The Khan Academy is a conscious attempt to bypass the monopoly of information that liberal academics currently hold.
There are no examinations and no certificates. These are actually products of the old order. In the future we will be judged by what we can do rather than pieces of paper issued by authority. Anyone may study these materials. There is no one to tell you that you cannot understand them and so you must do another course first. There is no one to tell you that your values are unacceptable or that you are too male, pale or stale.
The Khan Academy gives you access to information without political correctness, student unions or Marxist lecturers. It is the future and rioting rich kid 'revolutionarys' are the past.
May they rest in peace.
