I agree that an AI could be tricked into believing it's environment is the real world when it's only a simulation, just as we could be AIs in a simulation. But this doesn't preclude the possibility of an AI being able to completely inspect/understand the hardware it's running on in the real world, if given the fact that it actually is running on hardware in the real world.
