This collection of excerpts introduces the concept of LikeWar, a new form of conflict where social media blurs the lines between war and peace, making individuals potential targets and transforming online interactions into a new battlespace. The authors illustrate this through examples ranging from gang violence in Chicago and the Islamic State's viral marketing campaigns to Russian disinformation efforts and the manipulation of information during elections. The text explores the historical evolution of communication technologies, from the telegraph to the smartphone, and how the rise of social media has led to information inundation, the spread of fake news, and the potential for algorithmic manipulation. It also highlights the challenges faced by social media companies in moderating content and the importance of media literacy in navigating this new digital landscape.
