Ben Horowitz says the difference between a great idea and a great company is the entrepreneur: "If you look at Tesla, what you would see is big oil, big auto, big government, were never going to let that happen." "They would kill you. But the reality is, Elon Musk, he's hard to kill. He by himself kind of decarbonized the American auto industry, which is unbelievable in retrospect." "If you listen to the politicians now, they're like 'oh, he didn't build Tesla, he just struck a gold mine and is pulling the gold out, all the people built it.'" "Why didn't all those people build another Tesla? Because there's only one non-fungible, very rare person in that equation who could do that. That's why there's only one SpaceX." @travisk @bhorowitz @eriktorenberg(a16z)
