The author of Sapiens sat down with Steven Bartlett to discuss the most important questions facing humanity — and his answers were equal parts fascinating and terrifying.
Yuval Noah Harari is one of the most influential thinkers alive. His book Sapiens: A Brief History of Humankind has sold over 25 million copies worldwide and fundamentally changed how millions of people understand human history. His follow-ups, Homo Deus and 21 Lessons for the 21st Century, tackled the future of technology and the challenges of modern life.
When he appeared on The Diary of a CEO, it became one of the podcast's most intellectually dense and thought-provoking episodes. Harari doesn't do small talk. He went straight for the big questions — and his answers will make you rethink everything you thought you knew about progress, technology, and what it means to be human.
Harari's central thesis, which he unpacked in detail with Steven Bartlett, is that humans dominate the planet not because we're the strongest or smartest animals, but because we're the only species that can cooperate in large numbers through shared fictional stories.
Money is a story. Nations are stories. Corporations are stories. Human rights are stories. None of these things exist in the physical world — you can't find a "corporation" under a microscope. But because millions of people believe in the same fiction, they can coordinate their behaviour on a massive scale.
"The most powerful force in the world isn't nuclear weapons or money. It's fiction. The ability to create and believe in stories that don't physically exist is what made Homo sapiens the dominant species on Earth."
This isn't a cynical observation. Harari doesn't say these stories are bad — human rights, democracy, and scientific institutions are all "fictions" that have made the world dramatically better. The danger comes when we forget they're stories and treat them as unchangeable laws of nature.
Harari drew a crucial distinction that most people miss. Every previous technology — from the printing press to nuclear bombs — was a tool. Humans decided how to use it. AI is different. For the first time in history, we're creating something that can make decisions and generate ideas independently.
He told Steven Bartlett that this isn't a future concern — it's happening now. AI systems are already deciding who gets loans, who gets hired, what news you see, and what products you buy. The question isn't whether AI will have power over human lives. It's whether we'll maintain any meaningful oversight over that power.
One of Harari's most controversial predictions is the emergence of a "useless class" — not useless in a moral sense, but economically useless. As AI and automation replace not just manual labour but cognitive work too, billions of people could find themselves with no economic function.
Previous technological revolutions (agricultural, industrial) displaced workers but created new types of jobs. Harari argues this time could be different because AI can learn and adapt faster than humans can retrain. The jobs AI creates might themselves be automated before humans can fill them.
His proposed solution isn't to slow down technology but to rethink our entire economic and social contract. Universal basic income, lifelong education systems, and redefining human worth beyond economic productivity are all necessary conversations we're not having fast enough.
Harari expressed deep concern about the concentration of AI power. If a small number of companies or governments gain a decisive advantage in AI capabilities, they could gain unprecedented control over human populations — not through force, but through understanding and manipulating human behaviour better than humans understand themselves.
"In the past, dictators couldn't follow every citizen 24/7. Now, with AI surveillance, they can. And not just follow them — predict what they'll do before they do it."
Harari spent a significant portion of the conversation discussing the collapse of shared reality. With AI-generated text, images, and video becoming indistinguishable from real content, we're entering an era where seeing is no longer believing.
This isn't just about deepfakes. It's about the fundamental erosion of trust. When you can't trust what you see, read, or hear, democratic societies — which depend on citizens having access to reliable information — start to break down. Harari called this "the end of the information age and the beginning of the confusion age."
Perhaps surprisingly for a historian known for big-picture thinking, Harari's most personal advice was about inner work. He's been practising Vipassana meditation for over 20 years — sitting for two hours every day and doing a 60-day silent retreat annually.
He told Steven Bartlett that in a world of increasing external noise, manipulation, and confusion, the ability to understand your own mind is becoming the most important skill a human can develop. If you don't know your own desires, fears, and biases, you'll be easy prey for algorithms designed to exploit them.
Steven was visibly affected by the conversation. He called it one of the most important discussions he'd ever had on the podcast. What seemed to hit him hardest was Harari's point that the decisions being made right now — in boardrooms, in government offices, in AI labs — will shape the next century of human existence, and most people aren't paying attention.
This episode is a wake-up call. Not a doom-and-gloom prediction, but an urgent invitation to engage with the biggest questions of our time before the window to influence the answers closes.
