I wanted to laugh at and belittle openai when I first saw scarjos claim that her friends and family couldn't tell the difference but from the samples you just linked I find that so unlikely that I think she is lying.
The other reason is that in cases where a comment didn't deserve to be downvoted (which you're right, was the case here), fair-minded users will usually come along and give the post a corrective upvote (https://hn.algolia.com/?dateRange=all&page=0&prefix=true&sor...). Which fixes the problem except then comments like your reply here linger on as inaccurate—there's no garbage collector to take care of them.
You post like that (short grump) just about every time and you shouldn't.

They both have a vocal fry, but the former sounds more like valley girl without the slang or vowel lengthening.
Copying a comment from another HN user (not sure if appropriate to name them):

That seems like quite a strong resemblance to me.
