Artificial Intelligence, "AI," is not a new concept, but in recent years has fueled amazing new capabilities, from sophisticated computer vision to natural language processing. Developed with enormous volumes and diversity of data and unprecedented computing power, large-scale AI systems have begun to manifest emergent---unplanned, unexpected, unexplainable---capabilities. We explore promising applications (each a sword with two-edges) and various facets of "intelligence" with an eye toward understanding the impacts of AI on culture and society.
