Sophistry and the “education” meme

A degree is not an education

The entirety of human knowledge is available on the internet, and it is possible to educate oneself in hitherto “hard and difficult” fields. There are even multiple presentations of the same material at varying levels of complexity and viewpoints.

So what is the use of schools and universities, beyond basic literacy and use of laboratory type facilities?

I am not the first to ask this question, but the answer is especially relevant in light of the education bubble. What is the use of increasingly ineffective teaching protocols and more teachers, when the option is better and much cheaper.
