"man" is at least short for "manual". There's nothing essential about master/slave so why not just switch to primary/replica?

Because the master forces the slave to do it's bidding.

But ... so what? For one thing, the metaphor doesn't have to go that way. For another, "leader/follower" captures that too.

> enslave "10.0.0.2" I know it is functionally immaterial, but boy howdy do I ever wish we'd chosen a better convention for how to refer to the relationship between these system components.

I find it's a useful heuristic for knowing whether someone can think clearly and abstractly. Kind of like the "all green birds have two heads" test.

Could you expand on that? I get the reference, but what is your heuristic?

Someone who has a problem with master/slave terminology probably can't think abstractly (in the same sense as someone who fails the all green birds have two heads test).
