Imagine greater Tokyo wrapped all over the surface of Phobos. Imagine dozens more industrial cities sprawling inside, under the surface of Phobos. An asteroid moon such as this could house tens of millions of humans – and post-human beings – in conditions far exceeding anything we can imagine today. It could be paradise.

Yet we are waiting trillions on keeping banks and governments afloat. I say – if you are in a hole, stop digging, get out of the hole and start using all those bricks to build a palace.

Yes we can.
