Elon Musk

Retired like a month before COVID hit.

And it was like the worst decision.

I had this vision that I was going to sit in cafes and study physics, which was my passion at the time.

And yeah, that didn't work because there were no more cafes.

I was just kind of stewing and kind of felt myself

spiraling, kind of not being sharp.

And then I was like, I got to get back to the office.

We're 260 today.

Time was closed.

But, you know, after a number of months, we started to have some folks going to the office and I started to do that occasionally and then started spending more and more time on what later became called Gemini.

which is super exciting, and to be able to have that technical, creative output, I think that's very rewarding, as opposed to if I, like, stayed retired.

I think that would have been a bad mistake.

We need to get about a million tons, is my guess, to the surface of Mars to make a civilization on Mars self-sustaining.

Again, to that critical point where if the resupply shifts from Earth stop coming for any reason, Mars still succeeds.

Mars can still grow.

And so you can't be missing anything.

You can't be missing even like the equivalent of vitamin C or anything.

You've got to have everything you need for Mars to grow.

That's essential.

So my guess is that's about a million tons, but it might be 10 million tons.
