It is interesting how we associate medicine and the treatment of diseases with medication. If you ask someone about the cure of cancer, the first thing that comes in mind is a magic pill. But is not this the wrong approach? If you think about it, remedies are just chemical compounds that flow through your blood causing several effects. They'll will never do anything more significant than binding to receptors and letting the body do the work. If we want to do more advanced things it is necessary that we develop the tools to act on cellular scale, and we have almost nothing on this aspect. I feel like the field of medicine will only start to get serious after this.
