I linked to the response sections instead of the paper because the paper is boring.
I don't get what's with folks getting stuff related to covid very wrong—which is fine! Practically everyone was wrong about it at one point or another!—but then doubling down on their position when it's crystal clear they were wrong, instead of owning up to it and moving on. They do it to the point of completely wrecking their reputations and making having-been-wrong-about-covid-but-being-in-denial their entire public persona, as in this case. Why? Why do that?
The bit where he was insulting the appearance of a grad student, at length, in a goddamn peer reviewed paper—I mean, damn dude, how do you not realize you're fucking up when you start heading down that path? What must be going wrong with someone for them to look back at that writing and go, "yep, nailed it, time to submit, this is definitely gonna convince people"?
