The technology that came after Iphone 1 made it look uncapable, but at the time when it came out it was better than everything else - and it made you feel like you "live in the future". In my opinion some sort of this technology would be very useful. If not this, then something else. Being able to see the map on the car window, or a map when you walk, or information about products (something similar to Google lens but no hands). I can easily imagine warehouse workers using this to tell them which box of little chips to pick-up. Of course everyone talks about building completely automated warehouses, but still there are lots of non automatic ones.
