21 st Century :Age Of Baby Face Power

Why do so many powerful people on the global scene have baby faces?  Examples include Kim Jong Eun of North Korea. He has absolute authority over 24 million North Koreans. He also has his fat fingers on ballistic missiles that have nuclear war heads. He looks like the cute Pillsbury Dough Boy or some cherub-faced bobble-headed toy. The Google founders Brin and Page also have baby faces. Facebooks Zuckerberg could be a poster boy for this new age phenomenon  A common thread of their source of power is technology. Respectively they either inherited , invented or stole someone elses invention. What makes a baby face? It's the absence of the lines of maturity. So technology has leap frogged  normal evolution and given power to the young and maybe foolish or unwise. Add central governments fiat money to technology and powerful immature people at the levers of power and a recipe for chaos appears.
