Computing is kind of a mess. Your computer doesn't know where you are. It doesn't know what you're doing. It doesn't know what you know.

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.

You're probably on the right track if you feel like a sidewalk worm during a rainstorm.

If you ask an economist what’s driven economic growth, it’s been major advances in things that mattered - the mechanization of farming, mass manufacturing, things like that. The problem is, our society is not organized around doing that.

Our goal is long-term growth in revenue and absolute profit - so we invest aggressively in future innovation while tightly managing our short-term costs.

We should be building great things that don't exist.

The "Be good" concept also comes up when we design our products. We want them to have positive social effects.
