People are fascinated, for whatever reason, by human drama, and the idea that cameras are capturing ambient stories.

I'm fascinated by artificial intelligence.

In terms of long-term durable storage, the human mind, paradoxically, is pretty good, but it's very fragile.

I'd grown up in the U.K., where the surveillance apparatus went into place in the 1970s in response to the Troubles with the IRA. When I was a kid, we moved to Chicago, and I was surprised to see you could live in a large city in which you didn't have cameras on every street corner.

Look at anyone's bookcase at home, no matter how modest, and you're going to find a book that contains wisdom or ideas or a language that's at least a thousand years old. And the idea that humans have created a mechanism to time travel, to hurl ideas into the future, it sort of bookends. Books are a time machine.

But I have been interested in dreams, really since I was a kid. I have always been fascinated by the idea that your mind, when you are asleep, can create a world in a dream and you are perceiving it as though it really existed.
