Eh, "master/slave" has been controversial for some time. I worked on a team with a master/slave product, and it always made me uncomfortable. Master/servant would be better, but a dominant replacement takes hold, no one knows what you're talking about when you say master/servant.. I, personally, would like to see the terminology master/slave replaced, and I am not a politically correct person whatsoever. There is a line, and "slave" is over the line. The mainstream media isn't talking about it, but there aren't a ton of black people in high-tech either. And, American slavery was one of humanities greatest evils. "Bro" is nowhere near the line.
