David vs. Goliath.
I recommend this Ted Talk by Malcolm Gladwell, H/T Business Insider: There’s A Convincing Theory That Goliath, Not David, Was Actually The Underdog.
While David’s weapons were different from Goliath’s, they were just as deadly.
He also suggests that Goliath suffered from a sort of abnormal gigantism called Acromegaly. I wonder what Google’s abnormal gigantism should be called. Megalomania?
