John Etchemendy and Fei-Fei Li are the codirectors of Stanford’s Institute for Human-Centered Artificial Intelligence (HAI), founded in 2019 to “advance AI research, education, policy and practice to improve the human condition.” In this interview, they delve into the origins of the technology, its promise, and its potential threats. They also discuss what AI should be used for, where it should not be deployed, and why we as a society should—cautiously—embrace it.
