We all are users of technology and services, but the way we use them strongly depends on who our 'interlocutor' is: a machine, a software application or a person. The contributions of this volume look at the concept of the user from various perspectives and continue to discuss the theme started in volume three on the user of the artificial.

The human ambition to reproduce and improve natural objects and processes has a long history, and ranges from dreams to actual design, from Icarus's wings to modern robotics and bioengineering. This imperative seems to be linked not only to practical utility but also to our deepest psychology. Nevertheless, reproducing something natural is not an easy enterprise, and the actual replication of a natural object or process by means of some technology is impossible. In this book the author uses the term naturoid to designate any real artifact arising from our attempts to reproduce natural instances. He concentrates on activities that involve the reproduction of something existing in nature, and whose reproduction, through construction strategies which differ from natural ones, we consider to be useful, appealing or interesting.

The development of naturoids may be viewed as a distinct class of technological activity, and the concept should be useful for methodological research into establishing the common rules, potentialities and constraints that characterize the human effort to reproduce natural objects. The author shows that a naturoid is always the result of a reduction of the complexity of natural objects, due to an unavoidable multiple selection strategy. Nevertheless, the reproduction process implies that naturoids take on their own new complexity, resulting in a transfiguration of the natural exemplars and their performances, and leading to a true innovation explosion. While the core performances of contemporary naturoids improve, paradoxically the more a naturoid develops the further it moves away from its natural counterpart. Therefore, naturoids will more and more affect our relationships with advanced technologies and with nature, but in ways quite beyond our predictive capabilities.

The book will be of interest to design scholars and researchers of technology, cultural studies, anthropology and the sociology of science and technology."

In recent years a vast literature has been produced on the feasibility of Artificial Intelligence (AI). The topic most frequently discussed is the concept of intelligence, with efforts to demonstrate that it is or is not transferable to the computer. Only rarely has attention been focused on the concept of the artificial per se in order to clarify what kind, depth and scope of performance (including intelligence) it could support. Apart from the classic book by H.A. Simon, The Sciences of the Artificial, published in 1969, no serious attempt has been made to define a conceptual frame for understanding the intimate nature of intelligent machines independently of its claimed or denied human-like features. The general aim of this book is to discuss, from different points of view, what we are losing and what we are gaining from the artificial, particularly from AI, when we abandon the original anthropomorphic pretension. There is necessarily a need for analysis of the history of AI and the limits of its plausibility in reproducing the human mind. In addition, the papers presented here aim at redefining the epistemology and the possible targets of the AI discipline, raising problems, and proposing solutions, which should be understood as typical of the artificial rather than of an information-based conception of man.
