MIT Simulation Expert on Intelligent Life, "Ancestor" Civilizations & Reincarnation | Riz Virk • 329

Guest: Riz Virk · Host: Joey Def, Julian Dorey
This conversation revisits and updates simulation theory with a computer scientist and video-game industry veteran who wrote a widely read book on the topic. The guest walks through why he has raised his estimate of how close humanity is to building a fully immersive, indistinguishable virtual reality, pointing to rapid advances in AI-generated video, voice cloning, procedural world-generation, and smart NPCs. He connects this technological trajectory to quantum mechanics puzzles like the observer effect and delayed-choice experiments, arguing they make more sense as computational optimizations than as features of a purely physical universe. A large portion of the discussion treats world religions and mystical traditions as attempts by people who had transcendent experiences to describe a non-physical reality using the technological metaphors available to them, from souls as clothing to karma as a quest-generating algorithm. The host and guest also discuss near-death experiences and life reviews, dreams, synchronicity as an 'informational layer,' and how deep immersion in roles—whether an actor, a video game character, or an online persona—can blur the line between performance and identity, with examples ranging from Grand Theft Auto to Nazi-roleplay servers. The conversation closes on UFOs, alien contact, and disinformation, with the guest arguing that real anomalous phenomena are likely mixed with cover stories to make them dismissible, and that extraterrestrial framing may itself be a culturally limited narrative.

“If the AI gets so good that we can't tell the difference, then it becomes really tricky.”
“Now I think we're at least 70%.”
“But quantum mechanics says, "No, until we've looked in the box, the cat is in this state of superposition."”
“It's already doing that is my point.”
