I think it would be easier for all of us to understand if you elaborated on what you think the issues are. What concrete things are you missing from ExUnit and documentation, what do you wish was different?
You can ask ChatGPT or any major model: from the perspective of an expert technical writer/information architect, how would it evaluate the Elixir documentation, and it will surface key issues.
I don't care what a sycophantic machine "thinks" because I can get any answer I want out of it by subtly changing the phrasing of the question. I thought you had legitimate points to discuss in good faith, not this nonsense.

Not only this article dumps significant cognitive load on the reader. It's not well digested and not a soft landing into the subject. Worst of all, many Elixir articles assume familiarity with GenStage.
