How does Pangram detect this? How do we know this is any more reliable than just asking any HN user to judge a text for AI signs, i.e. how is this more authoritative than the comments you're responding to?
We don't. Pangram is HN's astrology. It has 99.99% accuracy (according to Pangram.)
"Detect AI-generated content with 99.98% accuracy." -pangram themselves
But there isn't and won't be such a tool. As a fallback people defend Pangram etc. Posting Pangram scores in comments is fundamentally no difference than posting ChatGPT responses in comments, and it's quite hilarious that the former is normalized on HN.
