The IT department isn't done, but a lot of jobs will be. With technology becoming more self-evident, the cloud and the proliferation of mobile assets, most front line jobs and many backend ones will go away. Cloud providers don't need the level of personnel to run their infrastructure that most IT departments do. The end result will be fewer back-end jobs and desktop support. I think developers and programmers will be immune to this as well as PMs. Of course this will take time, but in 10 years you won't recognize the place as they say.
