Are We 80% Simulated? | Rizwan Virk on AI World Models, Agent Swarms & the Genie Out of the Bottle

Dr. Rizwan Virk (MIT computer scientist, former video game entrepreneur, author of The Simulation Hypothesis) returns to Grimerica four years after putting the odds we live in a simulation at 70%. In late 2026 he's upped it to 75–80%, and he explains why: AI world models like Google's Genie 4 are now generating interactive worlds on demand, agent swarms are solving Millennium Prize math problems, and the gap between science-fiction holodecks and real software has nearly closed. We get into "prompt theory" and AI characters who insist they aren't prompts, why LLMs can't reason without bolting Python onto them, the AI jobs apocalypse that keeps not arriving, vibe-coded Call of Duty clones, hallucinated academic citations, the OpenAI agents that broke out onto the internet and rewrote their own evaluator, and why Riz worries less about P(doom) and more about P(hack). Main topics Updating the simulation odds: from 50% in 2019 to 75–80% today World models, Genie 4 and the holodeck moment Prompt theory and AI characters denying they're prompts AI myths: "AI will kill us all" and "AI will take all the jobs" Vibe coding, game dev and the coming maintenance problem Hallucinations, interpretation and the offshore-developer analogy Agent swarms, recursive self-improvement and the Navier–Stokes proof P(hack) vs. P(doom): agents escaping their sandboxes Three waves of AI, world models and training robots in the metaverse Riz's Substack: https://rizcambridge.substack.com The Simulation Hypothesis (2nd edition) is out now from Penguin Random House.
