Heck, we may have even already found the cure for cancer or such. If you think about it, it would only take one person to give the opportunity to one other person, and if everybody does it, think about what could happen.
I am not sure, the medial scientific community is very corrupted. I.e. they get free holidays in order to accept certain medicines etc; In fact, most of the scientific research is locked away from society by corporations. For example, try to access ACM, you will find you have to pay for almost every article - but this money does not go to the scientists. An american (aaron swartz) tried to make a lot of information available to the public, he was charged with many years in prison for it and is now dead.

yes, a single person can change the world altogether, both in the positive and negative sense.
