I wish you had read my original comment, where, let me repeat it a second time for you, I state that the author writes about how to approximate a 'function in the laymen sense of the word'. And that's what he does. Nowhere does he bring hype into it; no one reading about how to approximate a simple y=f(x) will misread this. My guess is that you read the website like you read my comment, if at all, otherwise we wouldn't be having this ridiculous conversation. renewiltord's comment is spot on and much better phrased than I could have done it.
