I've never heard of a leader who wasn't sure he was smarter than everyone else and therefore entitled to force his ideas on everyone else.
Except for the Founding Fathers, who deliberately created a limited government with a Bill of Rights, and George Washington who, incredibly, turned down an offer of dictatorship.
There are many remarkable leaders throughout history and around the world who have done the best that they could for the people they found themselves leading lead and did so for noble reasons and not because they felt like they were better than them.
Tecumseh, Malcolm X, Angela Merkel, Cincinnatus, Eisenhower, and Gandhi all come to mind.
George Washington was surely an exceptional leader but he isn't the only one.
I still think they'd come to their senses. I mean, it's somewhat tautological, you can't control something that's smarter than humans.
Though that said, the other problem is capitalism. Investors won't be so face to face with the consequences, but they'll demand their ROI. If the CEO plays it too conservatively, the investors will replace them with someone less cautious.
