  Is AI the End of Mathematics, or Its Most Exciting New Beginning?

  Aug 20, 20261h 18m

  What does it feel like to watch an AI solve a problem in a single prompt that you've spent years working on, and produce a stronger result than your own published papers? Professor Kotlikoff grew up academically alongside two economists, Yuri Dadush and Michael Pomerleano, who were his classmates when he began his PhD at Harvard in 1973. In this episode, he sits down with their sons: Daniel Dadush , a professor of mathematics and optimization at Utrecht University, and Daniel Pomerleano , a professor of pure mathematics at UMass Boston, both of whom are watching AI upend their fields in real time. This is a conversation about what's actually happening inside mathematics right now: which problems AI has solved, how it solved them, what those solutions reveal about the limits of human specialization, and whether the next generation of mathematicians will bother showing up at all. What You'll Learn: [00:17:39] The moment ChatGPT produced a stronger result than two of Daniel Dadush's published conference papers: what happened in a single prompt session [00:31:13] The Erdos Distance Problem: open for 60+ years, solved by AI in a few pages, and why the ideas inside it cracked other problems too [00:35:39] The cycle double cover conjecture: an open problem with a short proof human mathematicians simply overlooked [00:36:26] Why AI proofs tend to be strikingly short: what that reveals about how differently machines approach mathematics [00:41:46] Why AI companies used math as their benchmark: what solving long chains of abstract reasoning was really designed to prove [01:00:39] The PhD thesis problem: how Daniel P. generated what would have been a strong thesis three years ago, in an afternoon, with a problem list and ChatGPT [01:08:46] Why pure mathematics may become a less attractive field for the next generation: and what's lost if that happens [01:09:23] The conference room scenario: an audience member spinning up 20 AI agents during a talk to answer the speaker's own research question before the talk ends [01:11:42] The policy question: NSF funding going to zero for economics while $200 billion flows to AI, and what hollowing out academic talent actually costs us Featured Guests: Daniel Dadush is a professor of mathematics at Utrecht University and leader of its Networks and Organizations Group. He completed his PhD in Algorithms, Combinatorics, and Optimization at Georgia Tech and held a Simons Postdoctoral Fellowship at the Courant Institute at NYU. He specializes in theoretical computer science and mathematical optimization. Daniel Pomerleano is a professor of mathematics at UMass Boston. He completed his PhD at UC Berkeley and has held positions at Imperial College London. His research focuses on mirror symmetry, symplectic topology, and non-commutative Hodge theory.

  Why Putin Can't Win, China Won't Fold, and Trump Is Running Out of Options

  Aug 6, 20261h 9m

  What if the three most dangerous regimes on earth — Russia, China, and Iran — are all weaker than they appear, and yet America is still losing ground to all three at once? Sir Niall Ferguson has spent a career studying how empires rise, overreach, and fall. He watched the Soviet Union collapse from the inside out while everyone in Washington assumed it would last forever. He's been warning about China's hidden fragility for years while the consensus said otherwise. Currently, he's watching the United States make the most conventional mistake of Donald Trump's entire political career: getting bogged down in the Middle East on the side of Israel, just like George W. Bush before him. Professor Kotlikoff and his old friend have a wide-ranging, rapid-fire conversation covering the real state of the Iran conflict, why a Taiwan semiconductor crisis is the single biggest threat to the world economy in the next two years, why Putin cannot win in Ukraine and knows it, why nuclear weapons won't be used, what Ferguson would actually tell Trump to do right now, and whether American universities brought the current backlash on themselves. What You'll Learn: [00:11:45] Why this is not World War III [00:13:50] The "American Suez" framework [00:17:00] Why there is no great military option left [00:19:15] The desalination plant vulnerability [00:22:00] The missile economics problem [00:25:00] The authoritarian axis [00:31:53] How the regime change in Iran already happened [00:34:15] Ferguson's actual policy prescription [00:45:11] Why Ferguson doesn't think China will overtake the United States [00:45:33] Cold War II and the Cuban Missile Crisis parallel [00:47:01] Why Russia is no longer a great power [00:48:00] Why Putin won't use nuclear weapons [00:53:35] The optimistic scenario [00:56:29] The university debate [01:01:26] The 75% to 35% collapse Sir Niall Ferguson is the Milbank Family Senior Fellow at the Hoover Institution at Stanford University and Senior Faculty Fellow at the Belfer Center at Harvard. He holds a DPhil from Oxford University and has taught at Oxford, Cambridge, Harvard, and Stanford. He is the author of 16 books including The Ascent of Money , Civilization: The West and the Rest , The Great Degeneration , Doom: The Politics of Catastrophe , and the two-volume biography Kissinger (volume two forthcoming).

  The Illiquid Jenga Tower: Inside the Private Credit Timebomb Nobody's Talking About

  Aug 2, 20261h 16m

  What if the passive investing revolution (the idea that just buying the index and holding is the smartest thing most people can do) has quietly turned into something that no longer resembles the efficient market it was designed to track? Every month, $33 billion flows automatically from 401(k) contributions into U.S. equity index funds. That money doesn't stop to ask whether Nvidia is fairly valued. It doesn't check whether 50% of the S&P 500 being tied to AI makes sense. It just buys, systematically and relentlessly, concentrating more and more capital into fewer and fewer companies — and in doing so, may be inflating the very market it's supposed to passively reflect. Professor Kotlikoff sits down with Jack Schibli , principal at Lane Generational, for a wide-ranging conversation about the structural changes quietly reshaping the U.S. stock market. From the mechanics of passive investing to the fragility of private credit, the vulnerability of the insurance industry, and the real competitive threat of Chinese AI to the trillion-dollar data center build-out Wall Street is betting on. This is original, ground-level analysis from an investor who's doing the work most institutional researchers aren't. What You'll Learn: [00:08:06] The "Illiquid Jenga Tower" — Jack's original deep dive into the fragility of private credit [00:12:20] Why the insurance industry could be the next AIG [00:15:01] The redemption gate hiding in plain sight inside private credit funds [00:19:19] What would actually need to happen for a systemic market event [00:35:33] The illusion of diversification inside your index fund [00:37:30] Why China is winning the AI cost war [00:42:56] The IP transfer problem nobody's discussing [00:46:49] How passive investing mechanically inflates valuations [00:47:44] Apple's $1.46 trillion buyback problem [00:51:18] The inelasticity trap — and why it only gets worse [00:54:35] The pod shop dynamic: 440% leverage and no long-term thinking [00:58:25] How retail investors became 20% of daily trading volume [01:02:51] Palantir at 310x earnings — and Lululemon's collapse in reverse [01:10:28] The causal chain that's flipped: the market is now running the economy [01:12:05] The Bessent paradox — criticizing Yellen for exactly what he's now doing Featured Guest Jack Schibli is a principal at Lane Generational, an independent registered investment advisor accessible through Fidelity Investments. He studied economics with a minor in computer science at Middlebury College, trained as a competitive ski racer, and began his career working with Lane Generational co-founder Fred Lane at Raymond James. He writes a quarterly investment research blog at lanegenerational.com/insights, known for its original structural analysis of market dynamics, private credit, and AI-driven disruption. His recent pieces include "Poker Face," "The Illiquid Jenga Tower," and several widely circulated posts on passive investing mechanics.

  Why the Most Important Economic Story of Our Time Isn't the Tariffs — It's the Institutions

  Jul 31, 20261h 10m

  What if one of the most famous and widely cited findings in modern economics (that money doesn't really make you happier) turned out to simply be wrong? And what does the economist who proved it wrong have to say about where America is heading next? Justin Wolfers is not a typical economist. He's written landmark papers on happiness, divorce, racial discrimination in NBA officiating, corruption in college basketball, gender and wages, prediction markets, and the political economy of elections. He runs one of the most widely read economics Substacks on the internet, co-authored a leading undergraduate economics textbook, and once showed Danny Kahneman data that changed the Nobel laureate's mind on a question he'd spent decades answering. In this episode, Professor Kotlikoff sits down with the University of Michigan professor for a wide-ranging conversation that moves from the science of happiness to the economics of marriage and divorce, the crisis facing young men, the future of American institutions under pressure, and a closing argument for why — despite everything — there has never been a better time to be alive.What You'll Learn What You'll Learn: [00:09:03] Why Gary Becker is the most important economist of the 20th century [00:17:51] The radical idea that economists should tell people what to do [00:20:00] The ice cream story that turned Justin into a behavioral economist [00:34:57] Why your grandmother said "opposites attract" — and why she was wrong [00:37:54] The divorce statistic nobody is talking about [00:40:05] Why the 1950s marriage model was the historical anomaly, not the norm [00:42:01] The Easterlin Paradox — and why it was wrong [00:58:21] The 60/40 gender split in college enrollment [01:01:16] Is there a crisis of masculinity? [01:04:48] Why attacking institutions is the most dangerous economic move America can make [01:06:51] The optimist's closing argument [01:08:32] Why Justin named his Substack "Platypus Economics" Resources Mentioned: Platypus Economics — Justin Wolfers's Substack, with a simple mission: teach the world economics in an accessible way that helps us all collectively understand it better: https://newsletter.platypuseconomics.com Principles of Economics (3rd Edition) by Betsey Stevenson and Justin Wolfers — Amazon: https://www.amazon.com/Principles-Economics-Betsey-Stevenson/dp/1429237864 Justin Wolfers's full research catalog — available at the National Bureau of Economic Research: https://www.nber.org (search "Justin Wolfers") Of Boys and Men: Why the Modern Male Is Struggling, Why It Matters, and What to Do About It by Richard V. Reeves — a Book of the Year according to The New Yorker and The Economist, and included in President Obama's 2024 summer reading list, tackling the structural challenges facing boys and men in education, the workplace, and family life: https://www.amazon.com/Boys-Men-Modern-Struggling-Matters/dp/0815739877 Featured Guest Justin Wolfers is a professor of economics and public policy at the University of Michigan, a research associate of the National Bureau of Economic Research, a non-resident senior fellow at the Brookings Institution and the Peterson Institute for International Economics, and a visiting professor of economics at the University of Sydney. He earned his PhD from Harvard University and his undergraduate degree from the University of Sydney, where he won the University Medal. Named by the IMF as one of the 25 economists under 45 shaping how we think about the global economy, he is the co-author of a leading undergraduate economics textbook and the author of the widely read Substack Platypus Economics .

  Social Security Is Broke. Here's What That Actually Means for Your Check

  Jul 29, 20261 hour

  The headlines say Social Security is running out of money. But what if the real numbers are actually far worse than what the headlines are showing you, and the trustees' report is burying the truth in an appendix table that almost nobody reads? The 2026 Social Security Trustees Report just dropped, and the media coverage has been loud, alarming, and, still understating how serious the problem actually is. In this Substack Live conversation, personal finance journalist and retirement specialist Pam Krueger sits down with Professor Kotlikoff to cut through the noise, decode the actual math, and answer the question every pre-retiree and current beneficiary is asking: what does this mean for me? This is not a doom-and-gloom session. It is a clear-eyed, numbers-first look at what the system is, why it is broken, what fixing it would actually require, and what you can do right now to protect yourself. What You'll Learn: [00:06:26] The table buried in the Trustees Report that tells the real story — Table VI F1, hidden deep in the appendix, reveals the system needs a 46% payroll tax hike, not the 22% benefit cut the headlines are running with [00:08:54] The difference between the 2032 cash flow problem and the real, permanent problem — why the 22% cut number is actually the short-term version, and the true immediate fix requires a 31% permanent benefit cut starting today [00:10:01] Will Social Security checks actually stop? — the straight answer, with context on what "enough money to pay 70% of benefits forever" actually means for your household [00:12:11] How the pay-as-you-go system actually works — a plain-language breakdown of FICA taxes, covered earnings, the trust fund checking account, and why the demographics have turned against the whole structure [00:16:00] Why fertility rates are at the heart of this crisis — the U.S. fertility rate has dropped from 2.1 to 1.59, and what that means for the number of workers available to fund your retirement [00:17:23] The Ponzi scheme history nobody taught you — how every president from Eisenhower to Nixon took turns goosing benefits when the baby boom made it look affordable, and locked in promises the system can no longer keep [00:25:44] What younger workers should actually expect — Social Security will likely exist, but the tax burden on younger generations is the real threat, not elimination of the program [00:34:39] Why simply lifting the payroll tax ceiling is not the silver bullet it sounds like — and who actually gets caught in the crossfire [00:43:00] Larry's Personal Security Account proposal — a Singapore-style fully funded replacement for the current system, modeled on what major U.S. corporations did when their own pension Ponzi schemes ran dry in the 1970s and 80s [00:51:54] The three radical fixes that could actually work — reform Social Security at its core, adopt a Scandinavian-style healthcare system, and overhaul the tax structure. Tweaks will not cut it. Featured Guest: Pam Krueger is a personal finance journalist, entrepreneur, and co-host of the podcast Friends Talk Money with Terry Savage and Richard Eisenberg. Her Substack, Count Up with Pam Krueger, focuses on practical retirement preparation for people in the years leading up to retirement.
