I don't know about Claude specifically, but I think people are starting to internalize a sense of when prose reads as having "AI-smell" and I do agree phrases like "Same driver, same track. The LLM is the star." trigger it for me too. That said, that doesn't mean a ton about the whole thing - could be anything from humans starting to echo AI style to someone writing "give my results a headline summary" to an AI to someone saying "here's the data, write an article."
