Here's an idea. We could use differently-shaped connectors for different purposes! Time to admit USB-C was a naïve idea that gave us a mélange of compromises and inconsistencies, thoroughly coated in squid ink.* * Apparently USB-C specifies the color must be black. There goes that method (color-coding) of identifying different capabilities.
And while we are at it, maybe also bring back laptop docks that work by setting a laptop down on top of it? With connectors on the bottom of the laptop instead of a cable to plug in? One can dream
I'm still rocking a x230 with the old Lenovo dock. It's a pleasure to just put it down/ pick up without any attached cables. Though didn't the Lenovo X1 had a nice bottom-attachee dock too?
