There's nothing AI about that sentence.
Also we have reached the point where LLMs are pubkishing more contents than humans so we have probably reached a point where humans will inconciously start copying and using LLMs style too.
1) negative parallelism: "It's not bold. It's backwards."
2) em-dash addiction: "The problem -- and this is the part nobody talks about -- is systemic."
again, i'm not saying the author wrote this sentence using AI. i was just tickled by how stereotypically AI it sounded. for better or for worse, those characteristics are just going to set off the AI detector in people's heads now, as evidenced by the fact that there are like 10 separate comments on this post that picked up on the exact same thing.
