Just reading the first few comments.... I really don't get the Tesla hate. Is it hacker-ish contrarianism? Have they done something? What's the deal HN, why are we cheering against the home team? Overall Musk has been pretty straightforward and explicit with what he's doing. Tesla (and spacex) set extremely ambitious goals, like none of their competitors do. They take big risks. They're not interested in reducing ris…
As to SpaceX--it's an extremely interesting attempt to tread a well-worn path. Commercial exploitation of space travel is a really neat concept. But again your comparison is completely unmoored from reality. SpaceX disappearing will "hurt our changes of landing people on other worlds anytime soon?" Who exactly do you think got us into space, then to the moon? Who is responsible for almost all the progress in space exploration to date, including developing the RP-1 based rocket designs that SpaceX is refining half a century later? It was U.S. defense contractors! It's worth keeping in mind that the Saturn V developed by Boeing/NAA/Douglas in the 1960s could hurl three times as much weight to the moon as the Falcon Heavy. To date, the only proven model for treading new ground in space is large defense contractors spending gobs of State money.
The real question is: why does Tesla/SpaceX generate so much sophomoric positivity?
