During his lecture at Singularity University, Hillis explained how scientific medicine is beginning to revert back to more ancient, ayurvedic lessons about healthcare. The approach is to treat the body as a system, where balance is the foundation for good health and disease and sickness are the externalities of imbalance. With advancements in proteomics and computing we can begin creating models of what a healthy bodily state looks like. In the same way we might use environmental models to analyze the global climate, we can isolate specific variables that can inform the larger picture. As the data piles up, preventative medicine will become a quantitative endeavour. Hillis believes the doctors visit of the future will be a simple blood test that measures proteins, lipids and some other key signals, which can then be plugged into a systematic database to help us treat diseases long before any symptoms arise. It is a huge upgrade in efficiency, one that could save millions of lives and alleviate the indebted healthcare system in the process.
