Artificial Intelligence has been debated since the term's inception. For some researchers it is important that the definition of Artificial Intelligence include only those techniques that actually reflect human cognitive processes. For others, the definition factor is that Artificial techniques are able to solve problems that would require intelligence if solved by humans, irrespective of whether the techniques employed reflect human cognition. It has also been suggested that for a definition of Artificial Intelligence to be applicable, the most important criterion is that the system can adapt to or learn from its environment ("Artificial Intelligence"). Artificial Intelligence is claimed by many to be either good or bad, but the future outcome of Artificial Intelligence will depend largely on how it is used. Work and studies in regard to and relation to Artificial Intelligence have sparked a number of opinions in the public's eyes. There are those who say that these small Artificial Intelligences are the lead way to a future where people can create machines or computer websites that can run themselves and will better human technology as a race; but others have feared that a super intelligent machine will one day become too self-aware and will together be too smart for any human mind to overcome.
Artificial Intelligence has been featured in books, movies, comics, and games, and is even finding its way into peoples' everyday lives. In practice, the term refers to a spectrum of ideas ranging from a simple system that can perform only basic tasks to a fully adaptive system that is able to solve highly complex problems by using techniques that reflect the nature of human intelligence (Schaffer). A good example would be the voice activation control on some 3G and 4G smart phones known as "Siri" and "Cortana", Artificial Intelligence that executes tasks via voice commands.
