AI safety expert Dr. Roman Yampolskiy answers the question with no pause: Are we living in a simulation? Yes. We are. He says the math is ugly. If we are about to build intelligent agents, and we already build virtual worlds, then anyone can spin up civilizations full of beings like us. Every kid plays a couple games. Billions of fake worlds. One real one. What are the chances you are the original? He has believed it for five years. Bostrom’s paper got him there. Bostrom was 20, 30 percent sure. Yampolskiy thinks the number is higher. You asked if that makes you fake. He said no. If you are inside the sim, simulated rain still soaks you. You still feel pain. You still fall in love. The simulators have had 15 billion perceived years to kill us. They didn’t. They can shut it off any second. The new threat is us. Building a competing superintelligence inside their world. That may be what triggers shutdown. Lights out.
