The internet economy has produced digital platforms of enormous economic and social significance. These platforms—specifically, Google, Facebook, Amazon, Twitter, and Apple—now play central roles in how millions of Americans obtain information, spend their money, communicate with fellow citizens, and earn their livelihoods. Their reach is also felt globally, extending to many countries around the world. They have amassed the economic, social, and political influence that very few private entities have ever obtained previously. Accordingly, they demand careful consideration from American policymakers, who should soberly assess whether the nation’s current laws and regulatory institutions are adequately equipped to protect Americans against potential abuses by platform companies.

The Program on Democracy and the Internet at Stanford University convened a working group in January 2020 to consider the scale, scope, and power exhibited by the digital platforms, study the potential harms they cause, and, if appropriate, recommend remedial policies. The group included a diverse and interdisciplinary group of scholars, some of whom had spent many years dealing with antitrust and technology issues.

ANTITRUST AND PRIVACY CONCERNS are two of the most high-profile topics on the tech policy agenda. Checks and balances to counteract the power of companies such as Google, Amazon, and Facebook are under consideration in Congress, though a polarized political environment is a hindrance. But a domestic approach to tech policy will be insufficient, as the users of the large American tech companies are predominantly outside the United States. We need to point the way toward a transnational policy effort that puts democratic principles and basic human rights above the commercial interests of these private companies.

These issues are central to the eight-week Stanford University course, “Technology and the 2020 Election: How Silicon Valley Technologies Affect Elections and Shape Democracy.” The joint class for Stanford students and Stanford’s Continuing Studies Community enrolls a cross-generational population of more than 400 students from around the world.

POPULAR CULTURE HAS ENVISIONED SOCIETIES of intelligent machines for generations, with Alan Turing notably foreseeing the need for a test to distinguish machines from humans in 1950. Now, advances in artificial intelligence that promise to make creating convincing fake multimedia content like video, images, or audio relatively easy for many. Unfortunately, this will include sophisticated bots with supercharged self-improvement abilities that are capable of generating more dynamic fakes than anything seen before.

In our paper “How Relevant is the Turing Test in the Age of Sophisbots,” we argue that society is on the brink of an AI-driven technology that can simulate many of the most important hallmarks of human behavior. As the variety and scale of these so called “deepfakes” expands, they will likely be able to simulate human behavior so effectively and they will operate in such a dynamic manner that they will increasingly pass Turing’s test. 

THE EMERGENCE OF A DIGITAL SPHERE where public debate takes place raises profound questions about the connection between online information and polarization, echo chambers, and filter bubbles. Does the information ecosystem created by social media companies support the conditions necessary for a healthy democracy? Is it different from other media? These are particularly urgent questions as the United States approaches a contentious 2020 election during the COVID-19 pandemic.

The influence of technology and AI-curated information on America’s democratic process is being examined in the eight-week Stanford University course, “Technology and the 2020 Election: How Silicon Valley Technologies Affect Elections and Shape Democracy.” This issue brief focuses on the class session on “Echo Chambers, Filter Bubbles, and Polarization,” with guest experts Joan Donovan and Joshua Tucker.

THE 2020 ELECTION IN THE UNITED STATES will take place on November 3 in the midst of a global pandemic, economic downturn, social unrest, political polarization, and a sudden shift in the balance of power in the U.S Supreme Court. On top of these issues, the technological layer impacting the public debate, as well as the electoral process itself, may well determine the election outcome. The eight-week Stanford University course, “Technology and the 2020 Election: How Silicon Valley Technologies Affect Elections and Shape Democracy,” examines the influence of technology on America’s democratic process, revealing how digital technologies are shaping the public debate and the election.
