When online shoe retailer Zappos isn't paying newly trained employees to leave the company, it's replacing them entirely. Robots developed by Kiva Systems zip around a Zappos warehouse picking up items and deliver them to their meatbag underlings for packing, and then move the packages to another small group of primates where the boxes are shipped. The only problem I foresee is that the robots have wheels, so when they inevitably take over, they won't be buying any shoes from Zappos. [CNET]
