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.
Remember what we said and acted on 20 years ago about technology? Yeaaahh...That's what you said right now.
This is speculation based on the combination of physical constraints and changing usage.
Phone batteries today are in the 10-20 watt-hours range for capacity, or at least iphones are and that's the data I found. Going from the typical ~20W fast charging rate to the full 240W capacity of USB-C EPR would allow a twelve times increase in battery capacity with no change to charge times. Are batteries going to increase in capacity by twelve times in the next 17 years? I'd be shocked if they did. The change from the iphone 1 to the iphone 14 pro max is 5.18Wh to 16.68Wh — a three times increase in 16 years.
Likewise, with data transfer, it's a matter of how human-device interaction has shifted with time. People increasingly prefer (a) automated, and (b) cloud based data storage, and (c) if they do have to move data from device 1 to device 2, they would rather do it wirelessly than with a physical connection. USB4 on USB-C is meant for 80 Gbit/s = 9.6 GB/s transfers. That's already faster than high end SSD storage can sustain today, and USB4 is a four year old standard. People on phones are going to be far more likely to be worried about their wifi transfer speeds than their physical cable transfer speeds, especially in 2040.
Then, on top of all of that... USB will continue to be updated. USB-C's limitations in 2033 will not be USB-C's limitations in 2023, just as USB-C's limitations in 2023 are not the same as USB-C's limitations at its inception in 2014. In 2014 USB's best transfer rate was 10 Gbit/s, or 1/8 what it can do today.
