After reading this and "the everything store," I wonder what Jeff Bezos & Blue Origin (which started in 2000) would feel about Elon's recent endeavors with SpaceX (started in 2002), considering his highly competitive character.
They are not competitors. I don't know what Bezos said about it, but Elon Musk said:
"Every time I see Jeff, I ask him why he's not doing more in space."
"Our [SpaceX] competitors are not Paul Allen and Richard Branson, but Boeing, Lockheed, and the big aerospace companies. I'm really glad to see all the activity in entrepreneurial space and hopefully this heralds a new era of space exploration with price and quality improvements similar to other technology arenas."
Note that they're going to be competing a little more in the future. It was announced a couple of weeks ago that Blue Origin will be supplying engines to ULA (the joint venture of LockMart and Boeing that operates the Atlas V and Delta IV rockets).
