Reclaiming The American Dream VI: The (Other) Lessons of Khan Academy

Howard Husock
This article is more than 6 years old.

To say that Khan Academy has important lessons to offer is to state the obvious. The Mountain View-based internet teaching institution—which has grown from founder Salman Khan’s individualized YouTube math lessons for his 7th grade niece to a worldwide phenomenon—offers thousands of free, plain-spoken online courses, from algebra to biology. But there are even broader lessons to be taken from the astounding success of Sal Khan, winner of the Manhattan Institute’s $100,000 2014 William E. Simon Prize for Lifetime Achievement in Social Entrepreneurship. Indeed, the lessons extend well beyond education

The story of Khan Academy’s start and growth is dramatic. Sal Khan, New Orleans-born and MIT-educated, was working in the finance industry as a hedge fund analyst when, in 2004, he learned that his niece, Nadia, needed help with algebra. He began sending her his own clear, step-by-step illustrated lectures (Khan himself did not appear) via YouTube. That allowed other web users to use the same lessons. The teaching of Khan—a complete outsider to education or education reform—went viral, ultimately catching the eye of Bill Gates, whom Khan learned was helping his own children with lessons first meant for Nadia. Khan eventually attracted $15 million-plus in philanthropic support from the Bill and Melinda Gates Foundation, Google , venture capitalist John Doerr, and others accustomed to the idea that radical newcomers might be worth investing in. Such funding allowed Khan to give up his day job and start Khan Academy, with a forthright, undeniably ambitious goal: a free world-class education, for anyone, anywhere.

For starters, breaches like that of Bitstamp and the much larger (valued at about $400 million at the time) 2011 hack of the exchange Mt. Gox are often misconstrued as security issues with the currency itself. But they are only signs of flaws in those particular exchanges and not a sign of an issue with the underlying technology. And it is the underlying technology behind bitcoin that most excites. As we wrote in the “Shape the Future” package of our January 2015 issue, most of the vocal enthusiasts so bullish on bitcoin—from big-name entrepreneurs like Marc Andreessen to the developers and miners who spend their days refreshing the bitcoin Reddit page—are more interested in the applications that can be built on bitcoin’s “block chain,” the currency’s foundational backbone, than they are in bitcoin as a monetary system. The block chain allows the secure exchange of any form of value between two entities.
