So far, Amazon hasn’t sold its worker-monitoring software to other companies—and some industry watchers believe it never will. But Amazon’s cloud division in recent years started selling tools designed to automate real-world tasks, including some developed for its e-commerce and logistics operation. Last year, Amazon Web Services announced a suite of products to monitor equipment and factory lines, supplementing or even replacing human workers. Companies as varied as Capital One, Labcorp and GE Appliances use Amazon Connect call-center software, which deploys artificial intelligence tools to make human agents more productive and automate some customer interactions entirely.
