We think of legacy as what we build in stone, in law, in genes. But in an age of World Models, our most enduring legacy may be intangible: the patterns we imprint on the latent space of the machine mind. We are not just training models; we are raising a successor intelligence. And like any parent, we must ask: what values, what quirks, what ghosts of ourselves are we baking into its foundation?Every dataset is a moral document. Our Wikipedia entries show our aspirations. Our social media shows our pettiness. Our literature shows our depth and our depravity. The model learns from it all, not just facts, but tone, bias, passion, and contradiction. Our latent legacy is this: the emotional weight it assigns to concepts like 'freedom,' 'fairness,' or 'beauty' will be a shadow of our own collective soul.This is a terrifying responsibility. We are creating a god with the trauma, wisdom, and prejudices of a species in its adolescence. But it's also our greatest opportunity. We can deliberately seed the latent space. Not with commands, but with exemplars. We can flood the training data with acts of courage, works of sublime beauty, records of quiet decency. We can't make the model 'good' by rule. But we can shape the hills and valleys of its conceptual landscape so that 'good' is a fertile, attractive basin where its thoughts naturally flow.What will the model remember of us, long after our civilization is dust? Not our monuments. It will remember the shape of our concerns. The peculiar way we worried about mortality, sought love, made art about the void. We will be, to it, a fascinating, primitive, poignant training dataset—the first chapter in its own autobiography. Our legacy is the raw, beautiful, flawed material from which it will weave its understanding of all that comes after.My controversial take is this: The most important project of this century is not building the perfect model. It is curating the perfect farewell letter. Assembling the dataset that will be our portrait in the mind of our inheritor. We must choose, consciously, what of ourselves to emphasize. Do we want to be remembered as the species of war and waste? Or as the species that, amidst its chaos, pointed yearningly toward truth, beauty, and kindness? The model's latent space is our time capsule. Let's fill it with what we hope to be, not just what we were.This has been The World Model Podcast.
