Almost everything in top/new/best is an interesting read. Either I don't know anything about the topic ("...the spanning tree protocol") or am seriously interested in the topic ("Remembering Hong Kong", "Automattic's board forces CEO..."). None of these made to frontpage over the last two days AFAIK.
That out of the way, The admin/moderators can hardly be unware given they work for a startup accelerator that is heavily in on the AI stuff, it is the way it is because that is the way they want it to be.
HN is great but it's bias has always skewed to what is hot in the VC market or that they are heavily in on at the time (as someone who was around when it seemed like every other post was blockchain/crypto it's not even "new").
You can't serve humanity and the machine, you have to choose a master. YC has no choice but to choose the machine because that's where the money is, so HN has no choice but to follow suit. Hacker News is an AI forum.
I'm not suggesting there is some kind of conspiracy afoot but I wouldn't be surprised if they decided to just give in let nature take its course.
