Computer miracle

When Artificial Intelligence works as intended, Silicon Valley types often say it's "like magic".
But it isn't magic. It's Brenda, a 26-year-old single mother who lives Kibera, Africa's largest slum, and perhaps the toughest neighbourhood on earth, where hundreds of thousands of people live in a space not too much bigger than London's Hyde Park.
Each day, Brenda leaves her home here to catch a bus to the east side of Nairobi where she, along with more than 1,000 colleagues in the same building, work hard on a side of artificial intelligence we hear little about - and see even less.
In her eight-hour shift, she creates training data. Information - images, most often - prepared in a way that computers can understand. Brenda loads up an image, and then uses the mouse to trace around just about everything. People, cars, road signs, lane markings - even the sky, specifying whether it's cloudy or bright. Ingesting millions of these images into an artificial intelligence system means a self-driving car, to use one example, can begin to "recognise" those objects in the real world. The more data, the supposedly smarter the machine. She and her colleagues sit close - often too close - to their monitors, zooming in on the images to make sure not a single pixel is tagged incorrectly. Their work will be checked by a superior, who will send it back if it's not up to scratch. For the fastest, most accurate trainers, the honour of having your name up on one of the many TV screens around the office. And the most popular perk of all: shopping vouchers.

Brenda does this work for Samasource, a San Francisco-based company that counts Google, Microsoft, Salesforce and Yahoo among its clients. Most of these firms don't like to discuss the exact nature of their work with Samasource - as it is often for future projects - but it can be said that the information prepared here forms a crucial part of some of Silicon Valley's biggest and most famous efforts in AI. Being a data training expert is boring, repetitive, never-ending work. And when not in front of our cameras, some staff talked about how they faced pressure to work quickly in order to hit company targets, leading to fewer breaks. Some Samasource workers are freelancers who can work anywhere, but with a webcam watching them as they work.

 Samasource provides a living wage of around $9 a day. That's an improvement, but still a pittance for Silicon Valley.

"Yes, it's cost effective," Janah said. "But one thing that's critical in our line of work is to not pay wages that would distort local labour markets. If we were to pay people substantially more than that, we would throw everything off. That would have a potentially negative impact on the cost of housing, the cost of food in the communities in which our workers thrive"
