I see this happening very soon- already, in some cases, for some applications. And I worry that it will be another way for capital to deskill and disempower labour; see Doctorow's "chickenized reverse centaurs" with Amazon drivers and warehouse workers being the classic example.

This was literally the hero utility use case that the HoloLens team previewed to partners back in 2015. The user played the role of "electrician", communicating with another party over Skype who was using a version of MS Paint to "wire" connections in real-time over the HUD.

That technology is now creeper Ray Bans serving ads.

You know Cory Doctorow is just a science fiction writer who never even finished high school, yes? He has no expertise in any of this stuff.

I look forward to the future where employers can demand employees to have brain implants so their "smart helmets" can directly wire into their motor control centers. Voila, self healing and self maintaining robots.

this is already happening in several nations' military for high value equipment. the tech knows how to use most tools, but does not have full expertise on the specific equipment. Smart glasses not only guide the technician but allows remote expert assistance through the glasses.
