Elon's new posts about things we can do in space with fully reusable superheavy vehicles are important. I have been wondering for years when he would realize that there are much more important things to do in space before building a city on Mars.
- Massive AI (and other) data
Elon Musk@elonmusk· Nov 2, 2025@rmcentush Starship could deliver 100GW/year to high Earth orbit within 4 to 5 years if we can solve the other parts of the equation.
100TW/year is possible from a lunar base producing solar-powered AI satellites locally and accelerating them to escape velocity with a mass driver.

We should not take survival on Earth too much for granted.
No commercial opportunity, however large, is more important than ensuring the long-term survival of consciousness, which becoming multiplanetary enables.
Space habitats require mass transfer from elsewhere to grow. Planets do not.
That said, a self-sustaining city on the Moon, while not as resilient to calamities that affect Earth as Mars (due to its proximity to Earth), is probably nonetheless worth the doing, in addition to Mars.
