Serving our end users is at the heart of what we do and remains our number one priority.

Optimism is important. You have to be a little silly about the goals you are going to set. There is a phrase I learned in college called, 'having a healthy disregard for the impossible.' That is a really good phrase. You should try to do things that most people would not do.

I like going to Burning Man, for example. That's an environment where people can try out different things. I think as technologists we should have some safe places where we can try out some new things and figure out what is the effect on society, what's the effect on people, without having to deploy kind of into the normal world.

Especially in technology, we need revolutionary change, not incremental change.

If you say you want to automate cars and save people's lives, the skills you need for that aren't taught in any particular discipline. I know - I was interested in working on automating cars when I was a Ph.D. student in 1995.

Sergey and I founded Google because we're super optimisitc about the potential for technology to make the world a better place. Think about how many people are underserved by transportation today, like those with disabilities, and how self driving cars will transform their lives. Or the wasted time you sit in your car every day commuting to and from work. Or the deaths and injuries that could be avoided.

Technology should do the hard work, so you can get on and live your life. We're only at one percent of what's possible, and we're moving slow relative to the opportunity we have.
