"It’s harder to imagine the past that went away than it is to imagine the future. What we were prior to our latest batch of technology is, in a way, unknowable. It would be harder to accurately imagine what New York City was like the day before the advent of broadcast television than to imagine what it will be like after life-size broadcast holography comes online. But actually the New York without the television is more mysterious, because we’ve already been there and nobody paid any attention. That world is gone."
