Arrgh. I can't believe I missed that.

To be fair though: it's quite clear that all the discussion in that post is commenting on the headline and not the content. Bland self-improvement "life hacks" are one of the metaphorical crack pipes of this site. We all have way too much to say on the subject of our own productivity.

So I think it's less likely that HN was fooled by GPT-3 but that GPT-3 was good enough at filling a plausible article out around a tempting headline.
