The article as written is entirely consistent with John Cochrane's style. I have been reading him off and on over the years so I think I have a decent baseline for comparison. It doesn't smell of AI to me.

If anything, even the included quotes from Refine don't smell much of typical AI, but maybe I am less discerning there. I did notice the em-dashes though!

We flew past the Turing test so brilliantly that now people have to try to convince interviewers that they're real.

For what it's worth, my AI content blocker blocked the article.

It’s worth nothing, to the point it makes people wonder why you even volunteer that information.

Happens a lot to highly reasonable, well written texts without orthographical errors.

Maybe because it quotes (at length) AI-generated output?
