Elon Musk on the creation of Tesla Motors, PayPal, SolarCity and SpaceX and his future projects.

In this video, TED curator Chris Anderson talks with Elon Musk, the creator of companies like Tesla Motors, PayPal, SolarCity and SpaceX, about how he came to create his projects and his plans for the future.

Remember the proverb that some people make the world go, while others run alongside and shout about where the world is going?
