VR and Dataflow programming would be a really natural fit, based on the concepts they are showing here. Dataflow programming with a good UI displays physical objects which represent functions, and lets the developer connect the pipes, as it were.
Throw in an editor which lets you open up the objects and change the wiring inside, and you could have a very powerful yet intuitive, method of programming in a VR.
Article writer here - thanks for the comments. I think the key for VR is that it will be awesome for specific domains (e.g. game development) but won't show much benefit to general programming.
Once VR has become more commonplace then I see it integrating more and more into programming as it becomes useful in other scenarios.
