Humans are incapable of securely storing high-quality cryptographic keys, and they have unacceptable speed and accuracy when performing cryptographic operations. (They are also large, expensive to maintain, difficult to manage, and they pollute the environment. It is astonishing that these devices continue to be manufactured and deployed. But they are sufficiently pervasive that we must design our protocols around their limitations.)

I'm Jewish, and my family is Jewish. I was very interested in Woody Allen when I was growing up, but I don't think of myself as a Jewish writer. I'm more from suburbia, American suburbia. I'm more from the '70s than I am from Judaism.

The sad thing about working on a movie is that you can never see the movie.

There is a lot of management going on with directing. Maybe that was the biggest surprise-just the amount of tending that I had to do. The different personalities . . . It's not my way, and it's never been my function before as a writer. I tend to be a moody and somewhat withdrawn person, and I felt very clearly that I had to throw that away because that wasn't allowed here - there were other people who were going to be filling that role. Sometimes it became exhausting, especially around the eleventh hour of the day.

I often have a theme in mind when I'm starting. I know that I want everything to be in a world of, say, evolution, or guilt.

In a lot of movies, especially big studio ones, they're not constructed in any other way than to get people to like them and then tell their friends. It's a product.

I think if I've worked anything through with screenwriting it's that I'm not going to be able to work anything through.
