In Nepal, I realized a certain part of my spiritual search had come to an end. I wasn't ever going to live in a Himalayan cave (I like electricity and a soft bed way too much), and I sure wasn't going to find enlightenment so easily.

I was really interested in this ability for others to create virtual memories for us. In "The Cartographers" I explore this through Adam Woods, and the company he works for, which produces virtual memories that people can beam into their consciousness. While the technology is sci-fi, the story is also a metaphor for the way love relationships create memories in our minds.

[George W.] Bush's presidency was one of the great nightmares of my life to date.

I think the future is intrinsically linked with our universal human problems. In fact, it's these very problems, and how we deal with them, which will determine our future.

I came across an old story of mine that I'd written a decade ago. The main joke of the story is that a mother is telling her children about how she met their father online. The majority of memories the mother has all have to do with really funny links he sent her, a music download that she loved, etc. - and because of these superficial details she fell in love with the father. Reading it today, it's hardly a dystopian story; it's simply a realistic story about how people actually meet.

"Moksha" is really a satire of myself. I've always been interested in Eastern spirituality. I'm particularly interested in enlightenment and the spiritual pursuit to liberate ourselves (I'm a Buddhist at heart). During my teenage years, I imagined I'd end up going to India to become a yogi; study with the last living saints in a cave; give up all my worldly possessions; learn to levitate. And there's still part of me that can see myself "disappearing" for some years at an ashram somewhere.

However, in my fiction, I want to give an even further warning of where we're heading. And so, in "Heartland," you have people selling off their topsoil, and an underwater oil spill that has lasted over three-hundred days.
