incidentally i just made this argument in another forum:

whether a text has substance isn't important to me. what is more important is whether the text reflects the author's thoughts, whether it is original or authentic. an AI-generated text doesn't do that. i want to talk to a real person, not someone enhanced by AI. (let me get this out of the way, that's why i also don't like makeup. apart from special cases or situations, i consider the necessity of makeup to be able to present oneself in public like a mask that hides the real person behind it.)

when i engage with a topic, my engagement is with the person behind the text, not the text itself. if someone writes their texts with AI, then i can no longer recognize the real person behind it. i can no longer see which arguments in the text are important to the author, and what are the author's own opinions.

the purpose of a dialogue with a person is to get to know that person better and to develop a shared understanding of a topic. that's not possible with an AI-generated text. i can neither get to know the person behind it, nor can i see how their understanding develops. there's a high risk that the person doesn't understand everything the AI says.

(this text was originally written in german, then machine translated but manually edited for style (replaced expressions that i would not use myself))
