That must be true. It doesn't make any sense that my reality is simulated but the reality in which my reality is being simulated cannot be a simulation.
If that is true, then the chances of me being in a simulation and that simulation itself being just one of an infinitely nested series of simulations are also equal. And this simulation can itself have infinite simulations and the simulation layer that is simulating my simulation can itself have infinite other simulations each one of which is an infinitely nested stack of simulations.
We may be so deep down in the simulation stack that each femtosecond of my time takes 10^10^10^10^10^10 quadrillion years to simulate several layers up in a universe with entirely different rules than our own.
If there is an infinite number of simulations each hosting an infinite number of simulation stacks then we aren't living in a simulation, that is just the nature of our existence-- it is reality.
