If I were Mark Zuckerberg or any of these guys, I would say, "My God. How does the world expect us to deal with this?" I mean, it's too big a responsibility; I think they're going to welcome this.

We are learning that the earth functions like an invisible organism. We are the various cells of one living being. Those who work to save the earth are its antibodies.

The American public is not aware that there might be potential allergenic and toxic reactions. With regular food, at least people know which foods they have an allergy to.

How do we address network neutrality when the whole world is connected? How do we ensure governments don't purloin this for political purposes? It's already happening.
