Is HoloLens on a trajectory towards success, in your opinion?

Seems to me it's far too expensive for gamers, and not all that useful for business - all I can find online are mock ups of hypothetical business uses, like telling mechanics which way to turn a spark plug to tighten it. To me that doesn't seem very useful. What are the chances a job is done so rarely your workers don't know the procedure already; and yet so frequently it makes sense to build a detailed 3D-modelled instruction pack to replace the normal paper instructions?
