Liz Shuler was standing inside a university lab one day a few years ago when she saw the future of everything — in a cutting board.

At the time Shuler was secretary-treasurer of the AFL-CIO, one of America’s most storied labor organizations, and she’d come to Pittsburgh’s Carnegie Mellon University with a delegation that included members of Unite Here, the union representing hundreds of thousands of workers in the hospitality industry. Their mission: to get a glimpse at how technology might impact the workplace in the years ahead. It didn’t take long before that impact became clear, at least in the kitchen. One of the professors at CMU, a school known for its prowess in technology and design, was demonstrating a cutting-edge cutting board that was able to measure how fast someone sliced vegetables, as well as the quality of their motion.
