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.

Genetically modified organism (GMO) foods are feared and hated by environmentalists and the public alike. Yet the scientific assessment of GMOs is remarkably different. Every major scientific evaluation of GMO technology has concluded that GMOs are safe for human consumption and are a benefit to the environment.

In the digital age, we filter forward instead of filtering out. As a result, all that material is still available to us and to others to filter in their own ways, and to bring forward in other contexts.

I think that, hundreds of years from now, if people invent a technology that we haven't heard of yet, maybe a computer could turn evil. But the future is so uncertain. I don't know what's going to happen five years from now. The reason I say that I don't worry about AI turning evil is the same reason I don't worry about overpopulation on Mars.

We can't stop a baby in Africa from starving to death... but we can afford enough technology and weaponry to blow the world up a million times over.
