[~39,000BC] Music - The Surprising History of Rhythm (that secretly created civilization)
09/04/2026 | 1h 10 mins.Did civilization start with a beat?
You might think music is a perfectly lovely but non-essential tool for survival and world domination. However, music might well be most misunderstood superpower of humanity. This episode explores one of the most impactful and overlooked inventions of history and how it shaped our species into the dominating power it is today.
Long before we were writing sonnets or splitting atoms, we were humming. The origins of rhythm gave our ancestors a staggering advantage. By singing and dancing, early humans flooded their brains with bonding chemicals, transforming isolated apes into cooperative powerhouses. They used melodies as ancient memory drives, encoding massive geographical maps and survival guides into memorable tunes.
Human civilization wasn't forged purely in grim struggle, but through the joyous, rhythmic act of making sound together:
Discover why the history of music is actually the history of human survival.
Learn how rhythm hacks your brain's memory systems to store crucial information.
Understand the psychological reason singing together builds unbreakable trust.
Hit play to discover how a simple beat built the modern world.

06/02/2026 | 42 mins.Why are we here? Can the patterns of history and nature tell us anything new?
In this episode of How to Change the World we trace a clear line. From ancient molecules learning to copy themselves, to religions and nations learning to spread, to algorithms that now compete for your attention. All on a subversive quest for immortality.
This hidden history of innovation maps the evolution of the universes most successful survivors. Learn the game theory of how these immortal beings compete and impact society.
This season has been about a species of hairy apes and how they became human. Today we combine science, history, and philosophy to build a set of mental models that explain the animal and human landscape of today and quite possibly tomorrow. The future of humanity depends on the decisions and innovations of today.
This episode will turn a lot of your ideas about the world on their head:
Have you ever considered that your genes don't exist to build you, you exist to build your genes?
Do you have ideas or do ideas colonize your mind - eating away at your attention just like we eat food to survive?
Is innovation more about what we spread, than what we invent?

03/12/2025 | 1h 2 mins.How humanity invented clothes. In the process, accidentally warping our psychology, sparking civilization, and changing what it means to be human forever.
A fish doesn’t know it’s wet, and a human doesn’t know they are hiding. But every morning, you participate in a ritual that separates you from nature, and your own biology.
For 90% of human history, we were naked. Then, in a blink of evolutionary time, we decided to cover up. This episode of How to Change the World challenges the standard narrative of invention stories.
We’ll explore:
Side effects: The invention of the needle to stitch leather went on to stitch the fabric of human civilization
Mental models: how one idea change the psychology of privacy, shame, and status
The Algorithm of Desire: How ancient fashion trends set the rules for modern attraction and power dynamics.
Join the deep dive into the psychology of change and the invisible lines that define our future society.

31/10/2025 | 29 mins.The most important innovations are invisible. Yet they are reliable building blocks of creativity that fuel human imagination.
The same 26 letter alphabet lets Shakespeare write a play, a researcher publish science or you can text your mum.
A standardised screw thread lets you build a house, a car or a space station.
This is the story of primitives; the fundamental components that make everything else possible. We explore how Jeff Bezos coining the term "Thinking in Primitives" as he invented AWS to the building blocks of the universe and life in it.
Join our tour through the weird and wonderful ideas of history as we gather ideas for how to build the future of humanity, space technology and anything you can imagine.
You'll learn:
By breakthroughs depends on invisible primitives created by someone before you
Why the most valuable opportunities are the ones everyone uses but nobody sees
How to identify foundational building blocks in any industry before competitors do
