I was growing up in Hyesan, right by the closest North Korea-China border. China was just across the river: you could see across. So I was curious. On the river, on both sides, you have houses, then mountains. I wanted to know what was on the other side of the Chinese mountains.

When I was growing up, my mum was doing illegal smuggling with China. Sometimes she would see a fortune teller for advice. One time I went with her: 'In your future, you'll be living in foreign country and eating the foreign country rice,' she said.

Certainly in North Korea, man is always superior to woman. Even the government treats women horribly. What is the slogan? Woman is a flower.

Staying in China provided me with the opportunity to adjust to life outside of North Korea and to gain a sense of perspective, most importantly, by learning that so much of what I had been taught about my country was a lie.

I realized immediately that this was a terribly important discovery, but I didn't realize how important it would be until we had spent a lot of time in the laboratory studying it.

I built websites for myself. I didn't want to work for anyone else. I came from a science background, so I approached things fairly analytically.

As a science-fiction writer, I feel my responsibility is to look ahead and see the dangers of what might happen and try to warn people of the potential pitfalls.

All people who grew up with science fiction and fantasy and horror went through the whole acculturation process of the genre. We were all told to read the golden age writers. We were all told Heinlein and Asimov and all these straight, white males, although some of them were Jewish.
