Virtual Reality is going to be an important technology. I am pretty confident about this.

By giving people the power to share, we're making the world more transparent.

I got my first computer in the 6th grade or so. As soon as I got it, I was interested in finding out how it worked and how the programs worked and then figuring out how to write programs at just deeper and deeper levels within the system.

The real question for me is, do people have the tools that they need in order to make those decisions well? And I think that it's actually really important that Facebook continually makes it easier and easier to make those decisions... If people feel like they don't have control over how they're sharing things, then we're failing them.

If people want change, then they will find a way to get that change. So, whatever technology they may or may not have used was neither a necessary nor sufficient case for getting to the outcome that they got to, but having people who wanted change was.

In my experience everyone will have a different view of the right level of tax so governments need to provide clear guidance that conforms to a set of international standards that all governments accept.

If a product costs $10,000 or $20,000 it has limited use. This is what the first computers cost! Only when almost everyone is able to afford it will it be a real thing.
