From what I understand, SpaceX made real effort to split the company into two operations. One uses the reliable Falcon 9 system launching from Cape Canaveral (and other established launch facilities) to put satellites and astronauts into space. The other operation is Elon Musk's playground in Boca Chica where he tries to build the biggest spaceship ever!

Don't get me wrong, there are some good engineers working at the Boca Chica operation, I've heard the Raptor engine is really good and there's probably some other things they've made there that will be useful for rocketry in general. And who knows, the really smart people may get the biggest rocket ever to actually work someday despite Musk's stupidity.
