Jean-François Noubel calls himself an ‘open source earthling’. Though he lives in France, he considers his true home to be within himself. Like a turtle. And though he lives within a market economy, he chooses to live as much as he can in a gift economy instead, without money. But why? As a researcher of collective intelligence, Jean-Francois sees currency as the tool that informs the design of human society. He believes we have to expand our concept of wealth and redesign the currencies that connect us to create economics systems that are fair, civil, and transparent.
