Physics of the Future: How Science Will Shape Human Destiny and Our Daily Lives by the Year 2100

miniaturized to about a foot, and will eventually be as small as a cell phone. By passing one over your body, you will be able to see inside your organs. Computers will process these 3-D images and then give you a diagnosis. This probe will also be able to determine, within minutes, the presence of a wide variety of diseases, including cancer, years before a tumor forms. This probe will contain DNA chips, silicon chips that have millions of tiny sensors that can detect the presence of the telltale DNA of many diseases.
    Of course, many people hate going to the doctor. But in the future, your health will be silently and effortlessly monitored several times a day without your being aware of it. Your toilet, bathroom mirror, and clothes will have DNA chips to silently determine if you have cancer colonies of only a few hundred cells growing in your body. You will have more sensors hidden in your bathroom and clothes than are found in a modern hospital or university today. For example, simply by blowing on a mirror, the DNA for a mutated protein called p53 can be detected, which is implicated in 50 percent of all common cancers. This means that the word
tumor
will gradually disappear from the English language.
    Today, if you are in a bad car accident on a lonely road, you could easily bleed to death. But in the future, your clothes and car will automatically spring into action at the first sign of trauma, calling for an ambulance, locating your car’s position, uploading your entire medical history, all while you are unconscious. In the future, it will be difficult to die alone. Your clothes will be able to sense any irregularities in your heartbeat, breathing, and even brain waves by means of tiny chips woven into the fabric. When you get dressed, you go online.
    Today, it is possible to put a chip into a pill about the size of an aspirin, complete with a TV camera and radio. When you swallow it, the “smart pill” takes TV images of your gullet and intestines, and then radios the signals to a nearby receiver. (This gives new meaning to the slogan “Intel inside.”) In this way, doctors may be able to take pictures of a patient’s intestines and detect cancers without ever performing a colonoscopy (which involves the inconvenience of inserting a six-foot-long tube up your large intestine). Microscopic devices like these also will gradually reduce the necessity of cutting skin for surgery.
    This is only a sample of how the computer revolution will affect our health. We will discuss the revolution in medicine in much more detail in Chapters 3 and 4 , where we also discuss gene therapy, cloning, and altering the human life span.
    LIVING IN A FAIRY TALE
    Because computer intelligence will be so cheap and widespread in the environment, some futurists have commented that the future might look like something out of a fairy tale. If we have the power of the gods, then the heaven we inhabit will look like a fantasy world. The future of the Internet, for example, is to become the magic mirror of Snow White. We will say, “Mirror, mirror on the wall,” and a friendly face will emerge, allowing us to access the wisdom of the planet. We will put chips in our toys, making them intelligent, like Pinocchio, the puppet who wanted to be a real boy. Like Pocahontas, we will talk to the wind and the trees, and they will talk back. We will assume that objects are intelligent and that we can talk to them.
    Because computers will be able to locate many of the genes that control the aging process, we might be forever young like Peter Pan. We will be able to slow down and perhaps reverse the aging process, like the boys from Neverland who didn’t want to grow up. Augmented reality will give us the illusion that, like Cinderella, we can ride to fantasy balls in a royal coach and dance gracefully with a handsome prince. (But at midnight, our augmented reality glasses turn off and we return to the real world.) Because computers are revealing the genes that control our bodies, we will be able to reengineer our bodies, replacing organs and changing our appearance, even at the genetic level, like the beast in “Beauty and the Beast.”
    Some futurists have even feared that this might give rise to a return to the mysticism of the Middle Ages, when most people believed that there were invisible spirits inhabiting everything around them.

MIDCENTURY (2030 TO 2070)
    END OF MOORE’S LAW
    We have to ask: How long can this computer revolution
