In the information age, telecommunications is the pillar of a strong economy. To developing countries, restructuring this industry is a necessary step toward integration into the world economy. Restructuring telecommunications, therefore, has been a pervasive issue in the economic reform programs of many countries in recent years. However, the nature of these changes has varied widely among these nations. "Unfinished Business" examines the process of reform in Mexico and contrasts it with that of the United States, Brazil, and New Zealand, examining both the economic and technological aspects of this highly complex situation.

Using interviews with key players in the policy process, Mariscal provides a detailed analysis of key elements and figures. Her multidisciplinary perspective allows for a full exploration of the international differences in telecommunications restructuring. Going beyond simply asking why privatization and deregulation policies were successfully implemented in Mexico, the work offers a comprehensive guide to the process and impact of policy choices on telecommunications development.

The hidden costs of artificial intelligence—from natural resources and labor to privacy, equality, and freedom.

What happens when artificial intelligence saturates political life and depletes the planet? How is AI shaping our understanding of ourselves and our societies? Drawing on more than a decade of research, award‑winning scholar Kate Crawford reveals how AI is a technology of extraction: from the minerals drawn from the earth to the labor pulled from low-wage information workers to the data taken from every action and expression.

Crawford reveals how this planetary network is fueling a shift toward undemocratic governance and increased inequity. Rather than taking a narrow focus on code and algorithms, Crawford offers us a material and political perspective on what it takes to make AI and how it centralizes power. This is an urgent account of what is at stake as technology companies use artificial intelligence to reshape the world.
