Or to put it another way, we live in a relatively normal time, when a product used by a double digit percentage of every living human on the planet is worth more than a high capital expense gov't contractor.

I love space, I love SpaceX in particular. That doesn't mean I think this valuation is out of whack. Facebook and Whatsapp have literally unprecedented reach. It's easy to hand wave off as 'just a messaging app', or 'just a social network', but we're talking about brands that achieved the global reach of Coca Cola in under 10 years. That's nothing to sneeze at.

Meanwhile, SpaceX is making something roughly as technically difficult as stuff Boeing, Lockheed, General Dynamics are all doing. Should those companies be worth more?
