Descartes essentially one-shotted the logical conclusion of any Simulation Hypothesis metaphysics. A demon might deceive you as to your senses and experiences, but could never trick you as to whether you are a thinking thing. I'd add that John Archibald Wheeler added the next-step: this is a participatory universe. You are the thing running 'the simulation' - you are not false, some emulated thing. This was the original plot of the Matrix - that it runs in the human mind, and this is why Neo / others can hack it with their thoughts - but they back-tracked as too complex and said "nah humans are batteries" which makes zero sense.
