At its very core, virtual reality is about being freed from the limitations of actual reality. Carrying your virtual reality with you, and being able to jump into it whenever and wherever you want, qualitatively changes the experience for the better. Experiencing mobile VR is like when you first tried a decent desktop VR experience.

You need virtual reality to understand high level science or high level math. It's very helpful to explain third and fourth dimensional things that people are constantly addressing in quantum physics. But, as soon as you're creating an avatar, and you can live and you can start to feel sensations on VR, that has gone too far.

Virtual reality is the 'ultimate empathy machine.' These experiences are more than documentaries. They're opportunities to walk a mile in someone else's shoes.

Obviously, virtual reality is where I've placed my bet about the future and where the excitement is going. At this point, I could say it's almost a lock. It's going to be magical - it is magical - and great things are coming from that. Along the way, I was focused on the first-person shooters. I said we should go do something on mobile.

Virtual reality is already affecting people on an emotional level much more than any other media, and it has the potential to scale: all you need is an attachment for your cellphone, and you can have this experience.

When people take off the headset, they immediately have a creative idea about what they can make in virtual reality, and a lot of them immediately want to get involved.

When I saw how real virtual reality can be, and that we can replace human vision with virtual vision, this can be the ultimate platform.

I'd really love to work with virtual reality at some point. You could make a killer adventure game with that.

Crucial to science education is hands-on involvement: showing, not just telling; real experiments and field trips and not just 'virtual reality.'

I started looking at small companies that were running a sort of virtual reality cottage industry: I had imagined that I would just put on a helmet and be somewhere else - that's your dream of what it's going to be.

Virtual reality sort of encloses and immerses the person into an experience that can be really cool but probably has a lower commercial interest over time. Less people will be interested in that, but there are some really cool areas there for education and gaming that we have a lot of interest in.

Language for me narrates the pictures in my mind. When I work on designing livestock equipment I can test run that equipment in my head like 3-D virtual reality. In fact, when I was in college I used to think that everybody was able to do that.

The telephone is virtual reality in that you can meet with someone as if you are together, at least for the auditory sense.

I'm excited about Augmented Reality because unlike Virtual Reality, which closes the world out, AR allows individuals to be present in the world but hopefully allows an improvement on what's happening presently.

It connects humans to other humans in a profound way that I've never seen before in any other form of media. And it can change people's perception of each other. And that's how I think virtual reality has the potential to actually change the world.

Virtual reality is a technology that could actually allow you to connect on a real human level, soul-to-soul, regardless of where you are in the world.

One of my friends started a company in 1997, seven years before Facebook, called SocialNet. And they had all these ideas, and you could be, like, a cat, and I'd be a dog on the Internet, and we'd have this virtual reality, and we would just not be ourselves. That didn't work because reality always works better than any fake version of it.

I like live audiences, with real people - virtual reality is no substitute.

Photography is a kind of virtual reality, and it helps if you can create the illusion of being in an interesting world.

Virtual reality and augmented reality will change the way we shop.
