> I'm not sure you realize this, but your comment is exactly why colonizing Mars is a worthy adversary. It requires doing things far beyond our knowhow, which historically is the best way to actually get something done – inspire towards an impossible goal and humanity can make it happen. You can say the same thing about literally any other hard problem, most of which have a far better ROI, and are still not getting much traction. There's a reason nobody's built a moon base.
