The AI world moves at a blistering pace. Academic publishing does not. In this particular case the "random dude on HN" is probably six to nine months ahead of the academic publication, not in the sense of being that much smarter but literally just being that much further progressed through time relative to the academic publication pipeline.

Scientists are just random dudes (though some of them have been given a fancy hat by a university, which is a recognised mark of accomplishment).

Oh, HN is not random folks at all.

I wish the quiet folks who speak up from time to time would do it more often - I get to learn so much.

Not knowing is a gift in a way, we get to ask, learn.

Pretending is the disease.

we should give a little more credit to the readership of HN. I'm not sure it's that much lower than the average academic publishing on arxiv.
