Pity that HN's ability to detect sarcasm is as robust as that of a sentiment analysis model using keyword-matching.
That’s just the internet. Detecting sarcasm requires a lot of context external to the content of any text. In person some of that is mitigated by intonation, facial expressions, etc. Typically it also requires that the the reader is a native speaker of the language or at least extremely proficient.
The problem is more that it's an LLM-generated comment that's about 20x as long as it needed to be to get the point across.
