I have a coworker whose first language isn't English. She uses AI to polish up her writing, particularly long documents. She puts a ton of effort into making sure that it still reads well. Because of this effort her writing is strong and precise. Before AI she made all the obvious mistakes you'd expect from someone who's not a native English speaker. It's very hard to tell that she used AI because she puts so much effort into post-AI copy editing, it's just clear and useful writing. Sure, the occasional non-idiomatic phrase creeps in but those are hard to find.

That's AI writing done right, and it's very different from this other guy I work with who does the whole slop grenade thing.

I have had experiences where customers use AI to communicate and express their issues. Sometimes they produce walls of text like the website exemplifies, but overall it's a better alternative to not be able to explain the issue because you don't know the specific terminology and you are just a layman trying to do things.

Show some love for the layman, we are all laymen in areas we don't know about.
