Pointing out errors is constructive as it makes us less wrong.
I love comments like this because it saves from wasting time reading the article. it is the reason I check the comments before reading the article. That's valuable to me.
What is the counterpoint to pure fluff? It's enough to call it like it is and move on.
I normally do when I comment on HN. But honestly there's nothing to "counter" because like I said there's no substance to the article. I could criticize all the little details but that also doesn't feel right. It would be like a professor trying to grade a student's report and having no idea where to start because it's just a long rambling about nothing and has nothing to do with the suggested topic. In these cases they will just say "Rewrite".
It needs more than a rewrite. The author has misspelled Entrpreneurship (sic) in the title itself. I usually try to look past typos, but that one (and the others sprinkled throughout) make it difficult for me to take it seriously.
If the only valid way to reject an erroneous mathematical theorem was to offer a valid one to replace it, mathematics today probably would be stuck in an unnavigable quagmire of he-said she-said.
Fortunately, mathematicians managed to reject the rhetorical approach to truth-finding. Will the rest of us follow?
HN threads are casual conversation, which is as far from mathematics as you can get.
