>This is the standard "engineers other than software are idiots" type HN FUD What? I don't think that has anything to do with it at all, and the distinction between types of engineering seems irrelevant. I think he's pointing out that they're trying to make a profitable business without understanding the necessary costs. Given the nature of startups to overpromise and underdeliver (as that's a common tactic to help raise money), his skepticism seems reasonable to me. I see just as many criticisms of software businesses on this site (actually many more, since there are far more articles about software companies here than hardware companies). I have very little aerospace experience so I do not claim to be an expert, and while like to see people tackling big problems eventually succeed, his points seem salient to me.
