I just stumbled across a wonderful exchange between Sal Khan and Elon Musk. At the 35 minute mark in the video above:
Elon Musk: "It seems like you are doing an amazing job of leveraging a small team for dramatic effect. [cross talk] It's a very impressive thing you are doing to spread knowledge and understanding throughout the world."
Sal Khan: "The universe, soon, if you hold up your end of the bargain."
It's fun to think about what the future will be like if they hold up both of their ends of this bargain.
