I hear you. I actually thought about this when making the comment, but decided to make it because the website at hand, gwern, is also deeply interested in AI and GPT and has a lot of posts about it.
It does feel a bit like the mid 2010s when everyone was talking about applying blockchain to everything. The difference, I think, is that the proof is in the pudding. I have browser plugins and HTML5 physics simulators now that I didn't have just months ago.
Re: your particular issue, I am not joking, you should use ChatGPT to help you write a browser plugin that simply blocks those comments. The browser plugin I mentioned that I used GPT to create is actually for blocking low-effort HN comments. My HN browsing experience is much better because of it.
