Growing up, I was often put under a lot of pressure. Being an athlete, I've been dealing with pressure for a long time.

I won the 2011 Visa Championships, the 2012 Pacific Rims, and then the 2013 American Cup (the first and only senior elite competition of my elite career).

My back is permanently messed up.

By 2012, I probably had, like, three stress reactions in my back. Two stress fractures in my fibula.

The idea that Google, Yahoo, and eBay are getting a free ride is absolutely unfair criticism. We have to build out our own infrastructure. And we have to inter-connect to the public Internet.

Why did Google, for example, recently decide to offer free 411 service? I haven't talked to people at Google, but it's pretty clear to me why. It's because of speech recognition. It has nothing to do with 411 service: it has to do with getting a database of voices, so they don't have to license speech technology from Nuance or someone else.

The Internet is so big that no one can control anything, really.

It's going to be interesting to see how society deals with artificial intelligence, but it will definitely be cool.
