In early 2014, Srikanth Thirumalai met with Amazon CEO Jeff Bezos. Thirumalai, a computer scientist who'd left IBM in 2005 to head Amazon's recommendations team, had come to propose a sweeping new plan for incorporating the latest advances in artificial intelligence into his division. He arrived armed with a "six-pager." Bezos had long ago decreed that products and services proposed to him must be limited to that length, and include a speculative press release describing the finished product, service, or initiative. Now Bezos was leaning on his deputies to transform the company into an AI powerhouse. Amazon's product recommendations had been infused with AI since the company's very early days, as had areas as disparate as its shipping schedules and the robots zipping around its warehouses. But in recent years, there has been a revolution in the field; machine learning has become much more effective, especially in a supercharged form known as deep learning. It has led to dramatic gains in computer vision, speech, and natural language processing. In the early part of this decade, Amazon had yet to significantly tap these advances, but it recognized the need was urgent. This era's most critical competition would be in AI--Google, Facebook, Apple, and Microsoft were betting their companies on it--and Amazon was falling behind.

The woman in the photo seems familiar. She looks like Jennifer Aniston, the "Friends" actress, or Selena Gomez, the child star turned pop singer. But not exactly. She appears to be a celebrity, one of the beautiful people photographed outside a movie premiere or an awards show. And yet, you cannot...

Who will deliver our packages in the future -- drones, or self-driving robots? Amazon has an entire division devoted to developing drones that can carry them over the air to our doorsteps, but it also recently filed a patent on a ground-based, driverless-delivery vehicle. In so doing it joins a handful of startups and companies who are working on similarly small, self driving robots that will carry goods via the sidewalk. They're much slower than drones and they get in the way of pedestrians, but developers at thyssenkrupp Elevator think the wheeled couriers will catch on quicker than drones. Torsten Scholl, who invented the TeleRetail robot with thyssenkrupp and displayed it at the Washington Auto Show last week, says he recently took the gadget to a small village in the Swiss mountains, hoping to film it in action with a drone. Soon after he sent the drones up in the air, passers-by in the village approached him to complain, saying they "didn't want drones around here," and that the devices weren't allowed.

On Monday, a Tesla Model S slammed into the back of a stopped firetruck on the 405 freeway in Los Angeles County. The driver apparently told the fire department the car was in Autopilot mode at the time. The crash highlighted the shortcomings of the increasingly common semi-autonomous systems that l...
