Question every assumption and go towards the problem, like the way they flew to the moon. We should have more moon shots and flights to the moon in areas of societal importance.

I have a strong disrespect for authority and for rules. Including gravity. Gravity sucks.

I have a really deep belief that we create technologies to empower ourselves. We've invented a lot of technology that just makes us all faster and better, and I'm generally a big fan of this. I just want to make sure that this technology stays subservient to people. People are the number one entity there is on this planet.

Every time I act on a fear, I feel disappointed in myself. I have a lot of fear. If I can quit all fear in my life and all guilt, then I tend to be much, much more living up to my standards. I've never seen a person fail if they didn't fear failure.

The Jetsons had them in the 1960s. They were the defining element of 'Knight Rider' in the 1980s: cars that drive themselves. Self-driving cars appear in countless science fiction movies. By Hollywood standards, they are so normal we don't even notice them. But in real life, they still don't exist. What if you could buy one today?

In 50 years, there will be only 10 institutions in the world delivering higher education and Udacity has a shot at being one of them.

I'm really looking forward to a time when generations after us look back and say how ridiculous it was that humans were driving cars.
