I’ve had the same thought re: AR glasses with a HUD for mechanics/construction workers, there are a lot of cool possibilities.
Yeah ... then you can have basically anyone off the street do the job. A great opportunity to pay your jumbo jet mechanics less than taxi drivers.

We worked on a proof of concept using HoloLens for an engine teardown team at a trucking OEM. Ran into issues around network, security, the Hololens itself and a general disinterest from the teardown team but there's a lot of room to run in this space. It was a fun, if frustrating, project.
