Yet that's essentially what Amazon has been doing to millions of us with its assistant Alexa in microphone-equipped Echo speakers. And it's hardly alone: Bugging our homes is Silicon Valley's next frontier.
Many smart-speaker owners don't realize it, but Amazon keeps a copy of everything Alexa records after it hears its name. Apple's Siri, and until recently Google's Assistant, by default also keep recordings to help train their artificial intelligence.
So come with me on an unwelcome walk down memory lane. I listened to four years of my Alexa archive and found thousands of fragments of my life: spaghetti-timer requests, joking houseguests and random snippets of "Downton Abbey." There were even sensitive conversations that somehow triggered Alexa's "wake word" to start recording, including my family discussing medication and a friend conducting a business deal.
