Seasteading could be the means by which humanity will live sustainably.

Seasteads are man-made islands that float permanently on the ocean with any measure of a political autonomy. They would essentially be startup societies where people could form whatever kind of community they wanted.

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.

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.

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 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.
