AI standardizes writing by applying all the rules correctly. Which is useful if you only want to get a message across. It increases efficiency in translating what you're trying to say for a wider public. The appeal is evident, for we all wish to be understood by our peers.

Writing your own words shows your character. What you deem to be flaws, another can recognize themselves in. This is what creates connection.
Don't underestimate how quirkyness in your writing can impact others. Be flawed. Own your flaws. This is how language is formed. For example: quirkyness is spelled with an ‘i’, but I don't give a fuck, the word makes more sense to me with a ‘y’. Maybe it should be spelled like that. We will only know if we all keep making mistakes. Language is supposed to be lived, not copied.

If English isn't your first language, or you haven't had a lot of opportunity to use it, or you're having trouble with expressing yourself: then AI is a great tool to learn the rules with. Not everyone wants to move into artistry of the written word. Which is fine.
True artistry cannot be copied: it doesn't follow rules.
Like with autocorrect, humans will pick up on the patterns and want to regain their personality. With time, these kind of things balance out. And then the value of true artistry will be really evident.
