How Many Robots Does it Take to Run a Grocery Store?

Let's take a tour of Ocado's automated grocery warehouse in London. The point of this video from Tom Scott is to make us think about how networks of robots may be many individual robots, or one robot made up of a colony of moving parts, like a Portuguese man o' war. Yeah, but what we are really seeing is the future, where the robots have taken over the grocery business and eliminated not only shopping, but grocery workers. Still, considering how many cars are in the parking lot, it appears that robots still need a lot of supervision.
