Estimates vary, but by 2020 there could be over 30 billion devices connected to the Internet. Once dumb, they will have smartened up thanks to sensors and other technologies embedded in them and, thanks to your machines, your life will quite literally have gone online.
The implications are revolutionary. Your smart refrigerator will keep an inventory of food items, noting when they go bad. Your smart thermostat will learn your habits and adjust the temperature to your liking. Smart lights will illuminate dangerous parking garages, even as they keep an “eye” out for suspicious activity.
