Large scale networking (ie metro-lan or bigger) because everything needs fibre, and its hard to install manage. Large datacenter management (storage, networking, power) because these skills at scale are dieing out. There will always be another facebook/google/AWS around the corner, and they'll need people who can build effecient datacenters. Ultra low power microcontrollers. Because there is soon going to be a need for no-battery sensors at scale. Radio/comms. Lower powered "edge computing" (ie battery.harvested powered sensors) can't be waisting joules on JSON, so effective binary protocols with strong security are a must.
