Eh? I think there was a brief timeframe of Too Much AI Related Crap, but the last few months, the front page feels better to me; HN is still one of my favorite news sources.
The comments - I don't really see any kind of "Reddit"ification (the complaint so common it's in the rules!), but there is an annoying tendency towards baseless conspiracy theories lately that annoys me as a professional RE, especially since with LLMs reverse engineering is easier than ever before. Every story about a product release, a cell phone, or anything related to cryptography is loaded with "XYZ entity did this for ZYX comically evil reason," with absolutely no research, facts, or evidence in that direction. Hell, I think the top-voted comment on the "Claude found the nothing-up-our-sleeve randoms from ECDSA" was "it's still an NSA conspiracy!!!"
HN has gone through several Genre Eras of "weird annoying" comments though (that I can remember, there was a suck-up-to-PG era, a "random NRX/Dark Enlightenment Crap" era, etc.), so I think the Everything Is A Corporate Conspiracy era is just our latest phase.
