Steve Jobs was one of the first people to understand that the computer wasn't just a tool, but that it could be an extension of ourselves, and he positioned Apple that way. The iPod was this revolutionary device with the idea of 1,000 songs in your pocket, and then that machine represents who you are.

Jobs would have ever have asserted that Bill Gates was not serious about technology. He was a huge pioneer in that world, albeit doing something quite different in approach from what Steve did. He was dismissive of Gates' foundation work as something he did to make himself feel better.

I feel that Julian Assange came to be both paranoid and self-regarding in ways that ultimately undermined his own mission.

In a busy world, even as information is moving so rapidly, we have to learn who to trust in that regard even as we ourselves have to become more critical of the people who we want to trust. It's a weird situation.

I'm still an Apple person, but let's just say the magic aura is gone. In a way that was a sad thing to lose, but I feel better for it. It's just a machine now, not linked with any greater mission or mystique.

If people are portrayed as monsters, we become disconnected from them, and to me that is not remotely interesting.

The sex abuse crisis in the Catholic Church is the result of what police call "noble cause corruption," the belief that because you are dedicated to doing good, you can do no wrong.
