of modal realism: all possible worlds are real to their inhabitants, in the same way that our world is real to us. No substrate required.

It's still fun to think how simulations or other types of "nesting" interacts with modal realism. E.g. maybe there is an "Occam's razor" type of effect where we should expect to find ourselves in a world with the simplest physics that allows conscious inhabitants, simply because such worlds have more "instances" within other worlds.

That's pretty similar to Tegmark's mathematical universe theory, by the way, if you hadn't heard of it.
