When I read documentation, I'm not there to enjoy the experience. I'm there to find out how the documented thing works and how to use it. It's not a novel. I'm not there for entertainment.

Chasing readability without maintaining accuracy is a failure in the context of documentation no matter the motivations involved.

I'm not saying that readability can't be a consideration when making documentation. I am saying that if you discard accuracy in the process, you've fucked up quite badly.

This anecdote would likely be very different if the AI-modified version had been passed back to engineering for a review before sending it out.
