Technology has served a recurrent role as a utopian imaginary for speculative fiction writers and consumers. As a utopian promise, technology appears to provide individuals, communities, and whole societies with the means to overcome nature – whether it is base human natures, relationships with one’s environment, or the perceived limitations of one’s body. This chapter focuses on two similar technological fantasies, James Cameron’s Terminator films and Martha Wells’ Murderbot series. In both series, central figures – namely the T-800 played by Arnold Schwarzenegger and Murderbot – approximate being human but are limited by their technological being. Yet, in being not-fully-human, they expose how technology always serves as a false utopian promise: there is no way out of our humanness through technology. In this way, technological fantasies serve as a form of horror, at once tempting readers with possibilities, but revealing those possibilities to be empty – or malignant.
