Popular Stanford computer science professor and alum Mehran Sahami discusses his new book System Error: Where Big Tech Went Wrong and How We Can Reboot (authored with fellow Stanford professors Rob Reich, MA ’98, PhD ’98, and Jeremy Weinstein). In an age of technological despondency and hyperfixation on optimization, Sahami presents an outline for a course correction that would allow big tech to support and uplift—not hinder—our democracy and fundamental values.
