FOMO (Fear of Missing Out) refers to an increasingly widespread syndrome: the fear of missing out on any seemingly important news in our digitally overloaded society. Social media and its mechanisms of influence have become overpowering. Individuals can no longer escape their pressures. Manfred Poser has intensely examined the alarming manifestations of this highly problematic social development and highlights the dimensions that dependence on smartphones, tablets, or computers has reached in most countries. If there is not a collective awakening and a radical shift in direction, the digitally saturated society, down to the smallest details of life, will sink into a chaos of anonymity and automation. A warning of utmost social relevance.
