The word “master” still makes sense to me, as it has many different meanings, most of which are appropriate for how they are used in technology. However I have always felt that the word “slave” (as the counterpart to master) was/is a mistake. It seems to be a relic of the past where people weren’t really thinking through the terminology they chose. More modern approaches typically use other word pairs, like master/minion, sever/client, active/backup, master/agent, etc. Different pairs are chosen that better describe the relationships, and I suspect those choices were made, at least in some way, to avoid using the term “slave”.
