The rate of innovation in emerging technologies, particularly Artificial Intelligence (AI) and social computing, is shaping the IT landscape at a revolutionary pace. This is a systematic review of the literature in terms of a detailed examination of three major themes: seamless integration of AI with mainstream IT systems, ethical considerations of such integration, and social computing trends. The review to the forefront that AI integration, in addition to delivering unprecedented enhancement in performance, function, and security, also ushers in complex technical and ethical issues that compel a paradigmatic shift to hybrid models, aggressive data governance, and human-centered design. Further, advances in social computing are not merely facilitating human-to-human connection but are actually tapping into collective intelligence and transforming the very essence of digital sociality. The paper underscores interdependence of the fields and confirms IT technological innovation is successful if developed on an integrated platform where innovation and wise application coexist with ongoing optimization and close understanding of human-computer interaction. New concepts and future research after the present article are expected based on this extensive literature review, hoping to inform future inquiry and applications in the fast-evolving IT industry.
