I won't speculate on whether the post is AI-written or whether the author has adopted quirks from LLM outputs into their own way of writing because it doesn't really matter. Something about this "feeling" in the writing causes me discomfort, and I don't even really know why. It's almost like a tightness in my jaw or a slight ache in my molars.
Every time I read something like, "Not as an aesthetic choice. Not as nostalgia. *But as a thinking tool*" in an article I had until then taken on faith was produced in the voice of a human being feels like a let down. Maybe it's just the sense that I believed I was connecting with another person, albeit indirectly, and then I feel the loss of that. But that's not entirely convincing, because I genuinely found the points this article was making interesting, and no doubt they came originally from the author's mind.
Since this is happening more and more, I'd be interested to hear what others' experiences with encountering LLM-seeming blog posts (especially of inherently interesting underlying content) has been like.
It's been my experience that westerners (I am a westerner) do have different assumptions about "mainland" Chinese people than people from Hong Kong who are assumed to be more cosmopolitan, "westernized", or even "politically neutral" from a western liberal capitalist perspective, so it seems reasonable to point it out in this context.
