This week, I read through a history of everything I’ve said to Alexa, and it felt a little bit like reading an old diary. Until I remembered that the things I’ve told Alexa in private are stored on an Amazon server and have possibly been read by an Amazon employee. This is all to make Alexa better, the company keeps saying. However, to many people, it’s not immediately obvious how humans interacting with your seemingly private voice commands is anything other than surveillance. Alexa, these people say, is a spy hiding in a wiretapping device.
