Not talking about my ports. Also ports can be installed the wrong way by the manufacturer. I had a pc case that the front usb ports upside down. But again, usb ports can be installed vertically, in which case it won't matter if you know which is up or down your usb plug, because now it's left or right
What about the back of your tv? Or friend's PC? Or library computer? Or phone charger? Or... Any other Universal device using the Universal Serial Bus...
You may learn YOUR devices, but you may also have to interact with other devices at times and USB didn't make it easy in the past.
Now, type C is a thing and it helps with plugging it in right the first time, but that one has the HUGE issue with allowing any protocol since USB 1.0 and everyrhing else is optional. So even though you can plug a type C monitor into a type C microphone, nothing will happen, so it's not stupid proof anymore.
