Regarding governance - most ambitious politicians appear to be extroverts. I'm not an engineer but there are many in my family and they're not the most gregarious sort. Is this an inaccurate stereotype? I wonder if despite highly intelligent, moral attributes, our technologists, research scientists, etc. are not attracted to the intense social demands and / or rewards of politics. Are our smart, worthy introverts "opting out?" If so, it's a shame. But on the other hand, no-one will be coming by to tap you on the shoulder for such roles, even my neighborhood councilman has to hustle.
