I had read Forever Peace not all that long before writing the story (small as it was) for the first AI War, and I had remote-piloted drones in mind at the time, I think. But with added AIs in there to compensate for slower human reaction times, and humans having to coordinate multiple ships at once due to shortages of staff, etc. The sort of "safe AI" that is really just non-intelligent algorithms for autotargeting, etc. It's running an algorithm and coming out with a certain result, and the humans' job is getting them in the positions where the algorithms will do the right thing.
As a fan of Ender's Game, I was also figuring on something along the lines of an ansible.
