I used to think like this. But I've come to realize that editing, whether by a professional or an AI, is a good thing. It flags when I think I'm being clear, but I'm not. Sometimes that's as simple as reworking a sentence to be less verbose, but other times a simple edit can indicate that the entire paragraph is confusing. LLMs can be quite helpful here, because you can actually ask them what they understand, and they'll give you a good idea of what your readers are actually reading. Even when you are a good writer, it helps to understand what people are actually taking in. A good editor will do this, as will teaching students, but an AI will do it with you all day without complaint and without embarrassment.
