Space travel will never be profitable because it’s so expensive. We have plenty of minerals here on earth. The only benefit of asteroid mining is using it to build spaceships already in orbit.

If we have enough resources to actually explore other planets, we’ll probably be post-scarcity. There’s not going to be any profitable reason to go to space. It’ll just be to have the experience. There’s nothing special in space, it’s just rocks with no air.
