I also love how fast SpaceX iterates but it does come at a cost. If one design fails, they can quickly iterate to a different design that works. But sometimes that means they aren’t investigating the science behind the failure. Great from an operational engineering perspective but less good from a fundamental science perspective. To their credit, I don’t think the latter is their main role.

Regarding the cost, the aerospace industry needs some scrappy young start ups. However, quality pedigree is a large chunk of the cost of flight and SpaceX has shown some gaps in the past. I think a big question is whether they can keep that scrappy startup up culture while also building processes robust enough to meet space flight quality standards
