Sure, I agree, I wasn't trying to say that it's the politician's job...that line was meant to represent the ethical sphere of a human's existence, another example of a facet in which I don't think a scientist necessarily should be trusted to lead, at least not solely based on their occupation/skill set related to their scientific work. That's all I meant.
I don't want to step on too many toes, but I have to make mention of the error in the particular arrogance among the scientific community that their work qualifies them to reform other industries and facets of the human existence. Obviously the work of scientists and engineers is vital, and worthy of credit and praise, but I would not trust even the smartest scientists and engineers I know to handle the foreign policy of a nation, for example. Or tell me how to live my life, ethically or morally. I'm saying this from the perspective of an engineer, to my credit--I'm well aware of the talent and brilliance in the community. I just think it's dangerous to worship the altar of science to solve all of our problems.
