Sal Khan is something of a unicorn—a hedge fund manager who became and educator. Then again, considering what this country pays teachers, that’s probably the way everyone should do it. Khan began tutoring his cousin Nadia in math back in 2004 and decided to turn those lessons into educational videos that he moved to YouTube in 2006. He called his channel the Khan Academy and devoted himself to it full time in 2009. Last year, this entirely free and universally available educational resource had 155 million registered users globally. Khan is working on combining AI and education and testing different approaches to learning via the Khan Lab School. His efforts continue to profoundly impact the democratization of education.
