Web stack replacing "Java GUI" is no big surprise, and totally dissimilar to the great-grandparent comment that implied that there might be a shortage of low-level C jobs. Python and Ruby have not eaten C/C++'s lunch, as far as I know (well, maybe snacked on it a bit). OSes, browsers, games, embedded... still seems to be lots of call for C/C++. Java GUI was never in that class, so it's not at all surprising to see it obsolesce.
