Just last night I was editing a chapter in the new book that involves real-time mimicking of human beings by computers. One premise is, by using everything that’s known about you and your friends through surveillance systems, this technology could effectively stand-in for all of you. We could all become informers without our knowledge or consent, by unwittingly carrying on private e-mail, text-message, telephone or (someday soon) video conversations with such an interactive program.

Then this morning I see this. No, it’s not perfect, but I’m pretty sure you’ll be impressed. Maybe even a little freaked out.
