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.

A lot of Pacific island nations are sinking below sea level; they could easily transition slowly into becoming floating nations.

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.

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.

Seasteaders bring a Silicon Valley sensibility to the problem of governments not innovating sufficiently. Innovators are held back and stymied by existing regulations, and we want to give them 21st century regulations on start-up governments.
