I was thinking about this yesterday; I had air-conditioning installed and the guys spent an hour measuring and marking the walls before deciding where to mount the unit and drill holes. I kept thinking "get a HoloLens, take a picture of the back of the unit, look at the wall and pin the picture where you want, start drilling". I think interior design will change a lot in the next ten years.
