Almost everyone who has had an idea that's somewhat revolutionary or wildly successful was first told they're insane.

If we are not trusted, we have no business.

We believe strongly that in the long term, we will be better served - as shareholders and in all other ways - by a company that does good things for the world even if we forgo some short term gains. This is an important aspect of our culture and is broadly shared within the company.

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.

We have a mantra: don't be evil, which is to do the best things we know how for our users, for our customers, for everyone. So I think if we were known for that, it would be a wonderful thing.

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.

If we were motivated by money, we would have sold the company a long time ago and ended up on a beach.
