An investigation at the intersection of the writer and artificial intelligence, this book makes a case for the centrality and validity of the uniquely human 'writing self' against a backdrop of ubiquitous AI-generated material. With Pandora's Box irreversibly open, The Writing Self in the Age of Artificial Intelligence decodes how creative writers encounter AI, comparing AI and human-generated texts, digging into the theories and philosophies underpinning this paradigm shift towards the posthuman, and ultimately putting forward a radical manifesto for navigating creative endeavor in the future. Looking at how AI performs complex creative writing tasks, how creative writing has become commodified, and how through posthumanist, transhumanist and new materialist theories humans have become 'hackable', Paul Williams and Shelley Davidow reassert the humanness of creative endeavor by rejecting a disembodied 'subject'. Instead, they posit the need for a creative, performative, author-centered/process-writing 'self' that is changed by its own journey. Blending memoir with essay and poetry to perform the writing self they outline, the authors highlight what is unique about human creativity: serendipity, failure, synchronicity, experiential phenomenology, and what they term 'supra consciousness', a transcendent, non-hackable, innately human connected community with a shared story. Hopeful, engaging and addressing important concerns in the field, The Writing Self in the Age of Artificial Intelligence illuminates the value of writing for the writer, as a process of thinking, feeling and self-discovery.
