It doesn't take a planet-full of stuff to build a space city. And dragging it up a gravity well is an extra step.

- techdragon 4y agoI’m assuming an interstellar civilisation wants to build a lot of space cities and starships and anything else… like a lot on the sort of scale that justifies being an interstellar civilisation, enough space cities for trillions is going to take a lot of material. And as for the extra step… That’s why I said they might want to reduce that gravity well by breaking up the planet.
- mozey 4y agoOn earth advancements in technology, education, and especially woman's rights quickly lead to reduced or even negative population growth. So maybe interstellar civilisation won't need that many space cities
- techdragon 4y agoWho knows! Perhaps one of the necessary steps to conquering the distance between the stars is to develop robust robotics and the ability to somehow convert their consciousness into computer forms and cast off all the needs of their former fleshy bodies… vastly transforming the needs of such a society to primarily needing computers and energy for “sustenance”.
