The Atlantic: “…Cynics of every age suspect their virtual assistants of eavesdropping, and not without reason. Smart speakers are yet another way for companies to keep tabs on our searches and purchases. Their microphones listen even when you’re not interacting with them, because they have to be able to hear their “wake word,” the command that snaps them to attention and puts them at your service. By 2021, there will be almost as many personal-assistant bots on the planet as people. The speakers’ manufacturers promise that only speech that follows the wake word is archived in the cloud, and Amazon and Google, at least, make deleting those exchanges easy enough. Nonetheless, every so often weird glitches occur, like the time Alexa recorded a family’s private conversation without their having said the wake word and emailed the recording to an acquaintance on their contacts list. Amazon explained that Alexa must have been awakened by a word that sounded like Alexa (Texas? A Lexus? Praxis?), then misconstrued elements of the ensuing conversation as a series of commands. The explanation did not make me feel much better. Privacy concerns have not stopped the march of these devices into our homes, however. Amazon doesn’t disclose exact figures, but when I asked how many Echo devices have been sold, a spokeswoman said “tens of millions.”

By the end of last year, more than 40 million smart speakers had been installed worldwide, according to Canalys, a technology-research firm. Based on current sales, Canalys estimates that this figure will reach 100 million by the end of this year. According to a 2018 report by National Public Radio and Edison Research, 8 million Americans own three or more smart speakers, suggesting that they feel the need to always have one within earshot. By 2021, according to another research firm, Ovum, there will be almost as many voice-activated assistants on the planet as people. It took about 30 years for mobile phones to outnumber humans. Alexa and her ilk may get there in less than half that time…”
