Sensors and real time data - As sensors become cheaper, ubiquitous and networked, integrating all the data from these sensors on the fly will be able to produce previously unseen real time views of the world around us.

Parallel programming - With multicore processors now the norm, parallel programing is no longer just an interest of high tech labs, but a become a hot topic of programmers everywhere.

Robotics - Just because.
