It's ok to not like the guy at the top, but still marvel at the achievements of the people he pays.
I agree that plenty of good has happened because of the profit motive but SpaceX is not patronizing the sciences, NASA is.
I appreciate their work however and it's a shame that Musk has tainted their efforts. He could be a decent man if he tried but he's clearly chosen a different path.
You see the same sort of thing in F1 drivers. Even in the most casual of driving competitions they are competetive to the point of pettiness. My theory is that's part of what makes them an F1 driver - the inability to lose. it can easily be turned to destructive purposes, see all the avoidable crashes but it gets harnessed and turned to useful purposes.
On a more loaded tangent, see Trump. His lifelong ambition was to be famous and become president and i thinkthat, more then his billions gave him the drive to run for office and get reelected (you can argue that it was to satisfy his overwhelming ego but that doesn't change my point). Even if you despise them and everything they stand for i think everyone can learn something from them in how to succeed in their goals. it's not being narcisstic and elbowing everyone out of the way, but it is about having goals, wanting them enough and a healthy dose of self belief.
And if you actually study SpaceX and Tesla, then you figure out that they are actually very smart with their capital investments, and therefore didn't need nearly as much funding as his competitors.
And not being able to do one thing, running twitter, doesn't mean magically that its the same at other companies. Morris Chang failed at running a consumer facing job at TI but do we therefore conclude that he is bad?
