“The author doesn’t understand the material” isn’t an ad hominem — most of my work involves working with other people, usually less experienced, to help them deliver reasonably complex econometric or ML models. Sometimes I’m hands on, usually not. Knowing if it’s “the author not understanding the material” is important because my job is to help them understand it so that they can deliver something that 1) works and 2) does what it’s supposed to. AI written docs are at best a mixed blessing.

Or maybe it’s me not understanding! Either way, if something looks wrong, I want to discuss it with people who know the subject matter and can talk me through the parts that look off so that I can learn from it.
