Wow, very powerful stuff. This article rapidly expands from indictment Noam Chomsky as linguist to indictment of modern academia. As a parent about to pay large sums to one of these institutions for my son's education, it depresses me more than a little.
I don't know anything about linguistics, but the argument hangs together pretty well. It's consonant with what I know about Chomsky as political prophet and myth-maker.
I notice that this article, a decade old, also indicts science in general. The author was perhaps ahead of his time:
