Nowadays, we remark that breakthroughs in the field of AI suggesting its similarity with human beings, tremendous diversity of subfields and terminologies implied in the AI discipline, huge diversity of AI techniques, mistakes of AI and hype could lead to confusion about a clear understanding of the field. In some cases, misunderstanding about AI led to hype, firing, and rude criticism even among many senior experts of the AI domain. In this paper, we proposed a “Comprehensive Overview of Artificial Intelligence (AI)” so that everyone (starting with newbies) is able, via clear insights, to make a difference rapidly. As a contribution to scientific literature, we unambiguously showed via carefully designed illustrations how the AI realm is held by well-known Theories of Intelligence and related AI Concepts that perfectly match the current technological advances in the field. And, of course, we provided a clear insight into Ethical concerns about Artificial Intelligence.
