Re: Should have been pretty obvious
AR is only really useful in applications where it's vital that the virtual and real worlds be bonded together within your field of view. The marketeers probably need more sales than this very narrow niche would allow for, so they're talking it up as a solution for other use cases, most of which are idiotic.
Warehouse fulfilment wouldn't need fancy integration of virtual objects with real-world ones - a simple HUD overlay showing a route map and destination details would suffice. If this isn't actually being done already it's either because the productivity gains are too small to be worth the development cost, or warehousers are pursuing entirely different means to improve efficiency (another commentard suggested robotics, which seems far more plausible).
