Having been bullied growing up, it's something that's really near and dear to my heart. You probably won't have many friends on Snapchat if you're being a jerk.

I feel like I'm finally learning how to use Twitter, and Tweetbot has been a huge part of that. The interface is awesome, and it lets me easily manage two accounts at once.

Five years ago, we came to the realization that the camera can be used for more than capturing memories. We showed it can be used for talking. The dream for us is expanding the camera and what it can do for your life. It has capabilities beyond making memories.

Deep-learning will transform every single industry. Healthcare and transportation will be transformed by deep-learning. I want to live in an AI-powered society. When anyone goes to see a doctor, I want AI to help that doctor provide higher quality and lower cost medical service. I want every five-year-old to have a personalised tutor.

Children who use the Internet are much better informed than when I was young. Use this to your advantage.
