Can a phone be a cow? It could in 1990s Bangladesh. This was the insight of a small number of mobile phone market pioneers who helped catalyze the spread of the greatest technological revolution in human history. Listen as George Mason University economist Philip Auerswald speaks to EconTalk's Russ Roberts about how the extension of connectivity to traditionally excluded populations led to wide-scale transformations in productivity. They discuss the role of little-known entrepreneurs such as Iqbal Quadir and innovators like Claude Shannon in bringing the mobile phone to the entire world. Other topics include William Nordhaus's paper on the cost of illumination as a powerful metric of human progress, Schumpeter's notion of innovation as new combinations, and what Auerswald calls the most important question the field of economics can ask: How much of human progress is inevitable, and how much depends on the determination of remarkable individuals?

Skin cancer comes from the sun. But so do many good things, according to author Rowan Jacobsen. Jacobsen talks with EconTalk's Russ Roberts about the health benefits of sunshine and makes the case for prudent sun exposure. Topics discussed include the "heliotherapy" movement that peaked in the early 1900s in response to rickets and tuberculosis, why diagnosing skin cancer is on the rise, and why yesterday's sunscreens may have done more harm than good.

Finding community can be difficult. But author Luke Burgis thinks the real challenge begins once we've found it and we're subject to social pressures to conform. Listen as Burgis and EconTalk's Russ Roberts trace the tension between individuals and their tribes through the foundational frameworks, such as family and school, that help forge our identities. Burgis argues that the disappearance of traditional rites of passage bodes ill for major life commitments such as marriage, and recounts his personal journey from Wall Street through the Great Books in search of a strong, differentiated self. He also draws lessons for today's communities from Saint Benedict's 1,500-year-old guide for monastic life and describes the moving ritual he practiced with his father before he died.

If you want to change the world, how you spend your 80,000 working hours may be the most important decision you can make. Benjamin Todd, founder of 80,000 Hours, joins EconTalk's Russ Roberts to dismantle the career advice you've been fed since childhood. "Follow your passion" turns out to be a trap. Chasing a big paycheck barely moves the happiness needle. And being a doctor has a smaller impact than you might think, says Todd. Todd and Roberts wrestle with the real ingredients of a fulfilling career--engaging work, supportive colleagues, meaningful problems--while debating whether Jeff Bezos has lived a worthy life and why most people won't part with 10% of their income to save lives abroad. Along the way, you'll meet unsung heroes like David Nalin, whose solution to dehydration saves millions of children's lives.

What does a lifelong atheist do when his dead father appears above him in the emergency room? Author and war reporter Sebastian Junger nearly bled to death in 2020 from a ruptured aneurysm, and what he saw in those moments sent him on a journey into physics, near-death experiences, and the nature of consciousness itself. In his third appearance on EconTalk, Junger discusses his remarkable book In My Time of Dying with host Russ Roberts. He reflects on covering wars from Sarajevo to Afghanistan, the strange phenomenon of dying people seeing the dead, and why he's still an atheist. Along the way, Junger offers a powerful meditation on terror and reverence, blessing and wounding, and why understanding life's fragility might be the most sacred gift of all.
