Here’s the idea that will rewire your brain: money is a story. Not backed by a story. Not representing a story. Money is a story — a shared fiction that works because enough people believe in it. Yuval Noah Harari makes this case in Sapiens, and once it clicks, you’ll never think about Bitcoin (or dollars) the same way again.

The 70,000-Year View

Harari starts at the beginning — literally. About 70,000 years ago, something changed in the Homo sapiens brain. We developed the ability to believe in things that don’t physically exist: gods, nations, human rights, corporations. And money. This capacity for shared fiction is what let strangers cooperate at massive scale. It’s why a sapiens can walk into a store in a foreign country and exchange colored paper for food. Both parties believe the same story.

That framing alone is worth the book. But Harari doesn’t stop there. He calls the Agricultural Revolution “history’s biggest fraud” — it multiplied the total human population but made individual lives harder, shorter, and less satisfying. He traces how empires, religions, and trade networks knitted isolated tribes into a single global civilization, with money always serving as the most powerful unifying force of all. And he follows the thread through the Scientific Revolution, showing how the willingness to say “I don’t know” created the modern world.

The Bitcoin connection isn’t forced — it’s inevitable. If money is a shared fiction, then Bitcoin is a new fiction competing for belief. One with rules that can’t be changed by politicians or central bankers. One that might be more trustworthy precisely because it doesn’t require trusting anyone.

Why This Book Changes the Conversation

Read Sapiens and the question stops being “does Bitcoin have real value?” The question becomes: does any money have value outside of collective belief? And if not, which story do you want to believe in?
