From predicting criminality to sexual orientation, fake and deeply flawed Artificial Intelligence (AI) is rampant. Amidst this feverishly hyped atmosphere, this book interrogates the rise and fall of AI hype, pseudoscience and snake oil. Bringing together different perspectives and voices from across disciplines and countries, it draws connections between injustices inflicted by inappropriate AI. Each chapter unpacks lazy and harmful assumptions made by developers when designing AI tools and systems, and examines the existential underpinnings of the technology itself to ask: why are there so many useless, and even dangerously flawed, AI systems?
