How to Change the World: The History & Future of Innovation

How To Change The World

If you want to change the world, you need to dissect the past to build a blueprint for tomorrow. Follow the epic journey through the history of invention, science and technology - told in chronological order. --- Long before the rise of Empires, before the invention of the written word and before humans ever tamed fire. Curiosity was shaping the fate of our species. This podcast breaks down the messy, complicated, often accidental ways humanity pushes forward—and shows you exactly how you can do the same. This isn’t surface-level history. Starting at the dawn of civilisation, we trace the thread of human innovation in the order it happened. Covering the stories of the world's greatest inventors and most powerful ideas. Each episode is a masterclass - with all the nerdy details and side-quests that matter across science, economics, psychology and more: From Maritime navigation to Interstellar explorationHammurabi’s legal code to Algorithmic governanceDa Vinci’s human dissection to Genome editing Studying the patterns of history and invention shows how every world-changing idea is but a conversation between what has been and what could be. Journey with us as we untangle the playbooks of the disruptors who change things here on earth and beyond. Hosted on Acast. See acast.com/privacy for more information.

    [Stone Age] - Innovation Locks: The 5 Progress Blockers for 97% of Human History

    What lies at the core of human progress? This episode sets the scene for all human innovation. For 3.5 million years, humans and our ancestors were stuck in the Stone Age. We cover: What were we busy with for 97% of our existence?Why were we so slow at innovating?How did we eventually overcome these fundamental forces? From personal pressures to global forces, we trace the blocks on human development. The answers hold many insights for today when we think about innovation and how to make progress..

  3. Innovation Richter Scale: How Much Do Technology and Ideas Change World History?

    EPISODE 3

    Innovation Richter Scale: How Much Do Technology and Ideas Change World History?

    How to rank the impact of innovations on humanity and how much they really changed the world. Everything seems so important these days: A new iPhone update changes EVERYTHINGThis war will BREAK the economyIf you feed your toddler THIS, you don't deserve to be a parent... Learn to rationally understand what matters to humanity and what is just noise. It's easy to tell that the invention of Writing itself is more important than Velcro. But... Is Netflix more important than Baseball?Has TikTok changed the world as much as the Longbow?Was Steve Jobs more impactful than Henry VIII? History has opinions. So it's time to build a scale that lets us rationally measure global impact. Introducing the Innovation Richter Scale - a 1 to 10 rating system that lets you rank absolutely anything you can think of. NOTE - This episode expands on the Technological Richter Scale proposed by Nate Silver. (see references) ABOUT How to Change the World is an independent podcast on a mission.

  4. [~1.8 Mya] - Fire: The Innovation that Forged Humanity and Sparked World Domination

    EPISODE 4

    [~1.8 Mya] - Fire: The Innovation that Forged Humanity and Sparked World Domination

    Do we really control fire? While you're patting yourself on the back for lighting that barbecue, fire has been pulling the strings for 2 million years, reshaping our anatomy, rewiring our brains, and dictating our social structures. It transformed us from ape-like creatures that had a neat standing trick into the cunning apex predator of the world. Along the way, it upended both ecosystems and gender roles but most importantly, made us human. The lesser-known of fire is that an individual human is completely dependent on it to survive. Furthermore, Society itself is built on fire and would collapse totally without it Today, as we face the dawn of AI, we're seeing the same pattern. Fire marked a huge leverage of energy that freed us up to think. AI promises to do our thinking for us, which frees us up for who knows what. aren't tools we use; they're partners that reshape us from the inside out. Three takeaways: Transformative technologies change what we are, not just what we doDependency often disguises itself as control and masteryThe biggest innovations create irreversible psychological and social shifts Ready to understand how fire forged the human mind?

    EPISODE 5

    The Laws of Nature: 3 Rules Governing the Success of Any Organism, Idea & Technology

    Why do some ideas and technologies proliferate, whilst others die painfully? Innovations aren't just bound merely the laws of Physics, but also the powerful laws of Nature and Biology. In the "Lessons of History", Will and Ariel Durant propose the 3 Laws of Biology. Extending on the work of Charles Darwin, they explain the rules that govern life on earth and how it applies to humanity. In this episode, Sam extends the concept whilst also explaining a brief history of life on Earth whilst he's at it. In it, you'll learn the fundamental rules of competition, selection and reproduction that govern the success of any organism, idea or technology. We'll explore Why did Julius Caesar care so much about fertility rates?Your secret past life as the most epic dinosaur, the SupersaurusWhat causes unbridled Capitalism or Communism to failIs equality even good thing? And if so what do we do about it... ABOUT How to Change the World is an independent podcast on a mission to document the entire history of innovation. One world-changing event at a time.
