Jobs in retail, transportation, manufacturing, and agriculture are highly vulnerable to technological change. Retailers such as Macy’s and The Limited are closing hundreds of stores and cutting tens of thousands of jobs as people buy more and more products online, and others are testing robotic assistants or planning for autonomous stores. Over 33 companies are now working on autonomous vehicles, which will soon replace transport jobs. Robots have probably taken about 85% of the 5 million manufacturing jobs that have disappeared from the United States since 2000. Automated farming is also quickly advancing.
