Make booster reusable

Eh, they've already reused v2 boosters, and with a soft splashdown of a v3 booster, it seems like this isn't too far off.

Make ship have useful payload

Well, Starship Flight 14 was simultaneously Starlink Group 31-1, so I think that counts in terms of operational payloads.

Make ship reusable

This is the one I'm most worried about. I feel like we'll only have a good sense of this after the first ship catch and they get to inspect a flown ship that hasn't been soaking in seawater for several weeks.

Make everything reliable

I think this will just come with time as they ramp up the cadence, like it did with Falcon 9.

It's okay, you may not get to mars but at least you can fly to Fiji in 20 minutes on starship.
