People might've mistaken it for pedantry/condescension? I certainly didn't take it that way (gave it an upvote) -- though I have read that paper, and was thinking of it when I wrote my original comment :)

It was not my intention to be condescending. I legitimately enjoyed that paper (the technical part mostly), and thought it was relevant to what you were saying. I've found a lot of many interesting articles in hackernews comments and wanted to share one back.
