Most people think that culture is something that happens to them, but what is important is that you take responsibility for culture — after all it's just a reflection of all of us, our every behavior and every action of ours.

There is something wrong with our system when I can leave here and make billions of dollars in 10 years while millions of students can’t afford to pay off their loans, let alone start a business. Look, I know a lot of entrepreneurs, and I don’t know a single person who gave up on starting a business because they might not make enough money. But I know lots of people who haven’t pursued dreams because they didn’t have a cushion to fall back on if they failed. We all know we don’t succeed just by having a good idea or working hard. We succeed by being lucky too. If I had to support my family growing up instead of having time to code, if I didn’t know I’d be fine if Facebook didn’t work out, I wouldn’t be standing here today. If we’re honest, we all know how much luck we’ve had. Every generation expands its definition of equality. Previous generations fought for the vote and civil rights. They had the New Deal and Great Society. Now it’s our time to define a new social contract for our generation. We should have a society that measures progress not just by economic metrics like GDP, but by how many of us have a role we find meaningful.

The next generation of telescopes will see millions of events per night with computers that sift through huge amounts of data. If we had had access to a computer, we would never have programmed it to look for something so unexpected. How do you pick up the things you don't know exist, the things you can't tell it to look for? My project was to study quasars, and then we accidentally stumble over these things called pulsars. They were totally unexpected, totally unknown – and it's been huge fun.

I can understand if you think that I'm disrespecting the flag by kneeling, but it is because of my utmost respect for the flag and the promise it represents that I have chosen to demonstrate in this way. When I take a knee, I am facing the flag with my full body, staring straight into the heart of our country's ultimate symbol of freedom — because I believe it is my responsibility, just as it is yours, to ensure that freedom is afforded to everyone in this country.

I want to be able to express, I want to be able to communicate, and I want to be able to understand what it is I’m doing, and I want the people whose language it is to understand what I’m doing.

As a very young singer, I was invited to the opera house in Berlin by the then-director of the opera house, Egon Seefehlner, and I had one opera to my name that I knew. He felt that there was a lot that I could learn there, which was very true, and I was so lucky to be able to have this opportunity. The thing that was happening is that I kept being offered operas that I knew that I wasn’t ready to sing, just from an experience point of view, as well as being 24 years old. So I was always asked to sing things that I thought, “Well no, I really don’t think I should sing that now. I need to sing that maybe in five years, or maybe in 10 years, but not right now. Couldn’t I please sing something else?” And that became a difficulty for me. And after being at the opera house for three years, and singing Elsa and Elisabeth — the Wagner roles that are not sort of the heavy Wagner roles — and then Mozart operas that suited my voice at the time, I was continually invited to sing things that I just felt I shouldn’t. So I took it upon myself to go to speak with the artistic director to say that I thought I should leave the opera house, and come back in some years when my maturity sort of chronologically would have caught up with the invitations that I was being offered. Of course, considering that he’d taken me into the opera house when I knew one role, he wasn’t all that happy. I thought he’d say, “Oh, what a smart girl. Oh yes, absolutely. That’s what we’ll do.” No, no. He was absolutely furious.
