It is used by NASA and they are stupid as per your post.

Where did you see the "rigged demos"? It works as shown in the demos if you even understand what it can do and do not. Your 20 minutes on hand demo never shows/teaches you any thing.

It is hardly "used" by NASA. As a conceptual study for the whole premise of AR they have tried it out in concert with Microsoft, but the project has gone entirely silent. And no, it doesn't work as shown in the demos -- it's very low resolution and has movement and 3D mapping issues. It will obviously improve, but I wouldn't be dropping thousands on a first generation unit, as it is certainly money down the toilet.

You are the first one to say it has "3D mapping issues". I can send you links with experts saying Hololens is the holy grail of 3D mapping and tracking.
