With the expansion in the sphere and scale of human activities triggered by globalization, artificial intelligence (AI) constitutes the future of mankind. Unlike traditional hardware or software, artificial intelligence tries to emulate human intelligence in a non-human body by taking decisions without human guidance. They serve our various needs and in turn require the least amount of effort or energy from our end. As the science and technology of Artificial Intelligence is developing, smart artifacts are already being deployed as we speak (You may already have heard about Google's'DeepMind', IBM's'Watson' or Tesla's autopilot system in their electric cars in the news). The future highlights an important fact: AI will become more general, more capable and more efficient than a large group of humans in a very short period of time.
