Analyze Nick Bostrom's Trilemma regarding the Simulation Hypothesis. Argue which of the three propositions is most likely true: 1) Almost all civilizations at our level of technological development go extinct before reaching a post-human stage, 2) The fraction of post-human civilizations that are interested in running ancestor-simulations is negligibly small, or 3) We are almost certainly living in a computer simulation. Support your argument with theoretical reasoning about the progression of computing power and the nature of consciousness.
