> Devices have never done everything possible under the communications standards they support. Yes they do - that's the point of a communications standard. Any device with a USB 3.0 port will work with any USB peripheral ever, given suitable drivers. Your HDMI example makes no sense because it's backwards; of course I don't expect an HDMI2.0 monitor to be 4K, any more than I expect a flash drive to act as a keyboard - but I absolutely expect a port that supports flash drives to support keyboards, and I expect a computer with an HDMI2.0 port to support 4K monitors. The departure with USB-C is that it isn't a communications standard. Unlike any previous USB port, having the port is not a guarantee that it will work with any peripheral with that plug. The situation with the cables merely reflects this fundamental usability flaw - even if all cables did everything, assessing compatibility would still be confusing.
