Which of the possible futures might be a good future, and how do we know? Stephanie Bender looks at contemporary films and novels to address major ethical challenges of the future: the ecological catastrophe, digitalisation and biotechnology. She proposes that fiction and its modes of aesthetic simulation and emotional engagement offer a different way of knowing and judging possible futures. From a critical posthumanist angle, she discusses works ranging from Don DeLillo's Zero K (2017) and Margaret Atwood's MaddAddam Trilogy (2003-2013) to Kim Stanley Robinson's New York 2140, Avatar (2009), and Blade Runner 2049 (2017) among many others.
