Nowadays, we remark that breakthroughs in the field of Artificial Intelligence (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 (due to multiplicity of elements, brilliant successes, and senseless failures at the same time). In some cases, misunderstanding about AI led to hype, firing, and rude criticism even among many senior experts of the AI domain. Therefore, we detected the need for a short and very comprehensive overview of the whole and very vast AI field (as a good and useful reference) for providing fast insights eading to a better contextual understanding.
