> Luxembourg is very bullish on asteroid mining. They think it’s gonna be a huge business five, ten, fifteen, twenty years from now. That timeline seems comically bullish. What's the biggest thing we've brought back to earth on an unmanned mission to date? Probably a few grams of asteroid dust. That timeline is maybe right for autonomous cars, but I doubt we'll see mining on an economically significant level in any of our lifetimes. It just doesn't make sense from a cost perspective when we have plenty of resources on earth that can still be extracted. I guess you can make a case for doing it to learn how to build things in space, but again, the engineering hurdles are huge, so no way that's going to matter any time soon.
