[[citation needed]]<p>I am a professional writer and have been for over 30 years. (I do not use any form of LLM ever.) This means I read <i>a lot</i>. This also means that I have 30+ years of experience of readers not understanding what I wrote, or not getting further than the title, or not getting the main message, or inverting it in their heads, or inserting their own message and then complaining when I diverge, and an endless list of Ways People Do Not Get It.<p>I am also a trained TESOL teacher. Ability to capture gist is a skill we test for and measure, and many, maybe the majority, of native speakers don't have it and don't know.<p>In recent years I <i>constantly</i> see people going "this is written by AI" and I have yet to see <i>a single of of them</i> able to coherently prove their point. It's all just feelings and hunches.<p>So I am calling you on this:<p>How do you know? Show your working. Demonstrate your case.
