I find that a lot of folks who are in positions like Musk, who are innovative in ways that others don't really consider, are usually heavily criticized. There have been two CEOs that I've worked with who were both kind of on another level with how they processed things and calculated risk, but their obsession made them successful. Musk is interested in continual improvement, even if the methods are risky.
I dunno, I think that it's interesting to see unfold. Maybe someday we'll have tubes all over the place, who knows! I'm sure 100 years ago they didn't think flight would be commercialized.
