Yeah. To me PS/2 is
THE keyboard interface, and should stay.
But it's useless to debate about it. Love it or hate it, we have to face the reality: PS/2 is history.
I still got a motherboard with a PS/2 port (MSI MEG); wasn't easy; limits your choices pretty much; every MB comes with Bluetooth and WLAN by series, while I still don't understand - I refuse to understand - why a stationary machine - "Desktop"/"Tower" - comes with WLAN by series anyway.
However, Unicomp also still sells PS/2-KBs.
I'm almost used to USB keyboards. I have to. Even if I still have this feeling in certain situations you'd be better served with a PS/2...
Doesn't matter. If I've seen right, PS/2 will also be removed soon from future FreeBSD, anyway.
So, goodbye good old PS/2. You served us well those many years. Some of us will miss you.
My conspiracy theory of USB is, it was ment to expand the market for useless toy-crap to be attached to computers by morons, like fans, lamps, coffee mug warmers, or rocket launchers (no joke! ddg it!)
The official idea of USB was to get rid of those confusing vast amount of specialized, incompatible connectors:
2x PS/2 for keyboard and mouse, DVI or VGA for monitor, centronics parallel port for printer, optional by card: an own joystick port, and RS232 for maybe anything else - a madness!
Now there is one connector for everything (besides monitors, LAN, and audio): USB.
Now everything is so easy, simple, clear, and completely free of any confusion:
There are connector types A, B, C, mini-B, micro-B for USB-2, micro-B for USB-3, for either USB 1.0, which practically does not exist anymore, or for some or only one of 2.0, 3.1 Gen 1, which was 3.0, now is 3.2 Gen 1, not to be confused whith 3.2 Gen 2, which was 3.1, then 3.1 Gen 2, which is also not to be confused with 3.2 Gen 2x2. Some are interconnectable, others not.
Besides I always need to turn a USB-A connector two times until I get plugged it in, you should have seen me trying the first time to plug in a USB-A-3.2 Gen 2 stick into a USB-A-3.0 plug... Now even form, size and color are not enough anymore to tell one connector from another, you need to look with magnifying glasses into it!

Crystal! No comparison to the confusing connector and cable chaos we had in the earlier days!
Upcoming is 4.0. I'll bet this brings at least four new connectors, which are not compatible with any former one, 3.2 Gen 2x2 becomes 4.1 Gen 1, when 4.0 Gen 2 comes and becomes 4.1 Gen 2. Anyway I wouldn't be surprised if it will provide 16A@230V AC. Now everything can be used in USB: vacuum cleaner, dishwasher, or charge your EV from your laptop...
However, one bet I will win for sure:

will bring an exclusive connector of their own that fits absolutely
nothing, not even their own former models.
