Do you have kids? Outside of discipline, and even there, I want to have a positive relationship with my sons.
My oldest knows that I am not a writer, there are a ton areas that I can give legit good advice. I can actually have a fun conversation about his stories, but I have no qualifications to tell him what he might want to change. I can say what I like but my likes/dislikes are not what an editor does. I actually stay away from dislikes on his writing because who cares what I don’t like.
I would rather encourage him to write, write more, and get some level of feedback even if I don’t think my feedback is valuable.
LLMs have been trained on likely all published books, it IS more qualified than me.
If he continues to write and gets good enough should he seek a human editor sure.
But I never want me to be a reason he backs away from something because my feedback was wrong. It is easier for people to take critical feedback from a computer than their parents. Kids want to please and I don’t want him writing stuff because he think it will be up my alley.
