The paper examines the adaption of the Nordic welfare model to changing circumstances after WW-II. The Nordic welfare model, providing generous welfare and security, is distinct from the other types of welfare state; the Liberal, Conservative-corporatist (Esping-Andersen 1990), and the later added Mediterranean welfare type and Postsocialist type (Ferrera 1996, Deacon 1993. After the expansive post-WWII period, the economic slowdown in the 1970s accompanied by problems connected with inequalities and increasing commitments in social policy, to a great extent because of population ageing, began to put pressure on the Nordic welfare states. The progress in technoscience and changed values in the new welfare culture, derived from the cultural turn and paradigm shift in social sciences and also influenced by the economic and social transformations, paved the way for rapid digital transformation and big data analytics. These changes provided possibilities to take another look at experiences of changed economic and social developments to face the new trends, risks, and needs to provide welfare and security by means of new social arrangements, such as for example redesign of the eldercare. New ways of thinking about values, have allowed the planning and implementation of social arrangements in the direction of plurality, also including privatization and informalization. Diversity is challenging universalism. The new digital and algorithmic culture, with new opportunities for utilization of the vast amount of information has been of great help in planning and decision-making, for example, in social investments. The economic recovery, together with good governance, guides transformative social policy by use of artificial intelligence in algorithmic solutions and robotism.
