Artificial intelligence, given its name, sounds like a computer learns everything its own. However, a set of algorithms can only become useful if there’s something to learn from: data. Dave Lee for BBC reports on a company in Kenya that supplies training data for self-driving cars:

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.

On the one hand it sounds like tedious work on the cheap, but on the other it provides people with more opportunities that were previously unavailable.
