The update itself has strong AI tells:

> I do write like this sometimes. The short sentences, the reversals, the one-word lines—all of it. It’s just the way it is.

> That says something about my writing. It says nothing about who wrote it.

> So let me be plain about it: Claude was not here. No LLM wrote this—not a sentence of it, nor was it outlined, drafted, reviewed, checked, etc. by one

Either the author is doing this on purpose, or this is some kind of art project. I don’t buy the “just a coincidence” story at all.
