> As a person who's been participating in human-to-human communication your entire life, you probably have a pretty well-developed sense of how to structure the flow of a piece of communication.

Not OP, but this is where you're wrong. The vast majority of people, myself included, have difficulty structuring communication for effectiveness to a wide audience. When I manage to pull it off I'm very proud of the work, but I can't just sit down and do it. Review with an LLM helps me find those places where it CLANKS, distracting the reader, taking them out of the flow. This is why every professional writer has an editor; good communication is quite hard.

He's not writing the bible. He's writing a blog post about segment registers. It's fine if there's a sharp edge here or there. You're probably better at communication than you think, and your readers are probably less picky than you're imagining. An occasional sharp edge in your text is not the end of the world.

The original texts of the Bible have lots of “bad grammar” and “poor spelling”, too!

Just sweat more blood.
