California's would-be governor prepares for battle against job-killing robots

The graduating computer science students at UC Berkeley had just finished chuckling at a joke about fleets of "Google buses, Facebook shuttles and Uber-copters" lining up to whisk them them to elite jobs in Silicon Valley. The commencement ceremony for a cohort of students who, one professor confided, were worth around $25bn, was a feel-good affair. Until, that is, Gavin Newsom took to the lectern and burst the bubble. The smooth-talking Democrat, and frontrunner to win California's gubernatorial race next year, warned the students that the "plumbing of the world is radically changing". The tech industry that would make them rich, Newsom declared, was also rendering millions of other people's jobs obsolete and fueling enormous disparities in wealth.
