I never gave Google’s “Do No Evil” motto much credence, but even if Alphabet, Microsoft, OpenAI and co. are well intentioned, how do I know their technology won’t be co-opted by a differently-motivated executive board, government, or a hacker in the future? Or, in a more innocent sense, if that technology exists inside an impenetrable corporate black box, how can outsiders check the algorithm’s code to ensure that well-intentioned development is not inadvertently going off the rails?
