Artificial intelligence is an old dream but a fairly young discipline, which has developed since the late 1950s as an interdisciplinary branch of computer and cognitive sciences aiming at computational models of human cognition. In its strongest version, the one which was predominant for at least the first two decades of its history, between the mid-1960s and the mid-1980s, and is now often labelled Strong AI or GOFAI (good old-fashioned artificial intelligence), AI worked on the theoretical basis of the construction of software and hardware, and hence computers and robots, whose behaviour would eventually be at least comparable, if not superior, to the behaviour characterising intelligent human beings in similar circumstances, e.g. recognising one’s car among many others in the street, driving it to the supermarket safely but at a reasonable speed, parking it successfully, remembering to lock it carefully and then inferring that one will not be able to drive it home because one has locked the keys inside, and so one had better get someone to help.
