Imagine walking down the street to your local Starbucks. You walk to the door, and instead of a handle, there's a touchpad. The touchpad reads "Welcome [name], would you like to come inside?" It knows your name because it has NGI built-in. You push the button labeled "Yes" and walk inside the starbucks. Inside, there's a few other customers, but there are no baristas. There's a manager in the back, but he rarely comes out unless one of the touchpads gets too dirty. You walk to the bar and are met with another touchpad. It is a graphical interface for designing your beverage. You already know what buttons to push because you've used this interface many times before. After you've completed your order, the machine reads "Hey [name], do you want to pay with cash or your visa?" You press "Visa" and the machine responds "Ok thanks, I've got it on file, your order will be ready in thirty seconds." After thirty seconds, your order slides down a conveyor belt to where you're waiting, and you leave Starbucks and head to work.
