Facebook says, 'Privacy is theft,' because they're selling your lack of privacy to the advertisers who might show up one day.

In history, in most cultures, and at most points in time, if you want to find the most advanced technologies, you can look principally in two places. One is weapons and the other is musical instruments. My hypothesis is that instruments are usually ahead of weapons. In fact, I think you can find many examples of instruments being predecessors of weapons and very few in the reverse.

I have been around military technology people a lot because of my role in virtual reality I've seen weapons from conception to implementation. And there is an extraordinary gadget lust that drives the military. So it's possible that war is just the ultimate expression of creativity.

Advertisers and marketers should be looking to bring new experiences to different parts of the brain. It's a more profound idea than just dropping a billboard into a video game.

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

If you're old enough to have a job and to have a life, you use Facebook exactly as advertised, you look up old friends.

If we allow our self-congratulatory adoration of technology to distract us from our own contact with each other, then somehow the original agenda has been lost.
