ABSTRACT: Achievement of human level machine intelligence has long been one of the basic objectives of AI. Officially, AI was born in 1956. Since then, very impressive progress has been made in many areas—but not in the realm of human level machine intelligence. Anyone who has been forced to use a dumb automated customer service system will readily agree that human level machine intelligence is not yet a reality. Today, no machine can pass the Turing test and none is likely to do so in the foreseeable future. During much of its early history, AI was rife with exaggerated expectations. A headline in an article published in the late forties of last century was headlined, “Electric brain capable of translating foreign languages is being built.” Today, more than half a century later, we do have translation software, but nothing that can approach the quality of human translation. Clearly, achievement of human level machine intelligence is a challenge that is hard to meet. Humans have many remarkable capabilities; there are two that stand out in importance. First, the capability to reason, converse and make rational decisions in an environment of imprecision, uncertainty, incompleteness of information and partiality of truth and possibility. And second, the capability to perform a wide variety of physical and mental tasks without any measurements and any computations. A prerequisite to achievement of human level machine intelligence is mechanization of these capabilities and, in particular, mechanization of natural language understanding. In my view, mechanization of these capabilities is beyond the reach of the armamentarium of AI—an armamentarium which in large measure employs classical, Aristotelian, bivalent logic and bivalent-logic-based probability theory. To make progress toward achievement of human level machine intelligence, AI must add to its armamentarium concepts and techniques drawn from other methodologies, especially evolutionary computing, neurocomputing and fuzzy logic. A key contribution of fuzzy logic is the machinery of Computing with Words (CW) and, more generally, NL-Computation. This machinery opens the door to mechanization of natural language understanding and computation with information described in natural language. Addition of this machinery to the armamentarium of AI would be an important step toward the achievement of human level machine intelligence and its applications in decision-making, pattern recognition, analysis of evidence, diagnosis and assessment of causality. Such applications have a position of centrality in medicine.

FUZZY LOGICProfessor Zadeh is perhaps best known for inventing the concept of "Fuzzy Logic", a theory he first presented in 1965.  Fuzzy Logic is used for notions that cannot be defined in mathematical preciseness, but which rely on identifying gradations, hence the word, "fuzzy."  Applications are both endless and varied. In addition to consumer applications especially in Japanese electronics, Fuzzy Logic is being used in the fields of biomedicine, finances, geography, philosophy, ecology, agricultural processes, water treatment, satellite remote sensing, handwriting analysis, nuclear science, weather forecasting and stock market analysis, to name a few.
