The headings style wasn't an immediate giveaway to you? The rules of three in every. short. staccato. paragraph? The X, not Y?

The author's writing is wildly different pre-AI.

For me it was "There’s a clean exception to all of this, and it flips the entire logic." and "here’s the reframe". That's Claude-speak.

You could say it flipped their entire logic. Not that it would make sense. But I groaned reading it.

I reckon the article was edited so I saw a different version. I noticed the HN title and current title differ.
