This article starts by claiming developers have only a superficial knowledge of the languages they use, and on that basis, it argues we should teach languages in a more superficial way. But it's unclear what benefit we'd supposedly reap by teaching languages in a more superficial way? If there is a substantive point to this article (aside from the pretentious suggestion has a deeper knowledge of programming than everyone else), I failed to understand his point.
