I think you're making that mistake a lot of people in medicine make and what separates them from the tech industry. They're huge pessimists because they don't grok things like physics or computing and are trained/selected for their ability to pass tests out of a textbook. If you put your geekdom "crawl entire web/robot car/computers on every desk" hat on you'll realize you can run circles around the current medical industry.

edit: I get you're trying to give advice. If I make the claims less exciting no-one will bother. If too exciting, they think unfeasible. Getting the balance right seems hard.
