Copilot is helpful for handing formatting and repetitive structural stuff. It doesn't need to actually create the content to be useful.

Personally, I’m a lot better at recognizing good writing than producing it, and LLMs are great at being a “calculator for words.”[1] Writing posts became a lot easier once I got an automated editor I could tell to “break up this run-on sentence to make it less confusing” or “rearrange these paragraphs so I introduce concepts before I start using them”. The end result is still the same, but this way I save a lot of time I used to spend glaring at Roget, Strunk, and White.

I found it very useful for proofreading. It's easier than copying/pasting the content into ChatGPT or similar, as it's right in the editor. I disabled the autocomplete though, as I found it breaks my flow of thoughts
