I never realized Amazon's automated checkout technology was just an outsourced, creepy, Mechanical Turk:
"Though it seemed completely automated, Just Walk Out relied on more than 1,000 people in India watching and labeling videos to ensure accurate checkouts. The cashiers were simply moved off-site, and they watched you as you shopped."

Gérard G. Medioni is a Vice President and Distinguished Scientist at Amazon. He is also an Emeritus Professor of Computer Science at the University of Southern California, where he served as Chairman of the Computer Science Department from 2001 to 2007. Medioni, whose research interests span a broad spectrum of the image understanding field, joined Amazon in 2014 to help create Just Walk Out technology, a system which employs cameras and sensors to allow customers to take the items they want from shelves and leave a store without waiting in line to check out. More recently, he helped create the identity service Amazon One, a convenient, contactless way for people to use the palm of their hand for payment, age verification, loyalty, entry and more.
