(WALL STREET JOURNAL) — It’s 2027, and you’re walking down the street, confident you’ll arrive at your destination even though you don’t know where it is. You may not even remember why your device is telling you to go there.

There’s a voice in your ear giving you turn-by-turn directions and, in between, prepping you for this meeting. Oh, right, you’re supposed to be interviewing a dog whisperer for your pet-psychiatry business. You arrive at the coffee shop, look around quizzically, and a woman you don’t recognize approaches. A display only you can see highlights her face and prints her name next to it in crisp block lettering, Terminator-style. Afterward, you’ll get an automatically generated transcript of everything the two of you said.

As the iPhone this week marks the 10th anniversary of its first sale, it remains one of the most successful consumer products in history. But by the time it celebrates its 20th anniversary, the “phone” concept will be entirely uprooted: That dog-whisperer scenario will be brought to you even if you don’t have an iPhone in your pocket.
