As president and co-founder of the Center for Humane Technology, Tristan Harris devotes his time to contemplating ways technology can be more humane. In 2013, Harris, who was a design ethicist at Google, created a presentation called “A Call to Minimize Distraction & Respect Users’ Attention.” The presentation went viral and led to two Ted Talks and a 60 Minutes interview that sparked a movement. His podcasts, courses, research, and toolkits are designed to help people reclaim their attention in the face of tools that are engineered to distract.
