This does reinforce my idea that medical technology and research is advancing at an exponential pace, faster than the evolution of diseases can keep up. A treatment for type I diabetes seemed to be impossible. A diabetic's pancreas betrays them and begins killing the cells that produce insulin. There's no pill or surgery that can stop that, nothing short of reprogramming pancreatic cells. And yet, here is a promising sign of a cure! It's really amazing, and the future probably holds even more legitimate medical wonders. We might be the one of first generations to live to 100+ on average.
Type I diabetes is expensive, ~$5,000/yr without insurance. Anyone with this diabetes would probably be willing to pay any amount less than that every year for the rest of their lives in exchange for this treatment. Talk about customer lock-in! Most of the controversy over stem cells has been centered around federal funding, but treatments for chronic and costly diseases will pay for themselves several times over. For now I can only hope that this research advances fast enough to help everyone who is currently dependent on insulin.
