After a night of heavy partying on New Year’s Eve, you are sound asleep.Suddenly, your wall screen lights up. A friendly, familiar face appears on the screen. It’s Molly, the softwareprogram you bought recently. Molly announces cheerily, “John, wake up. You are needed at the office. In person. It’s important.”“Now wait a minute, Molly! You’ve got to be kidding,” you grumble. “It’s New Year’s Day, and I have a hangover.What could possibly be so important anyway?”Slowly you drag yourself out of bed and reluctantly head off to the bathroom. While washing your face, hundreds ofhidden DNA and protein sensors in the mirror, toilet, and sink silently spring into action, analyzing the molecules youemit in your breath and bodily fluids, checking for the slightest hint of any disease at the molecular level.Leaving the bathroom, you wrap some wires around your head, which allow you to telepathically control your home:you mentally raise the temperature of the apartment, turn on some soothing music, tell the robotic cook in your kitchento make breakfast and brew some coffee, and order your magnetic car to leave the garage and be ready to pick you up.As you enter the kitchen, you see the mechanical arms of the robotic cook preparing eggs just the way you like them.Then you put in your contact lenses and connect to the Internet. Blinking, you see the Internet as it shines onto theretina of your eye. While drinking hot coffee, you start scanning the headlines that flash in your contact lenses.
