HN was 10x more political 15 years ago.
Less party partisan stuff being sneaked in then (I think it's the parties themselves sometimes doing it now), but more meaningful discussions on politics, especially/primarily having to do with how they crossed with tech.
But everything crosses over with tech: finance, the current state of the market, importing and exporting, taxes, surveillance, censorship, encryption, copyright, patents, freedom to tinker, wars, weapons, government contracting, military contracting, corporate structure, etc. etc.
There wasn't this random immigration outrage bait pointing out 1 of the 80 people in a particular month who were shot by law enforcement for no good reason, but there was plenty about immigration because techies are immigrants and hire immigrants, and outsourcing, and working with a remote team in the middle of the night, etc. etc.
The only thing that was absolutely deemed "politics" and excluded eventually was discussions of women and black people in tech.
AI is just the new Rust, is the new X in javascript, is the new concurrency/Erlang, and so on. All of those things are still important; none of them went away or are going away.
I think heavy moderation serves to keep some variety, and to simply throw away the 9000th iteration of the same thread that never goes anywhere. AI stories aren't bad; it's the same AI stories, again, that are bad.
