All We Are Is Pixels in the Wind



Sometimes I think scientists are there for the sole purpose of dreaming up new ways to freak me out and keep me up at night.You could say that's a little narcissistic of me; you could also argue, however, the equally valid possibility that scientists are little more than mini-bosses in the Shigeru Miyamoto-esque eight-bit side scroller that is my life.

I got some interesting feedback from last week's story about Second Life getting all up in real life's grill, one message of which being a link to this story in the New York Times, highlighting some of the life work of Dr. Nick Bostrom. Dr. Bostrom, director of the Future of Humanity Institute as well as a philosophy professor at Oxford University, has some very interesting ideas about the future of humanity; more interesting still are his ideas on how the future may be effecting us now, looping back like an infinite technological paradox. You see, Bostrom has a theory that, in the future, advanced "posthumans" will be big fans of games like Civilization played out with sentient characters on computers with the capacity for untold amounts of AI, and baby, somewhere out there the future is now and we're already living it.

Until I talked to Nick Bostrom, a philosopher at Oxford University, it never occurred to me that our universe might be somebody else’s hobby. I hadn’t imagined that the omniscient, omnipotent creator of the heavens and earth could be an advanced version of a guy who spends his weekends building model railroads or overseeing video-game worlds like the Sims.

But now it seems quite possible. In fact, if you accept a pretty reasonable assumption of Dr. Bostrom’s, it is almost a mathematical certainty that we are living in someone else’s computer simulation.



In Bostrom's eleven-page theory (published in Philosophical Quarterly) he proposes an equation that looks something like this:

fsim = fpNH/(fpNH)+H



and what it basically breaks down to is that at least one of the following must theoretically be true:

a.) Mankind will never reach a state of advanced technological wizardry required for artificial-intelligence civilization simulations en masse.
b.) Mankind will reach such a state, but will have evolved to a point where they have better things to do than run civilization sims.
c.) Mankind will and has already reached such a state, and the reality we exist in now is that of a computer-generated simulation.

Just so we're clear, we aren't talking about something like The Matrix, where one could feasibly wake up and unplug himself from the simulation system; Bostrom's hypothesis is somewhere more between the lines of Tron and a futuristic World of Warcraft, millions of cognizant little worlds at the fingertips of millions of would-be gods.

Bostrom's thesis is, if anything, very well thought-out, exploring every facet of this world of possibilities from the cognizant disparity of "characters" to the truly chilling notion that this game is a first-person platform and all of your friends and lovers are, for all intents and purposes, Hylian villagers:

In addition to ancestor-simulations, one may also consider the possibility of more selective simulations that include only a small group of humans or a single individual. The rest of humanity would then be zombies or "shadow-people" -- humans simulated only at a level sufficient for the fully simulated people not to notice anything suspicious. It is not clear how much cheaper shadow-people would be to simulate than real people. It is not even obvious that it is possible for an entity to behave indistinguishably from a real human and yet lack conscious experience. Even if there are such selective simulations, you should not think that you are in one of them unless you think they are much more numerous than complete simulations. There would have to be about 100 billion times as many "me-simulations" (simulations of the life of only a single mind) as there are ancestor-simulations in order for most simulated persons to be in me-simulations.



I have half a mind to say, "Yes well, anything's possible," but the other half wants to squint at everyone in search of Koopa Troopa tendencies.

The application of math equations to try and inject logic into the visceral nature of the human experience will probably strike me as somewhat incompatible and insufficient no matter what, but what is truly interesting about the whole argument is its modern theological nature: a flesh-and-blood god to manage our imaginary belief-states, fill in the details of our world, create miracles through save games, and roll stats for a nation of millions. Still more interesting is the approach with which this theory is given: it's not so much about injecting doubt into the unquestionable truth of our existence, but more of an alternate explanation, not something to slow us down but just to take in as information and possible use as the base of a new religion. (A simple task, I'm sure, when being told that we are all pawns in someone's game of World of Warcraft Expansion Pack 100.)

A more practical question is how to behave in a computer simulation. Your first impulse might be to say nothing matters anymore because nothing’s real. But just because your neural circuits are made of silicon (or whatever posthumans would use in their computers) instead of carbon doesn’t mean your feelings are any less real.

David J. Chalmers, a philosopher at the Australian National University, says Dr. Bostrom’s simulation hypothesis isn’t a cause for skepticism, but simply a different metaphysical explanation of our world. Whatever you’re touching now — a sheet of paper, a keyboard, a coffee mug — is real to you even if it’s created on a computer circuit rather than fashioned out of wood, plastic or clay. You still have the desire to live as long as you can in this virtual world — and in any simulated afterlife that the designer of this world might bestow on you.



So, I suppose that's that: you keep on keepin' on, whether substantive or someone else's Sim. I guess that's all one really can do, isn't it? What do you think?

Now, if you'll excuse me, I must be going. All this mithril I found in my neighbors' dresser drawers and flower pots isn't just going to spend itself.


If you found this interesting, I recommend picking up Jostein Gaarder's Sophie's World. Similar themes, on a somewhat more luddite level. Hat tip to Tony_T for the link!

A lot like the ol' "brain in a vat" thought experiment. I think it's all generally called solipsism.

+1 - I used to have a cheat for SimCity that gave me unlimited $$ - anyone figure that code out yet? biggrin



In the sims 2 type control shift g? i think and then type in "motherlode" in the little box that comes up. it gives you 50,000 simoleans each time biggrin

Here's a nifty little short story on the subject.

Edit: Well... closely related to the subject.

I think so. Not to say there isn't a lot of interesting stuff suggested in this theory, but a lot of it seems to be at the core a kind of rephrasing of basic ontological solipsism. The key difference seems to be that Descartes reached his "brain in a vat" supposition by applying the methodology of radical skepticism, while Bostrom, just the opposite, posits his version of solipsism as a mathematical certainty.

Since this is my simulation, I have to congratulate all of you artificial shadow players for making it so interesting to me.

Yeah, as I was reading this article, I had a flashback of a scene from Animal House.

What if the ai sims, developed ai sims to entertain themselves?

Clones of clones? That would explain our seemingly limitless capacity for stupidity.

But if this guy is right, that would finally explain why my master's thesis director always seemed like a badly coded non playing character from a cheap WoW clone.



Pretty much the brain in a vat argument, with a slight difference: no actual brain. The typical brain in vat argument results in a scenario such as that in The Matrix. This argument results in more of a The Thirteenth Floor kind of thing.
