Here, 19 esteemed scholars from around the world tackle the topic from different angles. Manuel Castells, David Gelernter, Juan Ignacio Vázquez, Evgeni Morozov, Mikko Hyppönen, Yochai Benkler, Federico Casalegno, David Crystal, Lucien Engelen, Patrik Wikström, Peter Hirshberg, Paul DiMaggio and Edward Castronova address such matters as the "Internet of things"; the sociology of the Internet; cybercrime and Internet security; the future of work; the Internet and urban-rural sustainability; the "Worldstream and the Cybersphere"; gaming and society; the Internet’s influence on languages and new economic systems; the massive changes wrought by the net in the music industry; and other aspects of its many cultural, social and political ramifications.
