Imagine the world where everything is fully automated. You arrive at a city, order a self-driving taxi, do a self-check-in at the hotel that is managed by robots, order a food that is cooked by robots, using ingredients delivered by robots, grown in farms managed by robots. The hotel itself was 3d printed and the city district was planned by an AI algorithm optimised for economic utility. How many iterations are there before this is the reality? It would probably take a century before something like this is the norm.
