The signal to noise ratio is so bad that addressing the problem head on seems like a valid solution. Is it the best solution? Maybe, maybe not, but I disagree that mentioning an acute problem is a self-awareness-less action. I doubt most readers are able to truly tell just how bad these comments are so I'm doing some sort of service to some people by calling it out.

Let me give an example for myself. I am not an expert in ML. I come to HN to learn about ML and I feel like I learn a good amount. I try to grok the comments, read the articles, etc. If I stumbled upon a bunch of very, very misguided comments I'd expect or hope that someone would say something so I could save myself some time. I see that kind of behavior a lot when users on HN call out "bad physics" but no one calls out bad aerospace.
