"It's an increasingly common scene as companies from Amazon to Little Caesars and Uber introduce more ways to go about daily tasks while avoiding face-to-face contact," USA Today's Katharine Lackey writes in a front-pager:

• "Uber is testing self-driving cars in a handful of cities."
• "Amazon opened an automated grocery store late last year, still in beta testing, where customers (currently only its employees) can grab items and go ... All that's needed is a smartphone, which tracks the items carted out the door."
• "Little Caesars unveiled The Pizza Portal, a machine that lets you buy and grab your pie without a cashier."
• Why it matters: "As technology leaves out the human element, some worry that we're 'walling ourselves off.'"
