Musk isn't the only one. He's the one who got the furthest, and who has the grandest master plan. But don't forget about Bezos and Branson and their space ventures.

So, I don't think we're pinning our hopes on one man. But my answer reveals something else. We're still pinning our hopes on Great Men (as in the Great Man theory of history). Musk, Bezos and Branson aren't geniuses in the sense that they are sciencing and engineering all this stuff when nobody else could, they're just hiring the people who do.

Still, I think people fawning over Musk is awesome, because it means people are pinning their hopes on research, engineering and entrepreneurship, because that's what he symbolizes. And hustling the money and funneling it in the right direction isn't nothing either.

It's far better than people admiring people who literally don't contribute anything, or are contributing negatively, to furthering the knowledge and power of the human race, like David Avocado Wolfe, Dr. Oz or Gwyneth Paltrow.

Ok, so we're not at the mercy at a single man, but we are at the mercy of three men? No. Don't forget about China and India, and old spacer-travelers Japan and ESA, and even Russia! They're also further into space than Bezos or Branson, and on some axes further than Musk.

I'm not overly worried. Humanity will get our eggs in a second basket before the century is over.
