From Fast Company's interview with Udacity CEO Sebastian Thrun; emphasis mine:

Thrun's 5-year-old son, Jasper, is not yet old enough to be impressed by his father's work, but he's already starting his education. "In my son's kindergarten, they're telling us how to get him into Stanford," he says. "By their advice, I'm doing everything wrong, because I'm trying to make him happy rather than putting him through as many piano lessons as possible." He dreams that his son will take a less conventional view of education. "I hope he can hit the workforce relatively early and engage in lifelong education," Thrun says. "I wish to do away with the idea of spending one big chunk of time learning."
