IF YOU ARE AMONG THE YOUNG AT HEART:

 America could be on the threshold of its greatest century.

With new drilling technologies, the United States will soon have an energy surplus. This means trillions of dollars in new wealth and a foreign policy not dominated by oil.

Given advances in agriculture and bioengineering, America could be the Saudi Arabia of grain in a century when the world is clamoring for more food. Wireless communication, artificial intelligence and rapid advances in life sciences are transforming every facet of American business and daily life. Entire classes of diseases are on the verge of being eradicated by manipulating individual molecules on the surfaces of living cells.

Technological innovation means that in the coming decades, driverless vehicles will flawlessly move people and products on our highways, never getting lost, never having accidents. The development of 3D printing machines is racing ahead--and they will be down-scaled for home use, so that consumers can instantly create thousands of objects at the touch of a button.

This country is younger than all other industrialized nations, and if we get immigration right, we're going to stay young.
