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.

Will USB 5.0 support megawatt charging?  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.

Indeed, USB5.0 will charge your EV at 480V while you use your phone - all using the same wire!

No need to rewire a house, but new houses going forward could be wired with safe USB throughout the house, but higher wattage appliances could be wired directly to high-current power.
TimFox:
And after we are bored with USB 5.0, we will rediscover 120 V, 60 Hz and AWG 12 wiring.

So, my kitchen toaster would need to be directly wired to the wall (and therefore remain in one place).
How would I connect a good-sized vacuum cleaner?  Typical power 1400 W (500 to 3000 W), but needs to plug into various rooms of the house.
That's far more than current 240 W, and 3 kW at 30 V would be 100 A (a bit high for a practicable cable).
You haven't thought this nonsense through, and your proposed solution does not have a real problem that requires it.

Now, in my experience, wall outlets are often in the wrong place, where furniture needs to go.
My solution, for the digital-heavy corner at my computer desk, is to place a proper outlet strip (with 5 120 V outlets and a circuit breaker) that also contains two USB sockets on my desktop.
Should a new low-voltage standard come to pass, I can easily replace such an outlet strip.

My washing machine stays in one place, but I have a plug for it. My stove doesn't have one.
Nobody would be forcing anyone to do anything.
