This comments illustrates the article, which has nothing to do with "fake it till you make it", and is all about how people often think they know something, when, in fact, they have little knowledge on the subject (in this case, the subject being the article in question).
To clarify: "fake it till you make it" is pretending you know something when you know you don't, the exact opposite of what the article is about (not knowing that you really don't know something, and being confident that you do).
Not to knock the OP (hey, we all go straight into the comments from time to time) :)
