If a student has access to a great school, Khan Academy can supercharge it. It should help a well-resourced school, and if you don't have that, then Khan Academy can have even a bigger impact. But I don't see it as replacing the actual schools... we want to empower teachers and fill in the gaps.
The ideal direction is using something like Khan Academy for every student to work at their own pace, to master concepts before moving on, and then the teacher using Khan Academy as a tool so that you can have a room of 20 or 30 kids all working on different things, but you can still kind of administrate that chaos.
The leader of an Earth organization who makes a commitment to history - of humans living on Earth, to begin permanent settlement/occupation of not the moon, but of another planet - this leader will have a legacy for history that will supersede Columbus, Genghis Khan or almost any recognized leader.
In 2007, my life changed forever. I signed on 'Tashan,' a full-on glamorous masala movie, with two of the hottest and fittest actors around: Akshay Kumar and Saif Ali Khan. And me, rising out of the sea like a Bond girl, wearing nothing but a green bikini. I had nightmares of how my love handles would be on display for the whole world to see.
