Saudi Arabia mandates all electronic devices to use USB-C charging ports from 2025

This is a most excellent place for technology news and articles.
Many people have been taught regulation is bad, not much logic to it.
USB-C as a connector can easily last a decade, much longer for just power delivery.
I'd be surprised if USB-C was a limitation on phone technology even by 2040. The bandwidth and power delivery capacity are way beyond what are needed now. Data transfers from phones are going to increasingly move to wireless in that time frame too, I expect.
The limitation on the viability of USB-C with phones won't be the actual technological viability of the standard with respect to phones. Instead, the problem for USB-C for phones will be if another standard comes out and starts being used by other devices that do need higher bandwidth or power delivery capability. Monitors, storage devices, laptops (etc.) will eventually need more than USB-C can provide, even with future updates to its capacity. When those switch over to something new, that will be when phones (and other devices) will need to consider a new standard too.
Why do mobile devices and computer hardware need to utilize the exact same wire? I am fine with their being two, as long as it doesn't turn back into a half dozen types of cables again.
It's convenience and efficiency. At the end of the day a single cable can provide that functionality needed for 99.9% of such devices. Getting everything on a single cable format reduces waste, simplifies people's lives, and even opens up competitive spaces. There's no need for it to be two cables.
But it's already multiple cables. I have like 3 dozen cables, with more than a dozen being USB-C and only like 5 of them will fast charge my phone. This will get more absurd and confusing as it's expanded over varying needs for power per device. I mean at least make some sort of easy cable label requirement.
Your word is the USB-IF's ear. Though generally speaking there really is an enforcement problem when it comes to cables, sometimes cables don't even meet basic USB specs much less high-speed high-power specs.
