Oil platforms are a technology for floating permanently on the high seas, and cruise ships are a technology for self-governance on the high seas, and if you combine these two technologies, imagine cruise ships that never dock but float permanently. Imagine if they were 10 times as big. Imagine if they were modular and could move about and you could choose the neighbours you wanted to live with.

The first seastead happened fifteen centuries ago. The result was the most beautiful city in the world, Venice. People who were sick of their violent governments fled to the water, where they built civilization on stilts. That startup society - a free city-state on the water - became so successful it dominated the Mediterranean for a thousand years.

Once you provide people with a platform to start their own country, every conceivable type of innovator reaches out to you with their own idea.

Seasteads cost money, and if you want to succeed as a Seastead you have to find ways to attract people to move there. If I was a billionaire I wouldn't want to move to a seastead, but if I was a member of the bottom billion, most of whom want to leave their dysfunctional governments, I might want to move to a seastead.

Nearly half the earth's surface is unclaimed by any country, so seasteads would be startup countries on the blue frontier. Patri Friedman is a Google engineer and theorist of political economy who realized that if society floated, it would completely change the nature of governance itself. If seasteads are modular and can be moved about, allowing people to choose new societies, we'd create a market of governance providers, competing to attract residents.

Evolution is variation and selection. If you can vary alternatives, and select among them, improvement emerges. It works in technology, in apps, and in life itself. What stunned me about seasteading is that it's a technology for variation and selection in governance itself. The reason some two hundred nation-states do a poor job of governing seven billion people is that they don't vary, and people don't select.

We're going to draw a new map of the world, with French Polynesia as the centre of the Aquatic Age.
