My second response was sassier than it should have been. Sorry for that. I'm not making any claims about whether or not GPT implemented this. My point was narrower in a way that is probably annoying: you asked why you were being downvoted; I tried to explain that, as far as I could tell, the adaptive system you explicitly described (regardless of what adaptive reasoning actually is), where
humans choose the reasoning level, isn't the one that the paper proposes -- and that this may be one of the reasons for the downvotes.
I don't know whether that's why anybody downvoted you, but I think that's probably part of the reason. On the other hand, the Hacker News guidelines ask us to respond to the strongest interpretation of a comment or post. In that spirit, just as you could have said something to the effect of "Yep, AI researchers learned from behavioral economics and research into human decision making and here's where OpenAI mentions it," I could have said just "the relevance may not be that it's a new idea but rather that it's a neat idea, to the person posting it at least. Maybe someone who knows AI systems more deeply wouldn't find it interesting. I do though!" That's a bit of hypocrisy on my part, I think.
Anyhow, for the record, yep, I knew of adaptive reasoning, but, no, I didn't know that it matched what this paper proposes so closely. Thanks for the correction!
