We don’t share multiple devices on a single channel anymore - SATA, PCI-E, these techs have only one device per channel (or only a certain number of channels dedicated per device).

Right… This desire to change verbiage on a dead technological concept is kind of stupid. I taught in an R1 institution. This topic DOES come up. And nearly verbatim it was “While it’s unfortunate naming convention existed… we simply don’t operate that way anymore.” It was never a problem.

All this other shit people keep bringing up like git branching… “Master” was a shit name for the main branch, and “slave” doesn’t appear at all. So that’s not even relevant and I simply don’t understand this aversion to words just for the sake of manufactured “hurt”.

Others are saying HA… Except that Master/Slave doesn’t describe any HA I’ve worked with. Nor the terms were used in any of them.
