This is something I've worked on so I can comment a bit. The most popular use case I've seen so far is AR manuals, with the sell that you can have technicians up to speed on a piece of equipment without needing human coaching or training. I was shown a demo in the context of robotics recently where you look at a robot and explanations of signals in the wiring harness were shown, hydraulic connections, wear parts, etc. It was visually pretty impressive but quite telling that the two most interested people were my manager and the CEO. The engineers just kinda sat looking at each other with a non verbal "Must have been a fun project to build huh? I'll stick to PDFs".
