Philip Seargeant is an applied linguist who specializes in language, social media, and online interaction. In The Emoji Revolution, Seargeant presents a wide-ranging sociolinguistic account of the historical, social, and political use contexts of emoji, arguing that emoji act “as a prism through which to view the history of human communication” (p. 5). Moreover, Seargeant identifies emoji as “a perfect cipher” (p. 190) for understanding the paradoxes of creativity and control that result from the rampant technological changes that underpin computer-mediated communication. He argues that the same innovations that make emoji a compelling global communication form—standardization, interpretive flexibility, interoperability—raise important questions about the role of consumerism and corporate power in shaping emergent computer-mediated communication practices. In this way, Seargeant identifies emoji not only as a cipher, but also as a harbinger for the future of human (and computer) communication.
