The transition to Industry 4.0, and the subsequent ubiquitous digitalization and integration of artificial intelligence (AI) into the economic system, has set the stage for a fundamental change - one towards forming a cyber economy: a type of economy in which humans are economic subjects who interact with or are confronted with AI. This book examines these interactions and specifically analyzes the overall effects of digitalization on the workplace, and on the economic system of the future. Scholars from a diverse range of fields address both the challenges and opportunities of using AI in business sectors, as well as the role of people dealing with digital channels. In closing, the book discusses the need to, and options for, training and educating the labor force in the digital age.
