YOU WAKE UP refreshed. Ever since you got that alarm clock that adapts to your sleep cycle, your calendar, and the traffic report, you practically leap out of bed. You exercise, focusing on the muscles that the biometric sensor in your shirt says need some help. Not 10 seconds after you finish, the oven beeps—breakfast is ready. Healthy stuff. You need it, after all the drinking last weekend. As you eat, the TV streams headlines tailored to your interests. Suddenly, your smartwatch buzzes with an alert: Pileup on the freeway. You need to leave, like now, or you're going to be late to work. You have that presentation today. You can't be late.
