The replacement of emdashes with double hyphens here is almost insulting. A look through the blog history suggests that the author has no issue writing in English normally, and nothing seems really off about the actual findings here (or even the speculation about causes etc.), so I really can't understand the motivation for LLM-generated prose. (The author's usual writing style appears to have some arguable LLM-isms, but they make a lot more sense in context and of course those patterns had to come from somewhere. The overall effect is quite different.)

Edit: it's strange to get downvoted while also getting replies that agree with me and don't seem to object.

(Also, I thought it wasn't supposed to be possible to edit after getting a reply?)
