I wish they would have developed a data-over-powerline protocol specifically to link your monitor's USB to your PCs. Especially for computers 20+ years ago, almost everyone plugged their monitor into the same AC power jack as the PC. They could have had a USB 1.x connection between the monitor -> AC power -> power supply -> motherboard so you could plug your slower USB devices into your monitor and skip the USB cable. Apple had this, I guess, with imac, and I know about powerline ethernet devices, but I think they skipped the most obvious use case.
That's because anything-over-powerline is absolutely and objectively terrible.
You already have a high throughput data cable between your PC and monitor. Carry USB over displayport or whatever. At least then you can use more than one PC on an entire city block.
