Imagine you're working your 35-hour shift at the Fulfillment™ Center and all around you there's robotic eldritch horrors scurrying through the two-storey high shelves
Factory robots that move in general are kind of gimmicks, except for those roomba things for Amazon warehouses.
An assembly line with robotic arms has been standard for a long time now. And having many such arms working at the same time is normal. And each robotic arm will be doing one extremely narrowly defined task.
Anything involving autonomous judgment and mobility introduces uncertainty.
Neuralink-equipped wageslaves mind-projecting into robo-octopuses, traversing the storehouse-grid with the aid of their many-suckered appendages. Navigating via implicitly interfacing with the warehouse's AI overseer.
Even if you don't have an assembly line and more of a job shop. A stacker crane is a better transportation method and you can build each station to be able to load from the crane directly. So the only case where you need a robot arm is to take a part and put it in a fixture.
