I addressed Hyperloop elsewhere, but RE Mars:

> It wold have held more water, if they said it after making real tech breakthroughs

Going to Mars is literally the only reason they're in the rocket business. Like everything behind their breakthroughs, which they had a few - including landing and turnaround times - is meant to enable the Mars mission. They've been explicit about this since day one.

> stunts like landing a rockets

This is not a stunt. It's the real, practical, working, cost-effective rocket reusability. For the first time ever. Not sure what do you expect; em-drive? Because SpaceX booster landing is exactly how a technological breakthrough looks like (as opposed to fundamental science breakthrough).
