Engineering Out Loud

Imagine the camera of a self-driving car switches to a power-saving mode and takes low-resolution images. As a result, the car hits a pedestrian. A mundane decision to save battery thus becomes a decision to value battery life over human life. While we have long relied on software and automation, the prospect of a fully automated decision process charges many algorithmic decisions with a variety o...
