On the side of a dusty Jakarta road, nestled in the corner of a gas station, might be the future of coffee. Driving home, you might preorder a cup as you plan to refill the car, even before pulling up to the gas station. Open the Kopi Kenangan app, click on "preorder," and choose one -- perhaps a mellow coffee with just a hint of acidity, creamy with milk. By the time you arrive at the station, the iced coffee, made by a human, will be sitting on the countertop, sweating in a plastic cup in the Jakarta humidity. Indonesian coffee chain Kopi Kenangan -- "coffee memories" in Bahasa Indonesia -- did not set out to be a tech-powered coffee chain.
