Explain Nick Bostrom's trilemma regarding the Simulation Hypothesis: 1. Civilizations go extinct before reaching post-human stage. 2. Post-human civilizations have no interest in simulating ancestors. 3. We are almost certainly living in a simulation. Discuss the statistical probability assigned to each proposition. Evaluate the theoretical implications if proposition 3 is true—does it change how we view meaning, morality, or reality itself?
