In this episode, Samuel Arbesman speaks with Neal Agarwal. Neal has been building online playthings for most of his life. He runs neal.fun, which many listeners may already be familiar with, home to such games and internet toys as Infinite Craft and Internet Roadtrip. For example, Infinite Craft begins with the four elements of earth, air, fire, and water, which can be recombined in open-ended ways to build almost anything: water plus earth yields plant; plant plus fire equals smoke; smoke plus fire equals volcano—and then you’re off to the races. These websites are delightful, strange, and exciting, showcasing the sheer breadth of what the web can be.Samuel and Neal discuss Neal’s origins and history making things on the web, and how he came to build neal.fun full time. Their conversation explores the unique nature of the web as a medium, and what it means to take it seriously. This connects to the challenge of describing the internet toys Neal creates, since they represent something truly new and delightful. They also touch on programming, how AI might make building weird online things easier, the communities that have grown around Neal’s creations, and his process for designing these games. Along the way, they even consider fellow travelers in this world of fun online creations.

In this episode, Samuel Arbesman speaks with Julian Gough — a writer, musician, and now researcher in cosmology. Julian was part of Toasted Heretic, an Irish rock group, has written novels for both children and adults, and even composed Minecraft’s end poem. More recently, he has turned his attention to cosmology, exploring ideas at the intersection of evolution and universe formation to better understand why the cosmos is the way it is. He writes about this work in his newsletter The Egg and the Rock, where he argues that “our universe appears to be the result of an evolutionary process at the level of universes,” drawing on recent data from across many fields.Samuel and Julian discuss his career in music and writing, and how he gradually became drawn into big questions about cosmology. Their conversation explores cosmological natural selection, the idea of the universe as a developmental process, Julian’s blowtorch theory, and the challenges and opportunities of doing research outside the scientific establishment. Along the way, they consider the implications for our understanding of the cosmos, the role of intelligent life in the universe, how scientific paradigm shifts occur, and the value of interdisciplinary thinking.

In this episode, Samuel Arbesman speaks with Étienne Fortier-Dubois, a writer and programmer whose work has appeared in publications such as Asterisk Magazine and Works in Progress. He also authors the newsletter Hopeful Monsters. With a vast and eclectic set of interests—from the intricate details of technological history to the sweeping arcs of human civilization—Fortier-Dubois recently created The Historical Tech Tree, a website mapping the vast interconnections and interdependencies of technological advances across millions of years.Arbesman and Fortier-Dubois delve into the concept of a tech tree (and its connections to the game Civilization) and examine the nature of the tech tree he built. Their discussion ranges from decisions about what qualifies as a technology to the sources he used, as well as fascinating edge cases and stories uncovered during the project. They explore how such a tech tree can and cannot be used, its implications for education in technological history and literacy, and the potential for other kinds of “trees” to be constructed. The conversation also touches on worldbuilding, the so-called “illusion of complexity” in most fantasy and science fiction worlds, and how this perspective may have influenced Fortier-Dubois’s interest in history.

In this episode, Samuel Arbesman speaks with Chris Ferrie, an associate professor of quantum information at the University of Technology Sydney and the author of an impressive range of books for audiences of all ages — from adults and children to even babies. Ferrie is best known for Quantum Physics for Babies, but his prolific output spans titles such as Night Night Tyrannosaurus, Newtonian Physics for Babies, 42 Reasons to Hate the Universe (and One Reason Not To), and ABCs of Artificial Intelligence. The breadth of his work is astonishing.Their conversation explores Ferrie’s background and the origins of his science-for-babies books, but also ventures far beyond. They discuss his nonlinear approach to building a career, his comfort with embracing the strange and unpredictable paths his professional life has taken, and his thoughts on communicating ideas clearly. Along the way, they touch on scientific jargon and gatekeeping, the value of generalists, perspectives on education and its future, and the work of raising children.

Evan Armstrong, the insightful writer behind The Leverage, shares his journey from tech innovator to independent publisher. He explores the evolution of tech media and the role of newsletters in fostering authentic reader relationships. Evan emphasizes the need for deeper narratives and lyrical writing in a fast-paced digital age. The conversation also touches on the balance between technology and the humanities, the influence of AI in writing, and the importance of rekindling curiosity within the tech sector. His passion for merging beauty with substance shines throughout.

Gabe Henry, a writer and author of "Enough is Enuf," dives into the quirks of English spelling and its tumultuous history with simplification. He discusses notable figures like Benjamin Franklin and Noah Webster who aimed to reform English orthography. The conversation reveals the humor and challenges in spelling norms, the impact of technology on language evolution, and even explores playful approaches like emojis in writing. Henry and Samuel Arbesman debate whether spelling reform is a noble cause or just a slippery slope.

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.

In this episode, Samuel Arbesman speaks with Kenneth Stanley, a renowned computer scientist and AI researcher whose career spans academia, industry, and startup innovation. Stanley has been a professor, a cofounder of multiple companies, and a researcher at both OpenAI and Uber. He currently serves as the Senior Vice President of Open-Endedness at Lila Sciences. He is also the coauthor of Why Greatness Cannot Be Planned: The Myth of the Objective, a widely praised book exploring the nature of creativity and discovery.Arbesman and Stanley discuss the nuances of conducting research across a variety of organizational structures. Their conversation delves into the tradeoffs between traditional and novel research institutions, how to carve out space for exploratory or “weird” work within large organizations, and how research itself can serve as a tool for navigating disruption. The episode also explores the evolving role of open-endedness in AI research and what it reveals about the future of scientific and technological progress.

In this episode, Samuel Arbesman speaks with journalist and author Clive Thompson. Known for his thoughtful writing on science and technology—particularly in the realms of computing and programming—Clive contributes to Wired, The New York Times Magazine, Smithsonian, and more. He is also the author of Coders: The Making of a New Tribe and the Remaking of the World (2019).With the rise of generative AI and the emergence of “vibe coding,” their conversation turns to the evolving nature of programming and how Clive makes sense of it. They explore his early experiences with computers in the 1970s and ’80s, his temporary departure from coding, and his eventual return. The discussion ranges from creative coding and AI-assisted programming to computational thinking, the literary nature of code, and the future of coding education.

In this episode, Samuel Arbesman sits down with Alec Nevala-Lee, author of numerous books, including Inventor of the Future, a definitive biography of Buckminster Fuller.Buckminster Fuller was an architect, designer, and public intellectual whose influence stretched far beyond blueprints and prototypes. Later in life, he became a lodestar for the counterculture, inspiring the pages of the Whole Earth Catalog and leaving fingerprints all over what would become Silicon Valley’s ethos.In his biography, Nevala-Lee unravels Fuller’s contradictions — a visionary who struggled to succeed yet profoundly shaped culture, and who in many ways anticipated the archetype of the modern startup founder before such a figure existed.Samuel and Alec explore Fuller’s radical ideas in design, the curious saga of the geodesic dome, the “virtual corporation” Fuller orchestrated around himself, his sway over the tech world’s imagination, and how he played the role of a mystical, almost messianic presence amid the polished suits of the Mad Men era — and so much more.
