The Great Conversation

Hello everyone, and welcome to The Great Conversation. Some boundaries are easy to recognize when they are crossed. Others disappear one small step at a time. For years, European governments and NATO have faced what security officials describe as Russian “hybrid warfare”: actions designed to create disruption or pressure without necessarily looking like a conventional military attack. Cyberattacks. Disinformation. Damage to undersea infrastructure. Incendiary devices hidden i

Hello everyone, and welcome to The Great Conversation. For years, the conversation about artificial intelligence and work has revolved around one unsettling question: What happens when AI can do what we do? Write the report. Analyze the spreadsheet. Draft the contract. Create the presentation. Produce the code. But perhaps there is another question hiding underneath it. What parts of our jobs were never really about the computer in the first place? A recent Financial Times ar

Hello everyone, and welcome to The Great Conversation. For years, many of us have learned a simple nutritional equation: Less sugar is better. So when a product says “sugar-free,” it can feel almost automatically like the healthier choice. But what if the substitute deserves scrutiny too? New research presented at the European Society of Cardiology Congress 2026 has raised questions about xylitol, a widely used sugar substitute found in products ranging from sugar-free chewin

Hello everyone, and welcome to The Great Conversation. Sleep is one of the most ordinary things we do. Every night, we close our eyes and disappear from the world for several hours. But while we may think of sleep simply as rest, the brain is doing something far more complicated. During deep sleep, the brain clears metabolic waste, including amyloid-beta, a protein associated with the plaques found in Alzheimer's disease. Sleep also plays an important role in memory and cogni

Hello everyone, and welcome to The Great Conversation. Most of us use money every day without thinking very much about what it actually is. We work for it. We save it. We borrow it. We transfer numbers from one bank account to another and accept that something of value has changed hands. But what exactly gives those numbers value? In his article “The Hierarchy of Money,” Gregory Gundersen begins with a simple imaginary village using stones as money and gradually builds an ent

Hello everyone, and welcome to The Great Conversation. Imagine being hired to stand at the entrance of an office building, store, hospital, or public space. Most days may be uneventful. You watch. You observe. You help people. You maintain order. But then something happens. A confrontation. A robbery. An armed attacker. And suddenly, the person whose job may have seemed almost invisible becomes the person everyone expects to respond first. This is the uncomfortable contradict

Hello everyone, and welcome to The Great Conversation. We often associate breakthroughs in health with something new. A new drug. A new treatment. A new technology. A discovery that arrives from the frontier of science. But sometimes science turns its attention toward something that has been sitting on the dinner table all along. Consider beetroot. A recent Telegraph article explores the surprisingly wide range of potential health benefits associated with this ordinary root v

Hello everyone, and welcome to The Great Conversation. When we imagine a heart attack, many of us probably imagine the same scene. Sudden, crushing chest pain. A person clutching their chest. An emergency that is unmistakably an emergency. But what happens when the warning signs are much quieter? A recent Telegraph article explores a troubling problem in women’s health: symptoms of coronary heart disease can sometimes be mistaken for stress, indigestion, anxiety, or even the

Hello everyone, and welcome to The Great Conversation. Most societies prepare for problems by separating them. Energy policy over here. Food security over there. War and national security somewhere else. Technology and economic policy in another room entirely. But what happens when the problems refuse to remain separate? In a recent Telegraph analysis, Ambrose Evans-Pritchard describes what he calls four economic “horsemen” arriving at roughly the same time. War with Iran has

Hello everyone, and welcome to The Great Conversation. For years, hormone replacement therapy has occupied an uneasy place in discussions about women’s health. At one point, it was widely prescribed. Then major studies raised concerns about possible links to dementia, breast cancer, and heart disease, particularly when certain hormone combinations were started later in life. Use of HRT fell sharply. Now, new research is complicating that story. A large UK Biobank study follow

Hello everyone, and welcome to The Great Conversation. Some dangers announce themselves loudly. Others grow quietly in places where the world has stopped looking. Twenty-five years after the September 11 attacks transformed global security, The Telegraph reports that a different region has increasingly become a center of jihadist activity. Across parts of West Africa and the Sahel, particularly Mali, Burkina Faso, and Niger, militant groups have expanded amid political instab

Hello everyone, and welcome to The Great Conversation. Human beings have always tried to become more capable. We developed mathematics to calculate what our minds could not easily calculate. Machines to perform work our bodies could not perform. Computers to process information at speeds we could never match. And now, artificial intelligence may eventually present us with something fundamentally different. Not merely another tool that extends human intelligence, but potential

Hello everyone, and welcome to The Great Conversation. History rarely announces that one era has ended and another has begun. There is no bell that rings when an international order starts to disappear. Instead, there are signs. Wars that become harder to contain. Institutions that seem less capable of solving problems. Great powers increasingly testing the limits of accepted rules. Economic pressures. Climate extremes. New technologies advancing faster than the systems meant

Hello everyone, and welcome to The Great Conversation. When we try to understand why nations behave the way they do, we often begin with politics. We look at presidents, governments, ideologies, elections, alliances, and conflicts. But what if the story begins much earlier? Geopolitical Futures’ special report, The World Explained in Maps, begins with a deceptively simple idea: before listening to what nations say, look at the map. Mountains. Rivers. Deserts. Coastlines. Popu

Hello everyone, and welcome to The Great Conversation. For most of human history, intelligence has been one of our greatest tools for understanding the world. We used it to develop mathematics, medicine, philosophy, physics, and technologies capable of seeing farther into space and deeper into matter. But now humanity is attempting something different. We are building tools that may extend intelligence itself. Demis Hassabis, the London-born co-founder of DeepMind and one of

Hello everyone, and welcome to The Great Conversation. Sometimes the most remarkable stories of human progress begin with something that was never intended for the purpose it ultimately serves. NASA’s newly launched Nancy Grace Roman Space Telescope is one of those stories. At the heart of Roman is technology originally developed not to explore the universe, but to watch the Earth. In the years following September 11, the U.S. National Reconnaissance Office pursued an ambitio

Hello everyone, and welcome to The Great Conversation. Artificial intelligence is often discussed as though its future has already been decided. More powerful models. More capable machines. More businesses built around AI. And behind all of it, an enormous physical infrastructure is being constructed to make that future possible. Data centers. Chips. Power systems. Networks. And increasingly, debt. According to a recent Financial Times investigation, the global AI data-center

Hello everyone, and welcome to The Great Conversation. When we talk about artificial intelligence, much of the conversation focuses on what AI might replace. Jobs. Tasks. Perhaps even certain human skills. But there is another question worth asking: What could AI help us provide to people who never had enough of it in the first place? In a recent essay, Bill Gates turns to healthcare, particularly in sub-Saharan Africa, where the shortage of healthcare workers remains enormou

Hello everyone, and welcome to The Great Conversation. For years, artificial intelligence has lived mostly behind a screen. We open an app. Type a question. Ask for help. Then put the device away. But what happens when AI no longer waits for us to come to it? A recent Financial Times report explores the rapid growth of AI-powered smart glasses. Companies such as Meta envision glasses that can see and hear the world around us, giving AI assistants enough context to help us rem

Hello everyone, and welcome to The Great Conversation. Institutions depend on rules. But what happens when applying the rules appears to conflict with recognizing the individual standing in front of us? A recent Times report tells the remarkable story of Blerim Skoro, a Kosovan refugee who says he spent nearly a decade working undercover for American intelligence agencies. According to the report, Skoro infiltrated extremist networks connected to al-Qaeda and ISIS, operating
