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.

When he wasn't programming or doing schoolwork, D'Aloisio began to fill his spare time reading about natural language processing. He'd studied languages as diverse as Latin and Mandarin, and became fascinated by concepts like grammatical frameworks, morpheme parsing and the 1960s work of the linguist Richard Montague. 'He's my favorite,' D'Aloisio enthuses. 'He theorized that natural language could be described like a syntactical programming language.'

But that hasn't stopped scientists from growing actual human brains in a lab. Starting with nothing but stem cells, scientists in Austria this year managed to create brains equivalent to those in nine-week-old fetuses. These miniature brains are the size of peas and are incapable of thought—so far. The one thing keeping the brains from growing beyond this stage and becoming fully functional is that they have no blood supply.
In 2014, the actress Tilda Swinton wore false teeth in four movies: “The Zero Theorem,” “The Grand Budapest Hotel,” “Only Lovers Left Alive” and “Snowpiercer,” a film directed by Bong Joon-ho.

Closer to home, fake official data are just as prevalent. The UK’s Office for National Statistics on Tuesday reported that British inflation, measured by its longstanding retail prices index, rose to 4.1 per cent in December. This number is nonsense and the ONS knows it. It tells people the RPI “does not meet the required standard” to be given a quality stamp, yet it has refused since 2012 to take steps to improve the measure and bring it closer to the lower headline measure of 3 per cent.
To be fair though, no other country has ever had China’s assets: a stable government with an unequivocal, long-term financial and strategic commitment and a huge domestic—hence mostly captive—market. According to market forecasts, China’s domestic air traffic is expected to almost quadruple between now and 2036 to reach 1.6 billion passengers, which will be more than twice the U.S.’s domestic traffic by 2036.

'Nebraska' gets to the heart of Bruce Dern's prickly old geezer, Woody Grant, by way of a road trip across Montana and Nebraska, shot in radiant black-and-white. (Here again one of the movie's stars is its cinematographer, Phedon Papamichael.) Alexander Payne directed, flawlessly, from Bob Nelson's stellar script, which is all about thwarted love, and reconciliation, between Woody and his son Will; he's played with painfully quiet eloquence by Will Forte. Here's the American heartland as it's seldom portrayed on screen, with humor and almost palpable fondness.

Stock pickers encountered difficulty this year in part because of concentration at the top of the market. Just five stocks—Apple, Berkshire Hathaway, Johnson & Johnson, Microsoft, and Intel— accounted for 20% of the market’s gains. If you weren’t at least equally weighted toward them, you had virtually no shot at making up for missing their enormous, index-driving gains. A majority of the market’s stocks did not perform nearly as well. According to the Leuthold Group, only 30% of S&P 1500 stocks posted gains exceeding the index itself. You’d have to go back to 1999 to see anything like this.
