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.

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.

People can leave seasteads, or people can choose them, and people can create new seasteads if they want. This fluidity will engage an evolutionary market process that'll allow a diversity of societies to emerge that will in principle be superior, simply because people chose them. Governments on land don't allow this fluid dynamic of choice.

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

I'm a novelist and science writer. I wrote a book about human impacts on marine mammals caused by agricultural drainage of nutrients on our coasts, and another book about evolution. Seasteading captivated me because it incorporates both evolution and environmental restoration.

Seasteads are a technology for anybody to form an alternative community based on their unique values - for communities to organize themselves however they want. Seasteads are their chance to demonstrate their vision can work. All that matters is that people can create, join, and leave seasteads voluntarily. As long as people can choose among seasteads, the best ways of living together will prosper, and the ones that people don't like will fail.

If seasteads advance blue-energy technologies, they'll create blue jobs. Millions of poor people living under exploitive governments are looking for a better choice. Seasteads won't attract them without offering them better options.
