There are a bunch but in my opinion not conclusive.

It's loaded with it to my eyes. (Pangram also agrees and flags the whole post as AI generated.)

  # 2014: rqlite
  The need was concrete.

  # Before 2014, and alongside it
  Two things deserve mention for honesty’s sake.

(the above line is extremely typical of Claude Opus 4.8 and 5.0)

  [...] and the main difference is of one of packaging:

  # What the twelve years show
  Three things, I think.
  The core was right. [...] Nobody has found a reason to stop doing it.
  The design space has three corners, and they appeared in order.

(What order? The corners of this design space, which aren't spelled out until the following sentence, don't have any other natural ordering. This type of misapplied flourish feels very typical of LLMs.)

I envy you. For better or worse, Claude is the author I've read the most in this year. There's a handful of human authors I know well enough so that I would recognize a text that was written by them. With LLMs, it's much easier than with humans, since the current generation of LLMs seems utterly incapable of changing their style.

If you talk to Claude all day every day like some of us are forced to, it's plain as day.
