For many years, the modern industry has relied upon conventional electromechanical systems. After information revolution and inventing the first digital computers, a new era has been started. Scientists and engineers utilized the computational power of digital devices to create intelligent machines which can be used in any industrial environments. For instance, labours who work in the production lines of a car factory can be replaced by intelligent robots that can operate faster with more accuracy. It is worth mentioning that the application of artificial intelligence (AI) is not limited to only industrial machines and robotic systems. This new field of computer science (i.e., AI) has threatened most of the human jobs since the main goal of AI is creating computer programs that mimic human behaviors. Therefore, the majority of jobs such as driving a taxi, operating the telephones, even cooking in restaurants can be substituted by AI algorithms or intelligent robots.
