This issue aims to focus its attention on two different main elements: the moral questions emerging from the introduction of artificial intelligence (AI) in our everyday world and the way AI can redefine what it means to be a human being by reshaping the way we look and understand ourselves. This issue does not merely refer to artificial intelligence as a specific branch of computer science, and it is not just limited to the analysis of particular computer programs, but it focuses on the broad spectrum of intelligent robots, machines, and systems which use AI to some extent to act in our everyday world. Thus, it also includes technologies like robotics, wearable computers, mobile applications, and smart cities to better tackle the change in our society introduced by AI in a more precise way.
