You probably havent learnt that usb-c is just the connector type and all existing usb devices that has a cable with double ends can be run on a for example microusb-> usb-c cable instead, it doesnt need to be usb-c to usb-c on devices, but thats what new devices will be in not so long time i guess, most new devices will probably have usb-c port on the device and ship with both usb-c->usb cable and usb-c->usb-c during transition phase (for example the new lacie usbc drives come with both cables included)
You missed the entire point of that portion of the conversation but okie dokie...
