I don't see any such "math gate" on this link. Also, this math does have practical applications, but they're not mentioned until very late in the article.

My suggestion is that briefly mentioning them up front might be nice. I didn't mean to start a big argument about it.

i'll never fathom why people on hn treat a post as an auto-invite for unsolicited feedback.
