Also engineering—meaning physical engineering, not software. Think: CAD, simulations, architecture, manufacturing. You could do a virtual walk though of a factory before breaking ground, or just look at the output of a numerical simulation to get a gist of it instead of spending time writing summary tools. When VR controllers get there you could program an industrial robot arm just by doing the activity yourself in a simulated environment.
