Information and communication technology, relying on the internet or not, has profoundly changed our society, and will probably continue to do so to ever greater extents. Technology brings progress, human flourishing, the fading of social and political borders between states, new freedoms to be ourselves individually and collectively, greater access to emancipatory knowledge. It also greatly shifts power away from the structures we had known for centuries and for which our institutional setups were designed. It entrenches certain fault lines and exacerbates certain inequalities. It changes how we make war, how we do business, how we interconnect. It is one of the elements that truly mark our today and will define our tomorrow. We need to understand these changes, what their promises and threats really are beyond knee-jerk hype, how they are regulated and by whom, and what law and in particular international law can and perhaps should do. This course will review these questions in areas such as artificial intelligence, censorship, personal data and other new currencies, cyberattacks and cybersecurity, online and algorithmic dispute resolution, competition and taxation, copyright and patents in the digital age, and the regulation of the Internet itself. No prior knowledge is required. Students in disciplines other than law are welcome.
