I didn't downvote you but you make a lot of patently false claims, which at best show you're ignorant of what SpaceX is doing. As others have said: - You say "some domains don't lend themselves to rapid prototyping" - yet SpaceX's results speak for itself - You say "unusually prone to safety incidents" - can you list 5 of them so that we know what you're talking about? "testing incident where a fuel tank exploded" - that's literally their designed operating mode, nobody was put in harm's way, you're basically disagreeing with how they operate (should have the humbleness to consider that their impressive results so far might indicate they're right and you're wrong) - You say "they can't even take a rocket out safely, how are they hoping to achieve anything" just after even their competitors praised them for the impressive results. etc. Is it really surprising that you get downvoted?
