Since totaling my car in an accident last December, my eagerness to get a self-driving car has only accelerated. Here’s an interesting look at the training data used to train these AIs and who generates them.

Autonomous cars are only as good as the human drivers they learn from — so the people who teach these systems how to drive need to be excellent drivers themselves. To get a look at what it takes to do this job, Bloomberg Technology’s Aki Ito recently joined two vehicle operators who work for self-driving car startup Aurora Innovation Inc. on a test drive in the chaos of downtown San Francisco. This is an episode of Next Jobs, a mini-documentary series about careers of the future.

Here’s an interesting look at “Data Labelers” and how cheap human labor could once again be China’s competitive advantage.

In order to avoid plowing into other cars or making illegal lane changes, they need a lot of help. In China, that help is increasingly coming from rooms full of college students. Li Zhenwei is a data labeler. His job, which didn’t even exist a few years ago, involves sitting at a computer, clicking frame-by-frame through endless hours of dashcam footage, and drawing lines over each photo to help the computer recognize lane markers.
