There will be an awkward period (now?) where you need to know both types of interfaces, but there may be a period where touch, voice, or other interfaces replace the now-archaic file cabinet metaphor that the desktop uses today. Look at Windows and all the metaphors that a child today has no context with which to relate: a manila folder, a file cabinet, a floppy disk, an address book, a wall calendar. It seems likely that this will change, and with it the need to understand today's (and that of the last 20-30 years) desktop computer.
