ONE DAY SOON, as you stand in front of the bathroom mirror brushing your teeth, you may see, alongside the morning headlines, a scoreboard that ranks your household's current carbon footprint versus your neighbors'. Your electric toothbrush will beep to notify you that dutiful brushing twice a day every day for the past six months has earned you enough points for a 10 percent discount on your next checkup. You take a shower (a brief one, so as not to jeopardize your family's enviable energy-consumption score and the tax benefits it confers), get dressed and log in at your home-office computer for the morning meeting. Now that you and your co-workers appear on-screen as personalized avatars, you can answer your e-mail during meetings without appearing rude. And ever since arbitrary sales quotas were replaced with personalized “life meters” (which swell on-screen to reflect real-time, positive feedback from your clients), you've felt more purpose and ownership over your daily tasks. It's going to be a great day.
