Detail Nick Bostrom's Trilemma in the Simulation Argument. The argument posits that at least one of the following propositions is true: (1) The human species goes extinct before reaching a 'posthuman' stage; (2) Posthuman civilizations have no interest in running simulations of their ancestors; (3) We are almost certainly living in a computer simulation. Critically evaluate the logic and probability assigned to each of these three possibilities.
