What I find problematic about all of these new online education startups (Udacity, Khan Academy, etc) is that they tackle the problem by simply providing online equivalents to traditional didactic learning methods like lectures and textbooks.<p>A professor standing in front of a group of students lecturing is definitely easy for the professor and cost-efficient to scale up to larger class sizes, but that's just not how a lot of students learn. I'd wager that most HNers learned programming through actually writing code, even those who learned CS through a formal program. In the humanities, I'd argue that the most effective way to learn is through small discussion groups, not a distinguished professor explaining literature or philosophical works to you. Just throwing that up on the internet is an easy way to expand your audience, but providing higher-quality educational materials doesn't do anything to improve the quality of <i>how</i> we educate.<p>The internet has a lot of potential to improve the quality of education, and there are tons of awesome startups working on it (companies like Codecademy and Coursekit come to mind), but I personally hope the future of online education doesn't look too much like Udacity.
