It wasn't a generated comment at all! Read the comment, and then what the author wrote elsewhere saying they spoke it into their phone. https://news.ycombinator.com/item?id=49948614

"To reiterate, those were legit questions. I used voice dictation to my phone, with an app that transcribed and formatted my message."
