#26 – W. Brian Arthur: On Economies, Santa Fe, and a Life in Ideas

Monday, December 15, 2025 • Duration 58:24

In the very first episode of Scaling Theory, I mentioned a few scientists who have shaped my understanding of the world. At the very top of that list is today’s guest: W. Brian Arthur.

Brian was born and raised in Belfast, Northern Ireland, and went on to become one of the most important figures of complexity science. Today, he is widely known as the father of complexity economics, a field that has transformed how we think about the evolution of modern economies.

His influence is remarkable. Brian’s work has been cited more than 58,000 times according to Google Scholar. He received numerous awards and recognition, such as being the inaugural laureate of the Lagrange Prize in Complexity Science, an award that many have described as complexity’s equivalent of the Nobel Prize. Brian has been, at age 37, the youngest endowed chair holder at Stanford University. He went on to work for my institutions, including the Santa Fe Institute, as we will talk about. On a personal note, I consider Brian a friend.

Now, what makes me especially happy to have Brian on the podcast is the unique perspective he brings on how economies form and evolve. His understanding of technology, how it emerges and scales, offers a lens that none others have developed. It is a way of seeing economic life as something alive. Be ready to be blown away.

#23 – Thibault Schrepel: Adaptive Regulation

Monday, September 29, 2025 • Duration 39:49

This is the first solo episode of Scaling Theory, where I take a deep dive into the literature. Building on a working paper titled “Adaptive Regulation,” I explore why “future-proof” laws so often fail in the face of rapid technological change, and how complexity science can guide us toward rules that adapt to the things they regulate. Drawing on recent EU digital acts and voices from law, economics, and complexity theory, I sketch the contours of a regulatory system that scales.

#14 – Eric Beinhocker: “New Economics” Is Coming For You

Monday, January 13, 2025 • Duration 47:05

My guest today is Eric Beinhocker, Professor of Practice in Public Policy at the Blavatnik School of Government, University of Oxford, and the founder and Executive Director of the Institute for New Economic Thinking at the University’s Oxford Martin School. Eric is the author of numerous academic articles and books, including The Origin of Wealth: Evolution, Complexity, and the Radical Remaking of Economics (2007).

In our conversation, Eric and I contrast traditional economics (neoclassical theory) with new economics (complexity economics). We also explore the policy implications of these differing economic theories, discussing topics ranging from aggressive growth strategies to complexity catastrophes in digital economies. I hope you enjoy our conversation.

#13 – Kevin Kelly: How Technology Evolves, And What To Do About It

Thursday, December 19, 2024 • Duration 35:14

My guest today is Kevin Kelly, the author of 14 books, a public speaker who has delivered TED talks with tens of millions of views, and a technology expert. In 1983, Kevin was hired by Whole Earth founder Stewart Brand to edit several later editions of the Whole Earth Catalog, the Whole Earth Review, and Signal. He later on served as the founding executive editor of the magazine Wired.

In our conversation, Kevin and I talk about the scaling laws behind all technologies, but also how these laws intersect with biology, society, and policy. We explore themes from What Technology Wants, we focus on the 'Triad of Evolution' and the concept of convergence, and connect these ideas to antitrust and innovation policy. I also touch on his earlier work, including New Rules for the New Economy, where we discuss the dynamics of trust in network economies and its implications for technology adoption. Finally, we delve into the inevitability of technological evolution, its accelerating diffusion, and what happens when technology becomes ubiquitous in society. These questions feel increasingly urgent as we approach 2025, a pivotal moment for revisiting these ideas in light of modern developments. I hope you enjoy our discussion.

#12 – Rory Linkletter: Scaling Up to the Olympics

Thursday, November 28, 2024 • Duration 48:25

My guest today is Rory Linkletter, a professional athlete who recently ran the Paris Olympic Marathon and the New York Marathon. Rory’s current personal best in the marathon is an impressive 2:08:01, which makes him the top Canadian marathon runner and the third-best Canadian performance ever.

This episode, as you might guess, is different from the others. I wanted to talk to Rory because he inspired me greatly when I went to Paris to watch the race. Most importantly, I am convinced that there is much we can learn from professional athletes, especially marathon runners.

In our conversation, we explore how Rory scaled his mental and physical abilities. I draw many parallels with the academic and policy worlds, delving into what we can learn from his process, the power laws he has identified, and his relationship with science.

Scaling Theory is not turning into a running podcast, but, true to its mission, it remains focused on exploring the scaling laws behind everything—be it economic, technical, or biological systems. Rory opens new doors regarding this last subject. I hope you enjoy our discussion.
