By the end of that paragraph thereafter I started skimming as the rest turned blatantly LLM.
I should have caught the emdash in the first code block in "Who else is calling" though...
You didn't stop reading after "The hack itself is on its way out, but the design behind it still matters for your code"? I did.
I have a suspicion that in these cases, either people are purposefully copyediting only the very beginning, or the very beginning has most of the prompt and the rest is pure extension.
