The Simulation Argument
This paper argues that at least one of the following propositions is true:(1) the human species is very likely to go extinct before reaching a “posthuman” stage;
(2) any posthuman civilization is extremely unlikely to run a significant number of simulations of their evolutionary history (or variations thereof);
(3) we are almost certainly living in a computer simulation. It follows that the belief that there is a significant chance that we will one day become posthumans who run ancestor-simulations is false, unless we are currently living in a simulation. A number of other consequences of this result are also discussed.
He leaves no room for a civilization that will one day be able to run high-fidelity simulations but have not yet advanced enough to run such simulations. We could be in base reality but one day have the capability to run high-fidelity ancestor simulations. This is the flaw in his argument.
