Robot dogs are here. But why?

You might think you already know Spot, the robot dog from Boston Dynamics. Maybe you saw a viral video of it opening a door, or dragging a truck, or dancing. But now, this robot has hit a HUGE milestone… Spot got a job! These robots are now out in the real world doing real work, for fire departments, factories, defunct nuclear power plants like Fukushima, ancient ruins like Pompeii, deep mines, and, more controversially, police departments. You might already be starting to see robot dogs walking around, and even if you’re not, they’re starting to affect your life.
