That seems like stocking bins is a solvable automation problem too. Trucks can be unloaded by vaguely smart forklift bots. Box moving bots are a thing already. Box cutting bot? They showed an item picking bot in the video: look at the barcode, maybe do a little tetris and fill a bin with them. Empty box crushing bot? Repeat.
Pallets shift in trucks, often requiring the warehouse crew to climb in and untangle things.
Also trucks are often dropping off a few pallets and not unloading entirely. The warehouse crew talk with the driver, sign way bills, and other things.
Yes these things could be solved but not by one company or quickly.
