Have you ever had someone else edit your work, comment on it and provide alternative phrasings or organization? LLMs are pretty good at that, available any time and give instant results, as long as you understand that they work differently from a human reviewer - you can't expect it to be of the quality you'd get from a subject-matter expert or highly skilled writer, you have to lean into the LLM slot-machine model where you just get some alternative options. But it's incredibly useful when you're stuck in a rut with how to conceptualize or explain something, or even when you're not, and just want to visualize some alternatives that come from somewhere outside of your own head.

I think of it like a power thesaurus. Thesauruses get a bad rap for people just using them to look for ten-dollar words, but they're super useful for finding ways to articulate things differently, which can sometimes lead to bigger insights or ideas about restructuring the content.

It's on the author to look at what's suggested by the LLM and decide whether or not to use it, and there's an inherent danger in having one's voice overridden by simply accepting too many of the recommendations as-is. But that's between the author and the tool. I won't make any comment here on the article author's prose or how they maybe did or didn't use LLMs.
