Funny how people get heated over things that don't matter. OK, it has been one way for a long time. But had it been Parent/Child the same amount of time, would it be any different?

As long as you know the meanings of what is used, it doesn't matter what they are. If someone would rather not use master/slave, let them. No one is stopping you from making a choice to keep using it. You also might have to interact with consequences for that choice, but that's what you get for working with other people. 🫠

What the fuck is wrong with computer people?

It’s been primary/secondary and main/secondary in the automotive hydraulics world since at least 2000. I know because my hs car repair class used master/slave and I had to do a double take for a second back in ‘01 looking at the manual before bleeding the brakes on a focus.

Is everything else in the hydraulics world also primary/secondary?
