I see three forces militating in favor of growing inequality: increasing measurement of worker value added, automation through smart software, and globalization.

Look at electricity in human history - it took a few decades for electricity to really revolutionize the American economy. And the Internet will be the same. At some point in the future, we will arrive at a new era of low-hanging fruit.

When you look at the actual data on technological innovation, one thing you see is that what I call the 'low-hanging fruit' has been exhausted. So radio, flush toilets, electricity, and automobiles - a lot of very basic inventions - have spread to almost all households.

The iPhone is made on a global scale, and it blends computers, the Internet, communications, and artificial intelligence in one blockbuster, game-changing innovation. It reflects so many of the things that our contemporary world is good at - indeed, great at.

If atheism solved all human woe, then the Soviet Union would have been an empire of joy and dancing bunnies instead of the land of corpses.

Reading is exercise for our brains in the guise of pleasure. Books give us insight into other people, other cultures. They make us laugh. They make us think. If they are really good, they make us believe that we are better for having read them.

My philosophy is, involve your family in whatever you do. Nothing gives you more joy.

There is a difference between happiness and wisdom: he that thinks himself the happiest man is really so; but he that thinks himself the wisest is generally the greatest fool.
