I wonder if Musk will also be able to use it to manufacture future StarShips?

Reply to NASA Speeds Up Quest to Beat China to Mining Metals on the Moon by Gari_305

Issues:

you have to find the minerals you want

you have to get to them & mine them

You have to smelt them

You have to turn that lump into something useful

If you want to move it to anywhere else in the solar system you have to move it out of the gravity well that is the moon

& then there's moon dust - it's extremely toxic

Sure, give it a go & see what happens, but I'd rather be mining asteroids :)

Or at least be able to follow a passion. The catch is, who pays for it?

". . . Africa will be home to 40% of the world’s population . . . "

High population doesn't mean success. The world needs Africa to get it's act together, & hopefully it'll happen sooner rather than later - but it's a long way from guaranteed.
