We all have values that drive our choices and shape our behaviour, our work, and even our vision of the future. What sort of world do we want to see in 2050? Will we be able to avoid catastrophic climate change? Our values determine the way in which we will try to meet the challenges of the future, and dictate whether or not we will succeed. France Digitale, representing the best of the French tech sector, has gathered together a number of contributions in order to provide a challenging look on values in tech. United Tech of Europe is a collective effffort to answer some of tech and indeed humanity’s biggest questions. The contributors are all business leaders, start-up founders, venture capitalists, or tech superstars. Between them, they have founded companies worth billions of euros, and have invested billions more. It would not be an exaggeration to say that they have helped change the face of the global economy. All of them share a particular characteristic: they are value-driven, and committtted to the future of the tech ecosystem and our planet. Their views could not be more timely for those looking to challenge their thinking, fifind new perspectives, and build a prosperous and safe future on the solid foundation of strong values.
