This is why I left this site. Endless smug engineers explaining condescendingly to physicists why they’re stupid sheep, without knowing the first thing about anything. Intellectual curiosity, my ass. Do you have a reply to my concrete criticism or not?

You don't have a concrete criticism. You just have a complaint. Either the math in the paper is right, or it's wrong. If it's wrong, say where. If you can't find anything wrong, say that.
