Digital society is upon us (Lupton, 2015), and appears to have established a position in the zeitgeist of modern society. Digital society has emerged from and is expected to develop further via digitizing, big data, big data analytics, automatically logging almost all human activities and decisions made in information and communication technologies (ICT), access to online information in almost real time, artificial intelligence (AI), data-informed decision-making processes and data-driven management (Pedersen and Wilkinson, 2018). According to the contributions in this book, which are all research based, big data analytics is considered the core of the digital society. Big data analytics is a source of knowledge that creates significantly new opportunities to mobilize and allocate individuals’, organizations’ and societies’ resources more efficiently. The proponents of big data analytics promise that it is the key to making the world a better place to live in. Hospitals can treat more patients and better (Chapters 9 and 10); schools can become more efficient public institutions and pupils can attain greater well-being and higher achievements (Chapter 13); big cities can become a better place to live in (Chapter 7); green energy can be developed further and become cheaper due to smart logistics (Chapter 5); public administra-tion can become more customized and efficient (Chapter 9); and women and men can become superwomen and supermen by turning into cyborgs via wearables (Chapter 2).
