The platforms that dominate the internet wield more power than many of our nation-states. Today, Meta, Alphabet, Amazon, Apple, and Microsoft have won the favor of millions of citizens thanks to the massive use of persuasive systems that make us addicted to their services. They have managed to make our lives revolve around the five, six, or seven inches of our mobile phones and have generated a control over us that establishes them as veritable screen nations. These tech companies, with their applications, have improved our lives and offer us endless entertainment, but also—as Juan Carlos Blanco warns us—they contain a dark side that we all recognize: their business model causes a pandemic of inattention, encourages misinformation, destroys the commercial fabric of our communities, undermines our democracies, makes sectors like communications precarious, and is based on the extraction of millions of data points for advertising purposes, violating our privacy. That dream world that some young entrepreneurs from California, dressed in surf gear, announced was not what it seemed; Therefore, highlighting its most toxic effects and appealing to our responsibility to confront and even reverse the situation has become the urgent task we address here.
