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.

You have to combine both things: invention and innovation focus, plus the company that can commercialize things and get them to people.

I feel like my job as CEO is always to be pushing people ahead.

The amazing thing is that we're part of people's daily lives, like brushing their teeth. It's just something they do throughout the day while working, buying things, deciding what to do after work and much more. Google has been accepted as part of people's lives.

We chose it because we deal with huge amounts of data. Besides, it sounds really cool.

Artificial intelligence would be the ultimate version of Google. The ultimate search engine that would understand everything on the Web. It would understand exactly what you wanted, and it would give you the right thing. We're nowhere near doing that now. However, we can get incrementally closer to that, and that is basically what we work on.

Most of us carry at least one device, all the time, every day. In fact many of us would feel naked without our smartphone. It's hardly surprising mobile search queries - and mobile commerce - are growing dramatically across the world.
