In short yes. I had that same thought too. But I also know that there is a lot that I don't know. SpaceX has done some incredible engineering and what they're doing is hard and unforgiving. Another great aerospace engineer - Burt Rutan - complained a while back that as long as people aren't dying we're not pushing hard enough. To some degree I think he was right. Let's just be happy that SpaceX IS pushing hard and has learned these tough lessons without harming any people so far.
