I am telling you my own preferences, as a native speaker of English. I would rather read my coworkers' original output in their voice than read someone else's writing (including a machine edit of their own text).
I understand the sentiment, even appreciate it, but there are books that draw you into a story when your eyes hit the paper, and there are books that don't and induce yawning instead (on the same topic). That is a skill issue.
Perhaps I should add that using the LLM does not make me faster in any way, maybe even slower. But it makes the end results so much more pleasant.
"If I Had More Time, I Would Have Written a Shorter Letter". Now I can, but in similar time.
Recently there was a non-native english speaker heavily using an LLM to review their answers on a Show HN post, and it was incredibly annoying. The author did not realize (because of their lack of skills in the language) but the AI-edited version felt fake and mechanical in tone. In that case yes, the broken original is better because it preserves the humanity of the original answers, mistakes and all.
You know maybe it is annoying for native speakers to pick up subtle AI signals, but for non-natives it can be annoying to find the correct words that express what you want to say as precisely as in your mother tongue. So don’t judge too much. It’s an attempt at better communication as well.
