Artificial intelligence (AI) is simulating human brain by computer systems. It combines computer science and datasets, to enable problem-solving and decision-making capabilities of the human mind. During the last decade, this technology has attracted lots of attention because it has been rapidly developed and applied to so many areas of human activities. It could respond to so many of daily questions efficiently, and also, perform tasks and duties that would require human intelligence, such as learning, reasoning, perception and problem-solving. AI technology can process large amount of data and these days is being used across different businesses and industries. Some of the advantages of AI are: ability to analyze data accurately and rapidly, promoting efficiency and productivity, save time, advise in different activities, such as management, finance, banking, marketing, health, transportation, and security affairs. Of course AI has some disadvantages, such as: job displacements, ethical concerns about people privacy, biased programming, accelerated hacking, terrorism, destroying cyber security, misuse of personal data and biometric information. In order to avoid the negative consequences of artificial intelligence, AI should be developed and used in an ethical manner. Different countries and global institutions should try to combine its scientific capacity with ethical norms and principles effectively.
