It would make zero sense for HoloLens today. The HoloLens doesn't even have a GPS chip. But Microsoft is building the future of MR in general. It's a space they want to own or at least lead, and their investment in Azure services for HoloLens today are proof of that. Obviously what I've described does not really favour industrial use (though I dispute the idea that this would not be achievable in industrial/enterprise environments.)

Indeed, HoloLens isn't great outdoors, however the current technology is capable of it (despite the HL design.) The visor can be darkened to function more like sunglasses, which solves the contrast problem.

I'm just looking 5-10 years out, in terms of what's going to be needed.
