Health care is a misnomer for our medical system. It should be called sick care. Doctors, hospitals and pharmaceutical companies only make money when we are in bad health. If we could instead prevent illness and disease, it would turn the entire medical system on its head and increase the quality of our lives.
The good news is that technology is on its way to letting us do this. It is now moving so rapidly that within a decade the small handheld medical reader used by Dr. Leonard McCoy in Star Trek — the tricorder — will look primitive. We are moving into an era of data-driven, crowdsourced, participatory, genomics-based medicine. Just as our bathroom scales give us instant readings of our weight, wearable devices will monitor our health and warn us when we are about to get sick. Our doctors—or their artificial intelligence replacements—will prescribe medicines or lifestyle changes based on our full medical history, holistic self, and genetic composition.
