In a world with a functioning World Model, the most pervasive interface isn’t a screen. It’s a sound. A hum. The ambient knowledge that for any decision, any path, you could, in principle, run a simulation. You could know the outcome. This Hum of the Possible becomes the new background noise of existence. And it changes the quality of every choice, making it feel provisional, unreal.Why commit to a relationship when you could simulate a thousand alternatives? Why choose a career when you could model your satisfaction in all of them? The ability to know, or to think you can know, vacuums the risk out of life. And risk is the oxygen of meaning. Without it, commitment suffocates. We become eternal browsers in the catalogue of possible lives, paralyzed by the hum of the unwalked path.The interface to this is silent but total. It’s the psychic affordance the model gives to every moment. The little “what if?” that floats over every decision. To combat this, we might have to build interfaces of commitment—physical or digital rituals that deliberately shut off the hum. A button you press that says “NO SIMULATION” and locks you into a choice. A marriage ceremony that includes wiping the predictive profiles for both partners. We’ll need ways to carve out silence from the relentless hum of possibility.Otherwise, we live in a permanent state of counterfactual nostalgia—grieving for the lives we didn’t live, which the model can describe to us in perfect, heartbreaking detail. The most valuable interface might be the “IGNORANCE” switch.My controversial take is this: The ultimate luxury good in a modeled world will be authentic surprise. Events that the model did not, or could not, predict. People will pay fortunes to attend live, un-simulated theater where the script changes nightly based on the actor’s whim. They’ll seek out “black box” experiences where no data is collected, no outcomes are projected. The richest won’t flaunt their access to prediction. They’ll flaunt their ability to opt out of it. They’ll live in the quiet, expensive silence on the other side of the hum, where life feels real, precisely because it is unknown.This has been The World Model Podcast. We don’t just gain the power of prediction—we must fight to preserve the sacred, silent right to not know. Subscribe now.
