Robots are taking our jobs: John Deere unveils self-driving tractor

In rural areas, where workers are scarce because young people are moving to cities, autonomy may hold the key to sustaining sufficient yields. Farmers can control the tractors via a smartphone app, of course. You can start the machine with the swipe of a button, then watch live video as the tractor moves across the field from a pair of boxes that contain 12 stereo cameras and an Nvidia GPU. Theoretically, the tractors can be operated remotely from anywhere in the world.
