“Marketplace Tech” host Molly Wood dropped by to tell us about the major tech trends of the past decade. If the 2000s were about the growth of the internet, the 2010s were about learning how to use it. Software saw a boom, with the rise of apps like Uber and platforms like Facebook. Molly’s big prediction? By 2030, phones will be no longer. Plus: the trade deficit in goods shrank for the third straight month, California’s new data privacy law kicks in at the start of the new year and a nurse navigates finances in her semiretirement.
