So I guess I'm just very worried that with Internet privacy, we're doing the same thing we're doing with medical records, is we're throwing out the baby with the bathwater, and we're not really thinking about the tremendous good that can come from people sharing information with the right people in the right ways.

I think the main thing that we need to do is just provide people choice, show them what data's being collected -- search history, location data. We're excited about incognito mode in Chrome, and doing that in more ways, just giving people more choice and more awareness of what's going on.

You carry a phone. It knows where you are. There's so much more information about you, and that's an important thing, and it makes sense why people are asking difficult questions.

We're at maybe 1% of what is possible. Despite the faster change, we're still moving slow relative to the opportunities we have. I think a lot of that is because of the negativity... Every story I read is Google vs someone else. That's boring. We should be focusing on building the things that don't exist.

I am really excited about the possibility of data also, to improve health. Imagine you had the ability to search people's medical records in the US. I imagine that would save 10,000 lives in the first year.

From a very early age, I also realized I wanted to invent things. So I became really interested in technology and also then, soon after, in business, because I figured that inventing things wasn't any good; you really had to get them out into the world and have people use them to have any effect.
