First, a lovely update from Aarti. Then, Sal Khan, a man who challenged the education model we’ve been using for centuries. In so doing, he created the largest school in existence. Khan tells Art of Power host Aarti Shahani about the humble origins of Khan Academy, how he wanted to offer a world class education — like a Harvard or an Oxford — except online and free for everyone, and how he had the confidence to revolutionize education.
