If "Master/Slave" terminology in computing sounds bad now, why not change it to "Dom/Sub"?

I mentally replaced cars with boats recently and it's been inducing nautical terminology everywhere I speak. Cap'n and Crew sounds great for this usage, it feels honest without the shock of great grandpa's heavyweight authoritarianism. I usually wind up stepping down to Spongebob or Pirates to filter out seriousness too, as long as the packet arrives and the replicas are jolly.
