Blake Scholl on Supersonic Flight and Fixing Broken Infrastructure - Live at the Progress Conference
Conversations with Tyler
Blake Scholl is one of the leading figures working to bring back civilian supersonic flight. As the founder and CEO of Boom Supersonic, he’s building a new generation of supersonic aircraft and pushing for the policies needed to make commercial supersonic travel viable again. But he's equally as impressive as someone who thinks systematically about improving dysfunction—whether it's airport design, traffic congestion, or defense procurement—and sees creative solutions to problems everyone else has learned to accept. Tyler and Blake discuss why airport terminals should be...

Donald S. Lopez Jr. on Buddhism
Conversations with Tyler

Sam Altman on Trust, Persuasion, and the Future of Intelligence - Live at the Progress Conference
Conversations with Tyler
for the Austin listener meetup Sam Altman makes his second appearance on the show to discuss how he's managing OpenAI's explosive growth, what he's learned about hiring hardware people, what makes roon special, how far they are from an AI-driven replacement to Slack, what GPT-6 might enable for scientific research, when we'll see entire divisions of companies run mostly by AI, what he looks for in hires to gauge their AI-resistance, how OpenAI is thinking about commerce, whether GPT-6 will write great poetry, why energy is the binding constraint to chip-building and where it’ll come from,...

Jonny Steinberg on South African Crime and Punishment, the Mandelas' Marriage, and the Post-Apartheid Era
Conversations with Tyler
Tyler considers Winnie and Nelson: Portrait of a Marriage one of the best books of the last decade, and its author Jonny Steinberg one of the most underrated writers and thinkers—in North America, at least. Steinberg's particular genius lies in getting uncomfortably close to difficult truths through immersive research—spending 350 hours in police ride-alongs, years studying prison gangs and their century-old oral histories, following a Somali refugee's journey across East Africa—and then rendering what he finds with a novelist's emotional insight. Tyler and Jonny discuss why...

George Selgin on the New Deal, Regime Uncertainty, and What Really Ended the Great Depression
Conversations with Tyler
George Selgin has spent over four decades thinking about money, banking, and economic history, and Tyler has known him for nearly all of it. Selgin's new book False Dawn: The New Deal and the Promise of Recovery, 1933–1947 examines what the New Deal actually accomplished—and failed to accomplish—in confronting the Great Depression. Tyler and George discuss the surprising lack of fiscal and monetary stimulus in the New Deal, whether revaluing gold was really the best path to economic reflation, how much Glass-Steagall and other individual parts of the New Deal mattered, Keynes’...

John Amaechi on Leadership, the NBA, and Being Gay in Professional Sports
Conversations with Tyler
John Amaechi is a former NBA forward/center who became a chartered scientist, professor of leadership at Exeter Business School, and New York Times bestselling author. His newest book, It's Not Magic: The Ordinary Skills of Exceptional Leaders, argues that leadership isn't bestowed or innate, it's earned through deliberate skill development. Tyler and John discuss whether business culture is defined by the worst behavior tolerated, what rituals leadership requires, the quality of leadership in college basketball and consulting, why Doc Rivers started some practices at midnight, his...

Steven Pinker on Coordination, Common Knowledge, and the Retreat of Liberal Enlightenment
Conversations with Tyler
Steven Pinker returns to Conversations with Tyler with an argument that common knowledge—those infinite loops of "I know that you know that I know"—is the hidden infrastructure that enables human coordination, from accepting paper money to toppling dictators. But Tyler wonders: if most real-world coordination works fine without recursively looping (a glance at a traffic circle), if these models break down with the slightest change in assumptions, and if anonymous internet posters are making correct but uncomfortable truths common knowledge when society might function better with noble...

David Commins on Saudi Arabia, Wahhabism, and the Future of the Gulf States
Conversations with Tyler
David Commins, author of the new book Saudi Arabia: A Modern History, brings decades of scholarship and firsthand experience to explain the kingdom's unlikely rise. Tyler and David discuss why Wahhabism was essential for Saudi state-building, the treatment of Shiites in the Eastern Province and whether discrimination has truly ended, why the Saudi state emerged from its poorer and least cosmopolitan regions, the lasting significance of the 1979 Grand Mosque seizure by millenarian extremists, what’s kept Gulf states stable, the differing motivations behind Saudi sports investments, the...

Seamus Murphy on Photographing Patterns Across Cultures
Conversations with Tyler
Seamus Murphy is an Irish photographer and filmmaker who has spent decades documenting life in some of the world's most challenging places—from Taliban-controlled Afghanistan to Nigeria's Boko Haram territories. Having left recession-era Ireland in the 1980s to teach himself photography in American darkrooms, Murphy has become that rare artist who moves seamlessly between conflict zones and recording studios, creating books of Afghan women's poetry while directing music videos that anticipated Brexit. Tyler and Seamus discuss the optimistic case for Afghanistan, his biggest fear when...

David Brooks on Audacity, AI, and the American Psyche (Live at 92NY)
Conversations with Tyler
David Brooks returns to the show with a stark diagnosis of American culture. Having evolved from a Democratic socialist to a neoconservative to what he now calls "the rightward edge of the leftward tendency," Brooks argues that America's core problems aren't economic but sociological—rooted in the destruction of our "secure base" of family, community, and moral order that once gave people existential security. Tyler and David cover why young people are simultaneously the most rejected and most productive generation, smartphones and sex, the persuasiveness of AI vs novels, the loss of...
info_outlineCarl Zimmer is one of the finest science communicators of our time, having spent decades writing about biology, evolution, and heredity. His latest (and 16th) book, Air-Borne: The Hidden History of the Life We Breathe, explores something even more fundamental—how the very air around us is teeming with life, from pollen to pathogens to microbes floating miles above the Earth.
He joins Tyler to discuss why it took scientists so long to accept airborne disease transmission and more, including why 19th-century doctors thought hay fever was a neurosis, why it took so long for the WHO and CDC to acknowledge COVID-19 was airborne, whether ultraviolet lamps can save us from the next pandemic, how effective masking is, the best theory on the anthrax mailings, how the U.S. military stunted aerobiology, the chance of extraterrestrial life in our solar system, what Lee Cronin’s “assembly theory” could mean for defining life itself, the use of genetic information to inform decision-making, the strangeness of the Flynn effect, what Carl learned about politics from growing up as the son of a New Jersey congressman, and much more.
