People don't appreciate that science is not an embarrassingly parallel process. Some steps have to come before others, and each of those take time. There is a ton of money being thrown at "cancer", which is a large set of incredibly complex problems. I even believe that there is never going to be "a cure for cancer", while we will be able to manage and even "cure" most types of cancer during the next two decades (IMHO). But it's a tough problem which doesn't lend itself to YC-style founder teams or extreme implementations of lean entrepreneurship.
