Alibaba, who pioneered and popularized mobile payment, just launched the first unmanned hotel, "FlyZoo" hotel. Providing some services by robots with AI, "FlyZoo" hotel will definitely be an indicator of a trend toward unmanned commerce. Behind the futurist impression stands a way to cut the cost of human labor: introducing robots with AI. A widespread unemployment caused by the substitution of robots for human labor in the future concerns a lot of people today. As for shrewd consumers, whether a lower human labor cost will lead to cheaper accommodation remains questionable.
