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.

Books about technology start-ups have a pattern. First, there's the grand vision of the founders, then the heroic journey of producing new worlds from all-night coding and caffeine abuse, and finally, the grand finale: immense wealth and secular sainthood. Let's call it the Jobs Narrative.

Technology has changed almost everything. One institution remains stubbornly anchored in the past. It's where I work - the United States Congress, a 19th Century institution using 20th Century technology to respond to 21st Century problems.

The government needs to invest in raising digital fluency of its citizenry.

I am so sorry to see the state of reading in such decline. I think it says something really scary and terrible about us as a culture. I think it does have to do with everyone's total global embrace of technology.
