Elon Musk almost terminated our simulation.

Simulation is a simulation only if everybody is convinced that they are living real life. Bostrom proved that we are most likely live in a simulation, but not much people know about it. Elon Musk tweeted that we live with probability 1000000 to 1 in simulation. Now everybody knows. I think that it was 1 per cent chance that our simulation will terminate after it. It has not happen this time, but there may be some other threshold after which it will be terminated, like finding more proves that we are in a simulation or creation of an AI.

It seems possible to me that after passing some threshold of metaphysics insight, beings in basement reality would come to believe that basement reality simulations have high measure.

Past a certain point, maybe original basement reality beings actually believe they are simulated. Then accurately simulated basement reality beings would mean simulating beings who think (correctly) that they are in a simulation.

I don't know how to balance such possibilities to figure out what's likely.

One idea how to measure the measure of simulations I had is that it is proportional of the energy of calculation. That is because the large computer could be "sliced" into two parallel if we could make slices in 4 dimensions. We could do such slices until we reach Plank level. So any simulation is equal to finite number of Plank simulation.

Base reality level computers will use more energy of calculations and any sub-level will use only part of this energy, so we have smaller measure for lower level simulations.

But it is just preliminary idea, as we need to coordinate it with probability of branches in MWI and also find the ways to prove it.

Interesting idea. So I guess that approach is focused on measure across universes with physics similar to ours? I wonder what fraction of simulations have physics similar to one level up. Presumably ancestor simulations would.
