That's how life generally works. If your friend tells you, "I went to that new movie yesterday. It was very boring, I fell asleep midway." - then you either listen to his advice or don't. You don't ask your friend if they ever made a movie of their own.. And you don't ask for a 3rd party research of that movie's either.
As for AI specifically.. life is too short to read all the interesting pages already, and AI just makes is so much worse.
- AI is verbose in general, so you are spending a lot of time reading and not getting much new facts out of that.
- Heavy AI use often means that author has little idea about the topic themselves, and thus cannot engage in comments. Since discussion with authors are often most interesting part of HN, that makes submission less interesting.
And yes, it is possible to use AI assistance to create nice and concise report on the topics you can happily talk about, but then this would not be labeled as "AI".
