Elon agrees with you? Did you two have coffee last week?
OK, fair enough, it wasn't technically "impossible", it's just that no company saw it as economically viable or worth pursuing, that the "math didn't work out". The same with his auto company, it's not like other car companies didn't ALSO have access to the technical knowledge and experts to do what he's done, but for whatever reason haven't. Why with all this expertise has it taken so many years for all these "experts" and "industry leaders" to respond!?
And most of what he's done he's been successful because he's gone a different route than "standard approach" / "industry best practices" because let's face it, as "he's said himself", he's been let down over and over again by those experts you for whatever reason feel the need to defend.
It really sounds like you are some low level person that "no one listens to" and you have a chip on your shoulder against Elon, because you seem overly invested in this idea of "our company" and "we're trying to change the world" and that somehow Elon let you personally down.
