This article incredibly well written (by a writing teacher). Some choice quotes

Writing isn’t just the production of sentences – it’s the training of endurance by way of sustained attention. It’s a way of learning what one thinks by attempting to say it

AI’s prose is perfectly mediocre, producing the sort of inert gloss that reads like a Frankensteinian amalgam of MFA-workshopped writing, an unintentional parody of the style it mimics. The resultant stories and essays are simulacra of thought, generated via pattern recognition learned from millions of human-penned words, rooted in no particular experience by no particular person

By contrast, student-written fiction is gloriously flawed, a struggle on the page between what the author is trying to say and what’s actually being said. The prose stumbles in a way reminiscent of a foal learning how to walk: even in their trembling legs I see hints of future grace. Such clumsiness is necessary; its absence would be proof of the foal never having learned to walk

Author is probably going to be fine in the future. This already reads like a prompt:

"I offer these directions for writer and reader alike:"

"Read the story at least twice. Mark what works and what doesn’t – underline great sentences, flag clunky syntax, gaps in logic and unrealistic dialogue. Ask yourself: does the story work? Why or why not? What could improve it? Answer in a signed letter to the author, attached to their story. Give your honest opinions. Remember that an effective peer review demands close reading of the text accompanied by a boldness of spirit."
