I never knew that USB-C extensions are not allowed for a reason (www.youtube.com)

There is a reason for USB-C extensions not to be part of the standard. They can be bothersome in the best case and dangerous in the worst.

USB-C somehow managed to be the worst "standard." Hopefully the next big USB port doesn't allow for so much variance. I don't see why a specific wattage and data transfer rate isn't included in the specification. I can scarcely believe they managed to standardize it so well that I can plug the wrong cord into a port and break something.

    Per the video, the usb-c connector on the cable has a chip that communicates the maximum current that it can safely pass. By plugging it into a lesser rated usb extension cable, that assertion is now wrong, potentially dangerously wrong if enough current is sent that the wires in the extension overheat.
