Stacking shelves in a supermarket is a perfect example. 1000s of products means that a bit of experience is required to know where everything goes in order to quickly stack. With a HUD, workers become productive much faster (and are more inter-changeable) - which is something large enterprises love.

Knowing where to stack things is something humans are capable of rapidly learning. It’s not a big part of the workload of stacking shelves. The actual physical effort dominates the work.

A shelf stacking robot is even better at knowing where things go and won't get a backache and file a worker's comp claim.
