The author is right about how dangerous it is for students to only learn from one source though. However, how is this different someone who gets all their news from Fox? Each person has their internal bias, and will learn from their chosen source. Existing education system, ranging from school texts right down to the career path is dictated by academia. I can't see a better alternative other than simple freedom for people to chose who they wish to learn from, and how they wish to lead their lives.
