We're losing track of the vastness of the potential for computer science. We really have to revive the beautiful intellectual joy of it, as opposed to the business potential.

If you love a medium made of software, there's a danger that you will become entrapped in someone else's recent careless thoughts. Struggle against that.

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.

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.

People accept ideas presented in technological form that would be abhorrent in any other forms
