Analyze Nick Bostrom's Simulation Argument, which posits that at least one of the following propositions is true: (1) The human species will go extinct before reaching a 'post-human' stage; (2) Post-human civilizations will have no interest in running simulations of their ancestors; (3) We are almost certainly living in a simulation. Critically assess the probability of each disjunct and discuss the implications of the argument for our understanding of reality and skepticism.
