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

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.

You can't create the future unless you imagine it.

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.

That's the marvellous thing about seasteads; if a government fails, there's nothing much the people who live there can do about it. But if seasteads fail, they simply disassemble and go away.

I think our children will be living on floating cities, and they will look back on the 20th Century, when people lived in primitive governments founded in previous centuries, and they will be living on modular, sustainable, floating cities that we can't imagine now, that are based on the voluntary choice of citizens. I think we will have a marvellous world in the 21st Century.

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.
