“When every single piece of media you consume is time-shifted, does that mean it's actually you that's time-shifted?”

“So I switch to my MacBook and make my rounds: news sites, blogs, tweets. I scroll back to find the conversations that happened without me during the day. When every single piece of media you consume is time-shifted, does that mean it’s actually you that’s time-shifted?”

“I've never listened to an audiobook before, and I have to say it's a totally different experience. When you read a book, the story definitely takes place in your head. When you listen, it seems to happen in a little cloud all around it, like a fuzzy knit cap pulled down over your eyes”

“Then: I google "time-series visualization" and start work on a new version of my model, thinking that maybe I can impress her with a prototype. I am really into the kind of girl you can impress with a prototype.”

“Neel cuts in: "Where'd you grow up?""Palo Alto," she says. From there to Stanford to Google: for a girl obsessed with the outer limits of human potential, Kat has stayed pretty close to home. Neel nods knowingly. "The suburban mind cannot comprehend the emergent complexity of a New York sidewalk.""I don't know about that," Kat says, narrowing her eyes. "I'm pretty good with complexity.""See, I know what you're thinking," Neel says, shaking his head."You're thinking it's just an agent-based simulation, and everybody out here follows a pretty simple set of rules"-- Kat is nodding--"and if you can figure out those rules, you can model it. You can simulate the street, then the neighborhood, then the whole city. Right?""Exactly. I mean, sure, I don't know what the rules are yet, but I could experiment and figure them out, and then it would be trivial--" "Wrong," Neel says, honking like a game-show buzzer. "You can't do it. Even if you know the rules-- and by the way, there are no rules--but even if there were, you can't model it. You know why?"My best friend and my girlfriend are sparring over simulations. I can only sit back and listen. Kat frowns. "Why?""You don't have enough memory.""Oh, come on--""Nope. You could never hold it all in memory. No computer's big enough. Not even your what's-it-called--""The Big Box.""That's the one. It's not big enough. This box--" Neel stretches out his hands, encompasses the sidewalk, the park, the streets beyond--"is bigger."The snaking crowd surges forward.”

“... nothing lasts long. We all come to life and gather allies and build empires and die, all in a single moment - maybe a single pulse of some giant processor somewhere.”
