Why should I spend money to re-wire my house, for no benefit to me, to help your silly idea? What if I need to plug something into a wall outlet, for example in my garage, while wearing gloves? |

You will do it because it makes your whole digital life more convenient and simply better. USB 4.0 introduces the new Power Delivery 3.0 specification, which permits mains passthrough with automatic negotiation of voltage and frequency. Gone are the days of travel adapters, step-up transformers or voltage switches hidden on the rear panel. All you need is USB 4.0 enabled devices and a USB cable, and USB 4.0 mains which you will invest in because everybody does. Revision 4.1 will add a new type D connector, which can be rotated arbitrarily in 90° increments and includes additional wiring to carry 20Gb/s data and three phase power for your most demanding peripherals such as intelligent welders, electric vehicles and similar. |

Not I, said the fox to the little red hen. |

It's really inconvenient to have to wait for my phone to charge up. I'd like if it could be charged in 18 milliseconds instead. |

Instead, to minimize EMI problems from crappy switching DC supplies, we can install rotating shafts at a safe height above the floor, near the ceiling, and run belts down to generators mounted on the equipment. No fossil fuel need be involved: the shafts can be driven from windmills. |
