It seems like USB A/C are going to be that. You can already buy outlets that have both mains and USB ports, there are even dual USB C outlets now, that can do 30 watts: https://www.amazon.com/dp/B07PTWG5DV

The author makes the valid point that USB-A is too low power, and USB-C requires active cables. (Translation: expensive or dangerous)

I was going to link to that exact product. I put in the USB A one a few weeks ago and love it. When the iPhone 12 is released I’ll switch to USB C.

Interesting idea, but running an extra set of cables is a non-starter. The cost/benefit analysis would never make sense for existing structures, and newly built structures wouldn't do it unless it was almost certain to become a universal standard. This is a classic chicken-and-egg problem.

You would also still need something similar to a wall-wart to step down the voltage to whatever your device actually uses (e.g. from 12 V to 5 V to charge your phone), so its not clear how much benefit there would really be from such a system.

Whatever specs we adopted would probably also end up not being appropriate for some future devices, so we'd probably go back to a substantial number of devices bundling their own PSUs anyway.

Interesting idea, unlikely to ever be worth the cost. If wall-warts really bother you, then just invest in some wall outlets with integrated USB sockets - there are many good options on the market.

Do to circumstances beyond our control, we had to replace all the outlets in my parent's condo, so we used the USB (A) outlets. It works quite well. I do wonder if we will see USB-C quick charging outlets.

Is "Digital Electricity" a real thing? Its billed as an alternative to AC or DC. This may be as good a place as any to ask this question, but I am a hotel developer, and we've had a few people reaching out to us trying to sell "digital electricity" that sends high voltage over cat5 (up to 2000w per the Belden materials) by essentially sending high voltage for very brief blips with the ability to switch off before any damage occurs if a short is detected. they claim it is supposed to be significantly more efficient, doesn't require electricians to run cables, and its safer. I declined... but im still curious. basically every device in the room is connected via lan to a power server.
