A podcast series about South Africa’s past, present, and future. Economic historian Johan Fourie and historical sociologist Jonathan Schoots interview social science scholars investigating fascinating questions about our country and continent and distil those lessons into practical policy suggestions today.
Why didn't slavery wither away? with historian Warren Whatley
If an enslaved person would pay above market price for their own freedom, why didn't the market produce abolition? How did a European trade good become a continent-wide arms race? Did Africa's underdevelopment and Europe's rise have the same cause?
In this episode of Our Long Walk, Johan Fourie and Jonathan Schoots speak with Warren Whatley, a Professor Emeritus of Economics at the University of Michigan and a leading scholar of the economic history of Africa and African Americans. His new book, Slavery, Freedom and Development: How Africa Became the Mirror Image of Europe (https://www.cambridge.org/core/books/slavery-freedom-and-development/247BC0CD08D2FEC6D9884E7F44FD4BBF)(Cambridge University Press), examines why the two sides of the Atlantic moved in opposite directions over six centuries.

Can A.I. speak Igbo? with computer scientist Chinasa T. Okolo
Imagine you're a Nigerian law student studying for the bar. You open ChatGPT. It can tell you, confidently, the capital of Arizona. It cannot tell you how a Lagos magistrate is likely to rule. About 52 per cent of the open internet is in English. Four or five other languages split most of the rest. Igbo is not on that list. Neither is Yoruba, Swahili, Amharic, or Ewe.
So whose questions does the model know how to answer, and whose does it fumble? Who decided what "general" intelligence means, and why does it keep speaking English?
In this episode of Our Long Walk, Johan Fourie and Jonathan Schoots speak with Chinasa T. Okolo, founder of TechnoCultura (https://www.technecultura.org/#), an AI and emerging technologies policy specialist at the United Nations, and a contributor to the World Bank's forthcoming World Development Report. She finished her PhD in computer science at Cornell, studying how non-expert users actually engage with AI. Her attention sits where the frontier labs do not look: the global majority.

BONUS: Live interview with Tyler Cowen
In this bonus episode of Our Long Walk, host Johan Fourie welcomes Tyler Cowen for a live interview recorded on 13 March at Stellenbosch University, in front of an audience of students and faculty. Tyler Cowen holds the Holbert Harris Chair of Economics at George Mason University, where he chairs and directs the Mercatus Center; he is the author of more than 20 books, co-founder of the blog Marginal Revolution and its companion online platform Marginal Revolution University, host of the podcast Conversations with Tyler, and founder of Emergent Ventures, a fellowship and grant program for social entrepreneurs.
The conversation opens with what South Africa can learn from Adam Smith on the 250th anniversary of The Wealth of Nations (from cutting red tape to start a business, to adopting a steady-growth "Denmark model" rather than chasing China-style booms), moves through Tyler's case that South Africa is safer and more culturally vibrant than international headlines suggest, and then turns to the role of AI in universities, the future of coding jobs, progress studies as a curriculum, how economists communicate ideas to the public, the social value of wine and declining alcohol consumption, and how Tyler now spots talent by asking candidates about their last few AI prompts rather than their open browser tabs.
