the "why it matters" subtitle near the end seems very much like claude to me

That falls into the general category of 'authority groping' (yes, I coin my own terms) where a prediction engine without real reasoning, must apply numerous tricks to convey confidence, authority and substance where there may be less or none. Similar to the constant negative-propositions or "not" statement, where usually one to three things that do not apply are articulated, which has the result of credibility accumulation, I suppose, by showing "hey, I am right about not just one thing, but four!" hence the saturated styles we tend to see.

I saw a great video on YouTube by languagejones, and he asks: do we have to tell the difference between an LLM and an idiot?

The writing is just bad. I think this is clear to everyone, so I guess we could stop at that
