A Future Where Everything Becomes a Computer Is as Creepy as You Feared

Cars, door locks, contact lenses, clothes, toasters, refrigerators, industrial robots, fish tanks, sex toys, light bulbs, toothbrushes, motorcycle helmets -- these and other everyday objects are all on the menu for getting "smart." Hundreds of small start-ups are taking part in this trend -- known by the marketing catchphrase "the internet of things" -- but like everything else in tech, the movement is led by giants, among them Amazon, Apple and Samsung. For instance, Amazon last month showed off a microwave powered by Alexa, its voice assistant. Amazon will sell the microwave for $60, but it is also selling the chip that gives the device its smarts to other manufacturers, making Alexa connectivity a just-add-water proposition for a wide variety of home appliances, like fans and toasters and coffee makers. And this week, both Facebook and Google unveiled their own home "hub" devices that let you watch videos and perform other digital tricks by voice.
