You’re sitting on a balcony, scanning the news on your mobile. You tap the app of your favorite local coffee house to order your caffeinated beverage of choice. Based on your preferences, the app recommends an exotic coffee sourced from Indonesia, and you decide to try it. Ten minutes later, you hear a distinctive buzz coming towards you. You take your double latte from the drone hovering at your elbow, sip and sigh. Life is good.
