I'm hoping the reader can see that artificial intelligence is better understood as a belief system instead of a technology.

In fact, one reason I am interested in developing things in virtual reality is that they're so fascinating. I can come up with problems that are harder than warfare to take up people's time.

Advertisers are not thinking radically enough - they look for technology to lead instead of trying the neuroscience approach and thinking about what parts of the brain haven't been activated before. These new experiences bring new capabilities to the brain.

When you have a global mush, people lose their identity, they become pseudonyms, they have no investment and no consequence in what they do.

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?

The most effective young Facebook users, however -- the ones who will probably be winners if Facebook turns out to be a model of the future they will inhabit as adults -- are the ones who create successful online fictions about themselves.

I'm not in any sense anti-Facebook.
