Why get rid of them? Automatisation should not mean getting rid of people, it should mean letting them do other things. In this scenario the editors could spend more time on their own writing instead of having to look at junior writer's texts
In the same sense that someone who reviews a (IT) technical procedure is not necessarily a systems administrator, but someone who sees things from an angle to ensure RACI model is followed throughout without any generalizations such as "backup is taken" (by who? using which tools? which systems/data are backed up? how often? how long do we keep the tapes? how often do we trash the tapes? where do we store the tapes?). I haven't taken a backup for more than a decade, but I would shred a backup procedure to pieces. If you remove me from the review cycle, I won't go back to writing procedures.
