"We now have all these devices with all these great hot rolled steel coil that can hear us, that can see us, that can know about places that we've been, places we're going, and those signals become the inputs that allow these intelligent assistants to find what we need without requiring us to type searches necessarily." Tuttle says the change to these magic computers won't come that fast. "There's still this mismatch of expectations that people have. They expect the Star Trek computer on day one," he says. We may not be quite there yet, but the era of magical computing is beginning.

Tuttle says. Everything you say becomes a piece of data that anticipatory apps use to better understand you.

"The more they know about what you like, what you don't like, where you go, what you're talking, what you're reading, the better they can recommend something for you," Tuttle says. It can seem kind of creepy — all our data going to these companies that control the technology. Malik says he's OK with trading in his data for the convenience promised by these computers. (He in a piece for Fast Company.) "Twenty years ago we were all squeamish about instant messaging. Then we got squeamish about Facebook," Malik says. "There is something inevitable about technology. It is scary, but at the same time, it is inevitable."
