Obviously if the technology community develops something better we'll swap to it legally. Laws aren't set in stone for all eternity. It's bullshit that you have to own so many cables of different connectors just to be able to charge all your devices at home. if anything, THAT'S what's causing waste.

Also, as an electrical engineer, there's only so much improvement you can do to plugs and cables. Most of the improvement is with the devices themselves. If you need to use more pins in a cable, then add them in there but keep the shell of the plug the same. Most of the time plugs don't even use all the pins they have available. As long as you can connect a USB-C cable to any device that uses USB-C and it works, then innovate within those bounds.
