I'm sure it will be, but the technology isn't there yet.
With AR/VR you can at least project a screen way bigger than any desktop, all the way to true immersion. Coding, design, social media, video games - most things you do on desktop, can benefit from VR.
But right now VR has a lot of issues: bulky headsets, low-poly because you need really fast framerate and double render, hard to track movements accurately, hard to control, and most of all hard to implement. It's a lot more complicated than desktop or mobile.
