Latinofuturism describes a broad range of Latina/o speculative aesthetics and an emerging field of study. In addition to referencing a broad spectrum of speculative texts produced by Chicana/os, Puerto Ricans, Dominican Americans, Cuban Americans, and other Latin American immigrant populations, Latinofuturism also includes innovative cultural productions stemming from hybrid and fluid borderlands spaces such as the US–Mexico border. The umbrella genre of speculative fiction (SF), moreover, indexes the companion genres of science fiction (sci-fi), horror, and fantasy. Instead of approaching these genres separately, SF recognizes the ways in which these genres overlap, blend, and mutually inform one another. As Shelley Streeby notes, the umbrella genre of the speculative is especially useful in analyzing Latinofuturist texts that self-consciously appropriate and blend genres in a manner evocative of the mestizaje animating Latina/o culture. The broader category of SF further enables us to unearth, remap, and focalize how Latina/os have contributed to sci-fi, fantasy, and horror, as well as related subgenres. Through employing the speculative, Latinofuturist texts articulate a grammar of the subjunctive, daring to ask and imagine, “what if?” Latinofuturism builds upon Catherine Ramírez’s foundational prism of Chicanafuturism, which denotes cultural production that redeploys the technological in relation to cultural identity, and, in doing so, interrogates and effaces boundaries between primitive and modern, the past, present, and future, as well as the human and non-human. Propelling Latinofuturism is the disordering aesthetic of rasquachismo, a working-class Chicana/o sensibility of creative recycling or making do. Latinofuturist writers and artists do not passively consume received forms of the speculative, but instead creatively repurpose them toward emancipatory ends. In addition, Latinofuturism draws inspiration from Afrofuturism, as articulated by scholars such as Mark Dery, Alondra Nelson, and Ytasha Womack. Whereas Afrofuturism foregrounds the African diaspora and the legacy of slavery in regard to new media and the technological, Latinofuturism focuses on migrations within and across the Americas and beyond. Prevalent themes in Latinofuturism include indigenismo, mestizaje, and coloniality, which operate to question narratives of progress and technological advancement as well as to render more radical visions of the future. However, as Isabel Millán argues, Afrofuturism and Latinofuturism become tightly knit when considering Afro-Latina/o speculative productions. More broadly, Latinofuturism must be also situated within US ethnic and global subaltern futurisms as the experiences of people of color in the United States and throughout the world are interwoven through histories of bodily and epistemological violences systematically omitted from narratives of progress and technological advancement. Importantly, Latinofuturism, along with other ethnic futurisms, share a radical reimagining of a collective future that blurs colonial binaries, making collective space to imagine and enact otherwise.
