Why stop at training... why not just have the hololens show you every individual step, day after day? It could work for fast food, manufacturing, retail.

In the end working-class humans will just be skeletons to be operated by instruction. The key requirements will be: ability to stand, not being too large or small, reading and listening in the chosen language, following orders, manual dexterity, and showing up to work on time sober.

We won't need expensive robots with servos and sensors.

Now you can see why so many business interests are (secretly or otherwise) pushing for open borders. Anyone could do this stuff.

Extra: I can see why the military contract hit the news - this will be a critical piece of equipment for soldiers. Route/map overlay, location pinging, friend/foe indicator, weapon status...

2-3 hours of active use is a big limitation though.
