Be careful with this, you'll get burned sooner or later. Short sentences and breaking up the rhythm are often taught as good writing style. The people will also pick up some LLMisms, especially the non-native speakers. I enjoyed this prose, I felt like author had a very personal perspective to share. My AI BS detector didn't spike and I think your post is the over-confident one.
Maybe you don't interact enough with Claude? "Underneath it, three slower clocks are running, and they set the terms on which we meet the next shock.", "A gauge reading is a level against a reference mark, not the depth of the river.", "Two official statements frame everything below.", "where a number rests on a vendor, an advocacy group or an industry estimate, the text says so" were not written by a human.
No, this is 100% written by Claude. It reads exactly like it, with all of the same phrasing, awkward sentence construction and other annoyances I have to deal with all day long.
