Eh, somewhat. There are definitely more articles and projects created by AI tools nowadays, and those just feel uninteresting to me.
But at the same time, I have to question whether I'd feel the same way about any other era of Hacker News. Like on Reddit, a small percentage of submissions will interest me on any given day. However, that doesn't necessarily mean the others are bad, they're just not for me.
I do have to wonder if you're mostly just noticing that the majority of content here simply won't be something you're interested in, just like in any other community.
