As a lonely teenager growing up in Virginia, I fed off any pop culture that could show me different ways of being from what I saw on 'The Cosby Show' reruns or read about in an Ann M. Martin book.

It took me years to find a program that kept me in shape: Gyms felt intimidating, and women's magazines seemed tailored for toning the bodies of already trim white women.

In America, mixed-race identity tends to invite both curiosity and suspicion, largely because few have found a way to interrogate it without centering whiteness as the scale by which to evaluate blackness.

The American understanding of China is filtered through years of politics; we rarely see the culture on its own terms.

The human family is at a critical juncture. The world is moving through a great transition. This transition is economic, as the digital revolution advances and as new powers and groups emerge.

People wanted me to do a CD-ROM of 'Hitchhiker's,' and I thought, 'No, no.' I didn't want to just sort of reverse-engineer yet another thing from a book I'd already written. I think that the digital media are interesting enough in their own right to be worth originating something in.

You get the software you pay for. In every sense. To the nth degree. That's the way the world works.
