They have had these kinds of things, in more basic form for quite a long time. There's no need to have MagicLeap style realism to realize 'possible industrial gains' - and yet there aren't any such companies doing an IPO soon. Google was keen on using Google glass for all sorts of relevant things, and so far, they've failed. In the first link, I see someone saying 'this could be huge'. Emphasis on 'could'. The second link is similar. Some nice feasibility/test studies. Have they made a purchase order yet? No? Why not? Is anyone using this in production yet? No? "It's tough because industrial giants are slow moving, and very particular about certain hard things" Yes, exactly. Slow moving, very specific - and even then, the number of such workers is not that big. If Airbus and Boeing both make orders for 50K units each, that's still not enough to make a company work - and those would be the biggest clients imaginable. i.e. bad business. They're not going to get a $5 Billion dollar valuation by selling to these clients, at least not for a very long time.
