SCENARIO & DILEMMA
Super-advanced neuroengineers create a tank filled with nutrient fluid. If you plug in, electrodes simulate any life you choose: writing a legendary symphony, enjoying profound friendships, climbing Everest. The simulation is indistinguishable from reality. You will never know you are in a vat. You can plug in for the rest of your life.
