I'm a university dropout, but the level of linear algebra, multivariable calculus, and discrete math that I did take before leaving school is so far above and beyond what Khan academy currently offers. With the exception of Calculus, Khan academy is up to about where my public high school curriculum left me. Its calculus offerings are impressive and definitely cover my first year calculus courses. I've never been able to make much use of OpenCourseware because it doesn't fit my learning style. Don't get me wrong, I'm not holding anything against Khan academy. But it's quite impressive that it will eventually cover all the material in university that I had to pay to learn. There is a huge collision that's about to happen: increasing costs for post-secondary education; a middle class that will no longer be able to afford said post-secondary education for their kids; and free, quality, ubiquitous educational content like Khan academy. I'm not quite sure how things will play out. But things like Khan academy could pop the educational industry bubble, at best forcing lost cost quality formal education, and at worst, resulting in ubiquitous access to informal education to those that put in the effort.
