I'd like to see them explain why AI have so distinctive writing style that is very easy to detect most of the time. Even though, it had immense progress in coding, it didn't get better at writing.
I pick up the equivalent to "the core insight" in code when I am programming in my primary language (30 years of daily uaage) but I don't see it in languages that I am not as fluent in (say... 10 years daily usage).
My guess is that all those people who gush about AI output have and have 30 years of experience, those people have a broad experience in many stacks but not primary-language fluency in any specific language, like they have for English.
