The product cycle for the Oculus Rift will be between the rapid six-month cycle of cell-phones and the slower seven-year cycle of consoles. It's rare to see a phone not coming out every year.

With the headset and motion tracker and all kinds of different future tracking technologies that we are R&Ding, there is just a huge amount of intelligence that has to be created. So we are looking at hiring some of the brightest minds out there to tackle some of those challenges and deliver the very best experience possible for the consumer.

Display companies, many of them that we've spoken to, are really excited about virtual reality because they're actually running out of innovation opportunities in other markets.

Ultimately, going into the consumer market, we really need outstanding content. That was the goal: if we can get the developer kit out at a low enough cost point, then hopefully a lot of developers would show up and start creating content.

There's a danger of some of the best people saying, 'I don't want a career in science.'

I am tired of all this sort of thing called science here... We have spent millions in that sort of thing for the last few years, and it is time it should be stopped.

If I were not a writer, I would spend more time doing the things that I am already doing, which include doing research in physics, teaching, and running a nonprofit organization with a mission to empower women in Cambodia.

I built websites for myself. I didn't want to work for anyone else. I came from a science background, so I approached things fairly analytically.
