When every device in your life is connected to the Internet (the Internet of Things), your refrigerator will schedule an oil change for your car--or something like that--and it will be amazingly wunnerful. You'll be able to lower the temperature of your home office while you're stuck in a traffic jam, while your fridge orders another jar of pickles delivered to your door.
It's all in service of convenience, the god all Americans are brainwashed to worship. Imagine the convenience of turning on the light while seated on your sofa! Mind-boggling convenience at your fingertips--and since you're already clutching your smart phone 24/7, convenience is indeed at your fingertips.
