Due to the rise of artificial intelligence (AI) technology, discussions are progressing on how robots could replace human labor. Conventional surveys have shown that human work is expected to gradually be replaced as tasks become automated. However, human labor changes on tasks, not on jobs. The modification is taking place in human-system interactions. There is an extremely creative process of labor emerging in this area. We conducted a survey at the world's first robot hotel - also called a Henn-na hotel ("strange/change hotel") in Japanese - which already uses robots for most of the work done there. We discovered that human work is divided into task units, and that robot actions affect human emotional control.
