Well, be happy because you are wrong. Many businesses don't need VR - like the corner market and such - but many businesses do. Anything design related like engineering companies, architecture firms, all the way to travel and entertainment. Hospitals and medical research, automotive, and so on. All will benefit greatly from being able to see and explore things they never could before. This puts million dollar 3D visualization facilities in reach of just about everyone.
And while there are many lining up to play GTA5 or similar first person mayhem kinds of games, regular people can have the equivalent of million dollar simulators in their own homes both for training and for enjoyment. Flight and driving simulations are transformed when the visuals become what you would actually see from cabs, cabins, and cockpits.
There isn't one killer app. It's a killer view in all sorts of different apps. Until you actually experience it it is hard to describe well enough to convey. What I can tell you is I have flown the real deal commercial and military flight simulators. Full motion, hemispherical projection, etc. They may have real cockpits but the out the window view is a 2D projection and flat. Very cool but not totally immersive. Do that in an Oculus Rift and now everything is 3D. You can use a mouse to aim and click on knobs and switches which isn't so realistic, but whatever plane you want to fly is simply a matter of programming. And it is far more immersive and real feeling than any simulator I've ever been in. That is no exaggeration. It's the same for driving sims. In 3D you can "feel" the car breaking loose just from the slight changes in angles that you can now perceive with the head tracking and 3D view. It is astonishing.
Architecture firms have been going nuts that they can now actually enter their creations and fine tune things as well as show them to customers. It's not just a "this is nice" kind of thing. The reports are that the architects are having "wow" moments and are modifying designs that they thought were fine before but once they can explore them in virtual space, they see that things could be even better.
Plenty of people won't have any use for VR at all. But plenty of others will see it as a game changer for their profession, their training, their hobbies, and possibly even their health. It's something you really need to experience to understand. And for the uses that really will push VR into all aspects of any kind of design and training, the game demonstrations don't cut it either.
VR is very weird. Those that haven't seen what it can do are much more likely to claim it is unimportant and will never catch on. Those that have seen can see the potential in everything from games and sims to real world valuable insight generators in many professions. I would bet you haven't actually experienced VR and therefor suffer from the inability to extrapolate. Trust me on this. When you put on an HMD and look around some environment you could never see otherwise, any environment that a computer can generate and synthesize, you will understand.
