“Since its dawn as a discipline, AI focused on simulating and reproducing human-like mental processes using formal structures, chasing the high quality of reasoning. However, with the challenges posed by Cyber-Physical Systems, AI needs to take into account concrete real timing performances in addition to abstract reasoning about time. The AI definition of intelligent agent seems to perfectly apply to CPS. Nevertheless, to be real, intelligent agents need to deal with, reason about and act in time.” – When Rationality Entered Time and Became a Real Agent in a Cyber-Society
