I think the huge thing that most people miss is that Elon isn’t trying to fix the earth’s problems. Elon is using the earth and other people’s money to bootstrap all of the things he needs to live on Mars. Every single one of his projects is in some facet working on a tech that is needed on Mars.

SpaceX gets you there.

Tesla gets you around there and batteries store power.

Solar City because batteries.

Boring Company to dig tunnels and create radiation safe locations for humans on mars.

Hyperloop cross country transport that doesn’t work well in our atmosphere but makes much more sense on Mars.

I think he is all consumed by his vision of humans surviving on mars and thriving. And when you look at things from this view suddenly his crazy becomes less crazy.
