I think that the combination of brash, innovative SpaceX and solid, competent and experienced Boeing will be an excellent one. Elon Musk has made it very clear that his goal is to build a city (not research facility, or colony; "city") on Mars soon enough for him to retire on, with or without help from NASA. Boeing is looking to corner the market on cheap, safe and utterly routine spaceflight; to do for spaceflight what they've already done for commercial jet air travel. In their own ways, each goal is incredibly ambitious, and fully achievable with the teams involved. I'm really, really happy to see these two moving forward in realizing commercial spaceflight.
