Data without interpretation is irrelevant, and correct numbers can be interpreted wrongly, either on purpose or by mistake.

I’m not saying any of that happened here, only that “are the numbers wrong” is not the only thing that is relevant.

> humans do use em dashes, just FYI.

Your parent comment is not complaining about em dashes, they are pointing out the article has a literal “&emdash;” in it.

Yes, I do for example.

And the author discussed the use of AI pretty exhaustively in point 0 of the post.

But: "After posting this on Hacker News and recieving [sic] almost no substantive input, discussion, or response on the actual content of the article, I decided to rewrite all of the prose in my own voice. If anyone complains about my verbosity or sentence structure — as they usually do, which is the reason I originally let the AI write the prose, among other reasons obsoleted by templating — they can go fuck themselves."

So rewritten in his own voice. Maybe the m-dashes are from GLM, maybe from the author.
