Mehran Sahami, a Stanford professor and former Google employee, wants to see a reset from the technology industry. For the past few decades, the world's technologists (many of whom become its corporate executives and venture capitalists) have been taught to prioritize optimization and efficiency without thinking a whole lot about ethics. The result has been stunning corporate success but significant costs to society. Sahami argues that regulation can certainly help right the balance. But he also believes that tech company leaders and employees can shift their mindsets and practices to ensure they're serving the greater good, not just themselves. He's the coauthor, along with Rob Reich and Jeremy Weinstein, of "System Error: Where Big Tech Went Wrong and How We Can Reboot."
