Earlier quoted context omitted.
It was never above page 4 (position 90): https://hnrankings.info/41651548/ This version of the thread is the first to have had any traction on the front page. When the algorithm artificially stops a topic from surfacing to the front page, the article that finally makes it past the algorithm's suppression is not a duplicate, it's the canonical copy.
So what if it didn't make the front page. That doesn't mean ppl didn't see it. Doesn't mean ppl aren't commenting on it. Maybe it's just not that interesting. There was also a lot of other big news at the same time with Meta etc taking attention. And followed by the other OpenAI news with Mira. Again, the discussion is there.
I'm pretty sure that what happened is that the Murati thread was id'd by the algorithm as the canonical OpenAI discussion, artificially suppressing the more interesting topic of the complete restructuring of the most important company in existence today.
