There's been spying for years, there's been surveillance for years, and so forth, I'm not going to pass judgement on that, it's the nature of our society.

For those who say you're thinking too big... be smart enough not to listen. For those who say the odds are too small ... be dumb enough to give it a shot. And for those who ask, how can you do that?... look them in the eyes and say, I'll figure it out.

The Internet is fast becoming a cesspool where false information thrives.

In general in technology, if you own a platform that's valuable, you can monetize it.

I think it's pretty clear that the internet as a whole has not had a strong notion of identity. And identity means, 'Who am I?' Fundamentally, what Facebook has done has built a way to figure out who people are...

We know where you are. We know where you've been. We can more or less know what you're thinking about.
