It calls into question Spacex's low cost thesis. If Musk is fundamentally wrong about making rockets, is he right about making money selling lots of model 3?
I had a engineer relative recruited and employed by SpaceX in 2015 for his particular manufacturing skills. There is not the slightest chance that anyone who knows him would be willing to ride on a spacex rocket into space. The disorganization, as well as the ad-hoc engineering decisions made by non-engineers, is completely unacceptable. Spacex was recognizing these deficiencies in 2015, and hopefully this situation is improving. But it is hard to improve without a stable base of talented employees.
If Musk can't hire and retain the right talent, and let those people make decisions without his frequent interference, there is no chance that Tesla will become a large manufacturer. It is all connected. A rocket exploding is just more dramatic than dive unit replacement on a model S.
