There is a Whole Foods store one block away from my house. Next to it I can see a number of bicycles with some type of trailers. They are used for deliveries. With such a bicycle a person can deliver easily 3 times more than a person who just pushes the groceries on a cart. One way to look at this is to say the bicycle increased someone's productivity by a factor of 3. But another way to look at it is to say that one man and one bicycle can do the work of 3 men now. So 2 men will lose their jobs. A bicycle just replaced 2 men. The bicycle does not look like a robot at all, but is just as good, if not better, at replacing human workers. The same with other jobs. You don't need to replace 100% of the workers. You just need to bring machines that increase someone's productivity by a factor of 5, and boom, you are able do let go of 80% of your human workforce. At the same Whole Foods store there are lots of self service lines now. My guess is the number of cashiers went down by at least of factor of 3. Amazon has shops where you don't even need a self-service line. You just go in, pick whatever you want from the shelves, and leave. The cameras keep track of what you pick and charge you appropriately. They started using this technology in Whole Foods stores (one in Washington DC is already functioning, one in LA is coming this Fall). I went on a road trip last week. I noticed there are no more manned tollbooths. Everything is fully automated. That's probably some thousands of human jobs lost. Big win in my opinion, the passage through the tollbooths is much, much faster now.
