Daryl Gregory on Simulation Theory and the Great American Glitch Tour

In this episode, host Samuel Arbesman sits down with novelist Daryl Gregory, celebrated author of numerous science-fiction and fantasy works—including the newly released When We Were Real. Set seven years after humanity discovers that reality is a vast computer simulation, Gregory’s novel follows a cross-country bus tour of Americans seeking out the strangest “glitches” in their digital world. The story is wild, uncanny, and irresistibly imaginative—exactly the sort of narrative Arbesman is eager to unpack with its creator.

Together, Arbesman and Gregory trace the book’s origins and intricate world-building, delving into the unused catalog of “Impossibles” that never made it to the page. Their conversation ranges from philosophical reflections on the simulation hypothesis and how to find meaning within it, to the tantalizing prospect of breaking free from the code entirely. Along the way, they consider how the novel doubles as a lens on the United States itself—its eccentricities, excesses, and enduring weirdness.
