For fifty years, we’ve been told that nature is fragile — a porcelain Eden, easily shattered by the slightest human pressure. But history tells a different story. From the fall of Rome to the Black Death, from Chernobyl to Detroit, every time people retreat, the wilderness rushes back with astonishing speed. In this episode, we examine the reality that civilization is fragile while life on Earth is ferociously tenacious. Drawing on historians like Bryan Ward-Perkins and William Cronon, and ecologists like C.S. Holling, we discover how fast forests and animals can reclaim human spaces, and why the modern myth of a delicate planet misses the deeper truth. Nature is not fragile. Civilization is.

Phantom Worlds
History is full of phantom worlds—alternative technological paradigms that could have made everything turn out radically differently. Airships instead of airplanes. Rail instead of cars. Direct current instead of alternating current. Telegraphs instead of telephones. Each path once seemed inevitable, until another won out and reshaped civilization. In this episode of Context, we explore these turning points and what they reveal about our own moment, when autonomous vehicles and immersive virtual reality are racing forward in parallel. Will the future be built on radical mobility, or radical simulation? Or both? Most of all, we ask: what kind of lives do we want our grandchildren to live, and how will the choices we make now determine the answer?

The Machinery of Abundance
Modern life runs on hidden engine rooms—vast, intricate systems most of us never see. The Haber-Bosch process, which turns air into fertilizer, is one of them. It feeds billions, yet almost no one outside of science or industry could explain how it works or why it matters. In this episode, we explore Haber-Bosch not just as a technological marvel, but as a parable for our dependence on complex systems most of us barely understand. From the fight over bird droppings in the 19th century to the industrial alchemy of fixing nitrogen, we trace how human ingenuity transformed the limits of nature, and how that transformation fostered both abundance and fragility. This is a story about the machinery that sustains us, and the risks we run when we forget it’s there.

When We Were Most Human
The modern world is defined by acceleration. But what if the most stable—and perhaps most human—version of ourselves existed long before civilization? In this episode, we explore the world of the Cro-Magnon: anatomically modern humans who thrived in Ice Age Europe. For hundreds of generations, their way of life remained remarkably unchanged. What was it like to live in near-perfect evolutionary harmony with the environment? Civilization ultimately emerged as a hedge against danger, especially for those with children to protect. But in exchange for safety and surplus, we surrendered something more elemental and spiritually sustaining. This is the story of that trade-off—and of what we lost in the bargain. This is the story of a time before history began, when we were most human.

The History of the Future
Why did we stop believing in utopia? By the late 19th century, many Americans had come to believe that the future would be defined by peace, prosperity, and moral progress. But over the next century, optimism gave way to fear—war, nuclear weapons, and runaway technology began to reshape our vision of what was possible. In this episode of Context, we explore how our ideas about the future have evolved—from Edward Bellamy’s best-seller Looking Backward (1888), to H.G. Wells’ The Shape of Things to Come (1933), to The Terminator series (1984), and finally to Brian Christian’s The Alignment Problem (2020). Along the way, we trace the rise of techno-utopianism, the shock of dystopian realism, and the ethical dilemmas now posed by artificial intelligence. The history of the future has never mattered more. To support the show and access bonus episodes, join me on Patreon or subscribe through Apple Podcasts or Spotify.
