Here’s a current example of the challenge we face. At the height of its power, the photography company Kodak employed more than 140,000 people and was worth $28 billion. They even invented the first digital camera. But today Kodak is bankrupt, and the new face of digital photography has become Instagram. When Instagram was sold to Facebook for a billion dollars in 2012, it employed only thirteen people. Where did all those jobs disappear to? And what happened to the wealth that all those middle-class jobs created?

Criticism is always easier than constructive solutions.

If you get deep enough, you get trapped. Stop calling yourself a user. You are being used.

People try to treat technology as an object, and it can't be. It can only be a channel.

Separation anxiety is assuaged by constant connection. Young people announce every detail of their lives on services like Twitter not to show off, but to avoid the closed door at bedtime, the empty room, the screaming vacuum of an isolated mind.

A file-sharing service and a hedge fund are essentially the same things. In both cases, there's this idea that whoever has the biggest computer can analyze everyone else to their advantage and concentrate wealth and power. It's shrinking the overall economy. I think it's the mistake of our age.

To me, to say that war isn't evil is to say that nothing is evil.
