World Models excel at prediction—simulating the future. But what if we could run them in reverse with equal fidelity? Not just remembering, but re-simulating the past, not as a fixed recording, but as a dynamic, queryable reality. This is the Temporal Model: a reality engine that treats time as just another dimension to navigate, allowing us to walk into yesterday and ask 'what if' with the same certainty we ask about tomorrow.The model is trained on the causal graph of reality. It knows not just what happened, but the precise probability distributions of what could have happened at every branching point. You don't ask 'Who killed JFK?' You ask: 'Simulate Dallas, November 22nd, 1963. Run 100,000 counterfactual scenarios. What is the Bayesian probability of a second shooter, given all known evidence and the physics of ballistic trajectories?' The model renders the past, not as history, but as a multiverse of might-have-beens.This turns history from a discipline of interpretation into a laboratory of causality. We could solve cold cases by simulating every possible perpetrator. We could understand the true impact of historical figures by simulating their absence. We could experience, in immersive simulation, the lives of our ancestors with staggering detail, inferring their unrecorded thoughts from the constraints of their world.But this power corrupts. What happens to justice when we can perfectly simulate a crime and assign probabilistic guilt? What happens to identity when you can re-simulate your own childhood and see the exact moments that shaped you? The past becomes plastic, editable, no longer a foundation but a playground for revision.My controversial take is this: The Temporal Model will destroy history and create Chronocracy—rule by those who control the definitive simulation of the past. The winning narrative will no longer be written by historians, but by whoever owns the most accurate model. Nations will fight wars not over territory, but over the weighting of historical training data. 'The Great Man Theory' vs. 'Social Forces' will cease to be academic debates and become parameters in a world-shaping simulation. We will cease to learn from the past, and begin to program it."This has been The World Model Podcast. We don't just record time—we build the engine that can make it run backward, and in doing so, risk unmaking the meaning of time itself. Subscribe now.
