Agreed. I don't even necessarily have anything against AI edited text but there's a way to sharpen your own writing and there's a way to let its voice dominate. There's a lot of idioms it tends to fall back on (em dashes being the most well known). I'm surprised that folks don't notice these and aggressively reassert their voice.

I use LLMs in my own writing because they have benefits for conciseness but it tends to be a fairly laborious process of putting my text in the LLM for shortening and grammar, getting something more generic out, putting my soul back in, putting it back in the LLM for shortening, etc. I tend to do this at the paragraph level rather than the page level.
