Every message we send travels through a vast physical system: routers, cell towers, data centers, power grids, and miles of undersea and terrestrial fiber networks. And every part of it depends on human decisions. On the next episode of Fiat Lux Redux, Tuesday, August 4 at 9 AM, Nicole Starosielski, professor of Film and Media at UC Berkeley, discusses how the future internet requires more than just computer scientists and engineers—it demands policymakers, economists, marine biologists, urban planners, and journalists. To bridge this gap, she launched UC Berkeley’s Global Digital Infrastructure (GDI) program and certificate, creating a multidisciplinary field to train future leaders to navigate the complex physical systems that support our digital infrastructure. Starosielski discusses the myth of the ‘wireless cloud’ and the real-world vulnerabilities and complex human decisions around physical infrastructure, including the controversial construction of data centers.
