In general governments across globe could use more pragmatic and systematic thinking that engineering offers but not at the top where different qualities as discussed in some posts above indicate...Kris
You're right, KB. The proof will be in the leadership pudding. If he does a good job, that would be fab and I'm sure a lot of people would be very happy. If he does badly, it's likely not anything to do with his engineering background and more to do with not being suited for that particular role.
It seems that Sylvie is making the assumption that only geeks choose to study engineering. What about people with leadership quality who chose to study engineering? Personally, i prefer the cream of the crop from my country's top universities to run the country, rather than a career politician or businessman who's just good at talking.
Engineering can be both constructive and destructive (9/11 terrorist had engineering backgrounds). As does politics. One can only hope that the leader/engineer uses tools that resources for the common good and applies logic and methodologies to raise the level of civility in the society he/she is asked to lead. Unfortunatly it takes more than engineering to build a 'global village'.
