Sometimes -- and I'd argue often -- leadership consists more of both 1) getting out of the way of and 2) enabling those who Want To Get Shit Done.
I find the fanboiism somewhat tedious (I don't find the top comment of this thread all that insightful), but I do admire Musk for seeming to hit a number of remarkable goals. That said, I find Tesla and Solar City more impressive/promising than SpaceX (technical challenges and accomplishments notwithstanding) or the Hyperloop (ultimately an idea that's been rightfully junked in the past).
Given the history of US industry of doing just the opposite -- stalling and preventing needed innovation -- if I had to pick a single attribute of his that I find most encouraging it's his leadership in that regard.
Without SpaceX it's likely the business would have muddled along without putting any effort into reducing costs for decades.
The way I see it Elon is rising up to those around him not the other way around.
