Mozilla has long been one of the strongest champions for openness in technology -- from the software it produces to the web standards it adopts. As new technologies emerge, the battle over closed versus open systems continues to be one of the most important factors for a range of concerns that are critical to a healthy information ecosystem -- innovation, competition, privacy, security, consumer protection -- and even civil rights. With new advances in artificial intelligence -- particularly in the fields of machine learning and sensor technology -- questions of "open" versus "closed" have arisen again. However, what is becoming quickly clear is that the traditional open strategies, such as permissive licensing and code/documentation publication, may not work as well or even at all. Consider deep learning, one of the key AI techniques driving advances such as automated speech recognition.
