If I had a cent for every time I see a HN semi-regular (i.e. not a throwaway account) falling for some rather transparent bullshit, I'd enjoy my retirement on a significant "FU money" cache... Everyone gets duped sometimes, often publicly.

I remember skimming a summary of the story itself. Sounded like textbook failure mode of reinforcement learning. I was actually saddened to later learn it apparently was just a thought experiment, and not a simulated exercise - for a moment I hoped for a more visceral anecdote about a ML model finding an unusual solution after being trained too hard, rather than my go-to "AI beating a game in record time by finding and exploiting timing bugs" kind of stories.
