Such things have been in use for the last 15 years here in Europe. Fully automated warehouses where one of the few employees left only has to pick up the goods after they have been brought to him from the shelves by a bot.
They are way faster than human labour and can use the storage space more efficiently. Whenever you have a storage area with big shelves and tons off different material in them you will find automated systems.
They are already developing systems that will make forklift drivers unnecessary. Automation is on the move big time.
Welcome to the world of "I want to buy cheapest" and "I want to make the maximum profit".
