As a physicist I have a similar reaction to a bunch of topics. Sometimes people are very happy with the insider info I can bring to a thread (e.g. how does the EHT create it's picture), but sometimes you get so much opposition from people who obviously don't have a clue and simply assume that everything is simple to solve with machine learning and that all professional scientists are bumbling idiot who can be save by the comments of a silicon valley kid that it stops being fun.
I wonder if a "badge" system could help HN. Validate professional work experience with a moderation team ("astrophysicist" because I have published papers there, or "radiation control tech" or "worked in the movie industrie" or "work at google" or whatever). You could even have more than one badge (say "work at google" and "race sailboats for sport"). And when you post a comment there is a list of all your badges below the text field an you can select one to be displayed noticeable above your comment to indicate "I have professional knowledge of this". Of course you can still post a comment without selecting any of your badges because "radiation controll tech" says nothing when discussing cookie recipes, but is an important thing to not when discussing a radioactive spill.
