"We will live in a game!" This is what you will take away after watching Jesse Schell's presentation at DICE 2010 summit. He envisions a day that has normal activities, like brushing your teeth, eating cereals, watch TV, etc, but which will let you win points and benefits when attending to those activities.
Great fun to watch the presentation, very intriguing and eye opening at the same time. Read about it via IEEE Spectrum.
