Are we an ASI thought experiment?

The signs that we are in a simulation have been discussed ad tedium (Fermi paradox, quantum indeterminacy and the observer effect, universal fine-tuning, Planck length/​time, speed of light, holographic principle, information paradox in black holes, etc.). As many people also realize, it is likely the case that we are in an ASI-generated simulation, since ASI will likely overtake humanity, and such an occurrence has likely already transpired (given the ratio of simulators to those who are simulated). If we are indeed in an ASI-generated simulation, it may be tempting to imagine any simulator using a machine that is separate from itself for simulations, since that is how humans run simulations/​games. Yet the reason we use separate machines for simulations is because our own minds are incapable of directly and internally running them. An ASI would not have this limitation. Instead, why would it not use itself? And then what would happen after the simulation/​”death”? Presumably, that which once identified as human would “wake up” and realize its true identity.
