November 05, 2025 MIT Economist Jon Gruber on AI, Trade-offs & Healthcare
Prof. Jonathan Gruber, our guest for this episode, likes to tell his students that economics is a fundamentally right-wing science. What he means by that is that classical economics is built on one powerful explanatory insight: that free markets—networks of buyers and sellers, producers and consumers, weighing the trade-offs of different options and making self-interested choices based on supply and demand—do a better job of deciding how to allocate resources than can be achieved by a top-down, command-economy approach. But as Gruber goes on to explain, that principle only holds when all participants have equal access to markets and to information; in the real world, imbalances in that access lead to market failures, inefficient allocations of resources that leave most people worse off than they would otherwise be. That’s why government regulation still has a role in a properly functioning economy. Tune in to hear Prof. Gruber explain why we need “capitalism with gutter guards” to ensure equitable outcomes, especially in sectors of the economy such as healthcare where the ideal markets envisioned by classical economics are particularly unattainable or undesirable.

May 14, 2025 MIT Programmer Ana Bell on Growth Mindset, Coding, and Rubber Ducks
Learn about Python, growth mindset, and the uses of rubber ducks in this interview with MIT lecturer Ana Bell. Dr. Bell, who has been programming since she was twelve and now teaches popular introductory courses in computer science, says that coding consists of almost equal parts creativity and logic. The creative part, she explains, gets exercised particularly when you have to come up with an algorithm to solve a given problem, because for any given complex problem there are many possible approaches to tackling it. The logical part comes into play when you sit down to translate that algorithm into an unambiguous sequence of rules in a programming language, and again when you discover that the code you’ve written doesn’t work exactly as you intended it to and you have to set about debugging it. Among the topics the conversation addresses are why everyone–even in the age of generative AI– ought to study at least the basics of programming, why it can be useful to speak to an inanimate object when your coding project is stuck in the debugging stage, and how programming can help you choose your own adventure.

April 16, 2025 MIT Economist Andrew W. Lo on Finance, AI, and Human Behavior
In this the first of two pilot episodes of Chalk Radio with VIDEO, Professor Andrew Lo, who teaches finance at MIT’s Sloan School of Management, knows that many people find financial matters perplexing and scary. Lots of us don’t have a good head for numbers, and besides, how can one get advice and make sound decisions when it’s taboo to discuss one’s finances at all? That’s where a financial advisor is useful–someone who understands the concepts, can crunch the numbers, and has a fiduciary responsibility to look out for your best interests. For many people, hiring a financial advisor might be a financial impossibility, but Prof. Lo and his colleagues are working to develop an AI financial advisor that not only gives ordinary people access to sound financial advice, but acts with real fiduciary responsibility. Large language models can’t do this yet, he says, but the technology is developing fast. Other topics he touches on in this episode include the outsized influence of finance on drug development and global decarbonization and the equally outsized influence of teachers on their students–he names many who changed his own life, from his third-grade teacher in Queens to his professors at college and graduate school.

December 18, 2024 Sujood from Sudan: An Open Learner's Story
Sujood Khalid Eldouma recently relocated to the UK for her master’s studies, having previously lived in Egypt after fleeing her native Sudan to escape the devastating civil war in that country. Sujood holds a bachelor’s degree in electrical engineering from the University of Khartoum, but her ambitions extend far beyond the field she was trained in. She recently graduated from the MIT Emerging Talent certificate program in Computer and Data Science and is pursuing a MicroMasters in statistics and data science through the support of MIT Emerging Talent. In this episode, we hear how Sujood and her classmates at the university in Khartoum used MIT OpenCourseWare lecture videos as the basis of a group learning experience, in which knowledge was shared and lasting friendships were formed. We also hear how Sujood is pursuing her current online studies not just as a means of self-improvement but as part of the groundwork for a much bigger, future project: helping to rebuild Sudan’s educational and scientific infrastructure when peace comes to that country. “I'm not doing it just for myself,” she says. “I'm not doing it just for my family, but in the bigger picture and with a heart filled with hope.”
The Open Learners podcast is produced by Alexis Haut and hosted by Emmanuel Kasigazi and Michael Jordan Pilgreen.

December 04, 2024 Jerry from Uganda: An Open Learner's Story
They say every crisis also presents an opportunity. Open learner Jerry Vance Anguzu seized one such opportunity in the midst of the Covid-19 pandemic, when his native country of Uganda went into lockdown. Jerry was stuck at home, unable to earn a living, but that enforced inactivity gave him the chance to pursue new directions in his education. A few years earlier, he had discovered MIT OpenCourseWare and had seen what it had to offer; now he returned to MIT Open Learning resources in earnest, plowing through courses in data science and computer programming; soon thereafter he was accepted into the MIT Emerging Talent certificate program, where he began to develop an interest in entrepreneurship. Now, just a few years later, Jerry has his own startup, Everpesa Technologies, a financial services platform that offers sustainable investment opportunities and financial literacy resources to people in sub-Saharan Africa. Along the way, he has become a self-described “OCW ambassador,” enthusiastically spreading the word to relatives and colleagues about the learning resources that are available online through MIT OpenCourseWare. “You don’t need to pay anything,” Jerry tells them. “You just need to have a bit of time.”

November 13, 2024 Lotfullah from Afghanistan: An Open Learner's Story
Our guest for this episode, Lotfullah Andishmand, grew up in a village in rural Afghanistan where there was no internet access or electric lights. (He describes having had to navigate by moonlight to get to his uncle’s house for tutoring in chemistry.) In search of educational opportunity, he eventually moved to Kabul, where he discovered MIT OpenCourseWare’s lecture videos while studying electrical engineering at the university. Even there, though, the internet infrastructure was shaky enough that Lotfullah often resorted to downloading the course materials so he could study them at leisure when broadband wasn’t available. He now resides in India and recently graduated from the MIT Emerging Talent certificate program in Computer and Data Science, specifically designed for displaced communities worldwide. As he continues his educational journey in data science and artificial intelligence, he remains deeply mindful of the challenges he encountered as a student in his home country. Recognizing that most of the available online educational resources are in English, a language few Afghans are fluent in, Lotfullah has used his computer skills to create an online learning platform offering educational materials in Persian. Someday, he hopes the platform will expand to include full online courses with direct interaction between instructors and students.

October 30, 2024 Nader from Jordan: An Open Learner's Story
When Nader AlEtaywi was in high school in Jordan, he had a passion for finance but his prospects seemed limited. Juggling his studies, minimum-wage jobs, and family crises made it hard to envision a future where he could develop his talents and flourish in his chosen field. Through sheer perseverance he finished high school and entered university, where during the Covid pandemic in late 2020 he discovered the world of educational resources that MIT Open Learning offers. He devoured MIT OpenCourseWare courses in statistics, computer programming, and calculus, and soon realized that he could take steps toward a career in finance by enrolling in a MITx MicroMasters program. The program’s instructional team recognized Nader’s talent, and when he finished the program they offered him a position as a teaching assistant. From there, drawing on the skills he had learned but also on the online community he had become a part of, Nader was able to get jobs in his field, first working for a financial firm in Jordan, and then for companies in the US and Dubai. In this episode, we hear his inspiring story of passion and perseverance.

October 16, 2024 Jae-Min from South Korea: An Open Learner’s Story
Jae-Min Hong, our guest for this episode, is a hungry learner with wide-ranging curiosity and a distrust of groupthink. A native of South Korea, she has been fluent in English from childhood, which has opened up many educational possibilities for her. Aiming to widen her cultural horizons, she opted to attend high school in New Zealand; a few years later, she transferred from a Korean university to an American one so she could attend in-person classes during the Covid pandemic. With the help of lecture videos from MIT OpenCourseWare, Jae-Min was able to supplement her formal studies and pursue all the subjects that interest her, from chemistry and thermodynamics through data science and financial technology. She’s now back in South Korea, where she’s finishing a degree in economics at Yonsei University. She feels it’s time for her to really focus her attention on a single field and a single goal, a career in investment banking. But if that doesn’t work out, she says, she can always come back to MIT OpenCourseWare and dip once more into the wealth of resources it has to offer.

October 02, 2024 Maria from Brazil: An Open Learner’s Story
In this inaugural episode of the Open Learners podcast, hosts Emmanuel Kasigazi and Michael Jordan Pilgreen interview Maria Eduarda Barbosa, a medical student located in Rio de Janeiro, Brazil. Maria tells in her own words how MIT OpenCourseWare changed the trajectory of her life, particularly how she might never have achieved her full potential if one of her teachers had not recognized her abilities and urged her to pursue more challenging studies. Googling “Calculus introductory course,” Maria discovered one of Prof. Gilbert Strang’s videos on MIT OpenCourseWare, and it opened a vision of new horizons for her. She became a near-daily user of MIT OpenCourseWare, and the experience transformed her intellectual life, inspiring her to become passionate about her own education and to share that passion with others around her. Maria describes how the experience has not only awakened her curiosity and self-motivation, but also given her a better attitude about the gaps in her existing knowledge. Now, she says, she doesn’t think, “Oh, I'm lost because I'm stupid”; instead she thinks, “I'm lost because I haven't learned this yet.”

September 25, 2024 Introducing the Open Learners Podcast
Emmanuel Kasigazi is a data scientist from Kampala, Uganda. Michael Jordan Pilgreen is a financial technology engineer from Memphis, Tennessee. Kasigazi and Pilgreen know firsthand how transformative open learning can be: Pilgreen’s discovery of the free educational materials at MIT OpenCourseWare helped him develop new technical skills and eventually led to a new career in a field he is passionate about, while Kasigazi has enjoyed MIT OpenCourseWare’s wealth of lecture videos on YouTube for years, not only to learn within his field but also to immerse himself in the deep questions of psychology and philosophy. In this episode we hear from Kasigazi and Pilgreen about how open learning changed their lives and how they became friends and colleagues despite living on opposite sides of the world. We also hear of their new project, in which they’ll be teaming up to host an upcoming special season of Chalk Radio. Unlike the typical Chalk Radio season, which focuses on the supply side of open learning, featuring interviews with inspired educators at MIT, this special “Open Learners” podcast season will focus on candid conversations with open learners from all over the world. This special season is coming Fall 2024. Don’t miss it!
