Self-driving cars will enable car-sharing even in spread-out suburbs. A car will come to you just when you need it. And when you are done with it, the car will just drive away, so you won't even have to look for parking.

I've developed my passion for cars that drive themselves from being stuck in traffic for many, many, many hours of my life. I don't know what it adds up to, but I feel like I've lost a year or two just in traffic. That's big to me. That's a lot of time, a lot of money that I just lose on the road.

I have been spending the better part of my professional life trying to create self-driving cars. At Google, I am working with a world-class team of engineers to turn science fiction into reality.

At the end of the day, the true value proposition of education is employment.

That's what Google taught me. Aim higher. Udacity is my playground - to radically experiment and find out. I've seen the light.

If we study learning as a data science, we can reverse engineer the human brain and tailor learning techniques to maximize the chances of student success. This is the biggest revolution that could happen in education, turning it into a data-driven science, and not such a medieval set of rumors professors tend to carry on.
