Book excerpt: This book asks how an unconditional welcome to strangers is both challenged and made possible by new digital technologies, machine learning, and human-computer interaction (HCI). It argues that the digital – the advancement of data, the proliferation of machines (embodied or not) in our homes and on our screens, and the millions of lines of code that organize and predict our lives – is not the absence of hospitality but rather the beginning, though not without its challenges. While such an ethic remains more important than ever, The Digital Future of Hospitality updates this enduring philosophical imperative for digital times. Through the lens of cultural studies, intersectional feminism, and posthumanism, this book reanimates hospitality in relation to a series of digital texts that are relevant to the twenty-first century and beyond – android figures on television, virtual domestic assistants, home- and ride-sharing apps, wearable devices, and a renewed cultural obsession with viruses and immunity.
