This is an incredible laboratory of process and methodology: compare "design -> build" to "iterate as fast as possible". While software spent a few decades slaved to traditional engineering approach (building a bridge), R&D like this, even in hardware, has proven to do well at incremental development approaches. We had a few hints of this with how Apple produces things...but it never leaked out into the rest of the world until SpaceX literally started building a spaceship factory out in the open.
