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 interested in art, and I think about the process of making art. It's part of my personality, my experience of the world, so it ends up in the movies. It's where my head is.

The way I write is very much without kind of a goal. I have something I'm interested in and then I decide I'm going to explore it. I don't know where the characters are going to go, I don't know what the movie is going to do or what the screenplay is going to do. For me, that's the way to keep it alive.

I don't write genre stuff in any form. I'm not interested in it. I always try to do the opposite of that.

We try to organize the world, which isn't organized the way our brains want to organize it. We tell stories about the people in our lives, we project ideas onto them. We project relationships with people, we make our lives into stories. I don't think we can avoid doing that.

I can talk endlessly about characters, or why someone did this or that, and what that dynamic and interaction is. I really love it, and I think that actors really respond positively to the fact that I like to talk about that stuff, because I'm not sure that all directors do.

The conventional wisdom is - people say this all the time - you should only write something when you're far enough away from it that you can have a perspective. But that's not true. That's a story that you're telling. The truth of it is here, right now. It's the only truth that we ever know. And I'm interested in that truth and the confusion being part of the experience and sorting it your way through and figuring it out.
