The Computational Requirements for the Matrix
goombah99 writes "Nick Bostrom discusses the computational requirements needed to simulate human existence. He offers a proof based on the anthropic principle, that you are almost certainly a computer simulation and not "real". The idea is that given that humans don't go extinct in geologically short time then eventually computer capability will allow complete simulation of the human cortex. Consequently, there must be far more simulations running in future millennia than seconds since you were born. Thus its astronomically more likely you are a simulation than real ... if humans don't go extinct shortly. Recalling the 13th floor, Robin Hanson discusses how one should try to live in a simulation. David Wolpert also weighs in on the physical limits of Turing machines for simulation of the universe. This also may explain why time travel seems impossible: we dont meet visitors from the future since only the present is being simulated."
drugs are bad mmmmkay
this article is way too deep for 3 am. i'll just wait until /. accidently reposts it sometime later this week at a more reasonable hour.
but either way, i wouldn't believe this because it would be too scary if it were true.
The episode was "Ship in a Bottle" where Moriarty and his love are sent off in a computer simulation at the end. They think it's all real, but they're really just both in a simulation of the galaxy.
At the end, Barkley wonders if he himself is part of a simulation and says "Computer, end program".
Ok, that's it. I'm a Nerd.

Its not bullet time, so much as FPS lag.
God spoke to me
For any religion that believes that we are placed here by a higher being, we essentially are living in a simulation. God created us and is now sitting back watching us run around.
One of the articles mentions ways to change one's behavior upon realization that it is all a simulation... sound familiar?
However, if everyone is a digital projection controlled by a computer program, then how is it the humans inside the matrix are capable of independent thought? Why isn't it like "Big Brother" in George Orwell's 1984, where the Thought Police were always watching for crimethink? Even if the computers' super-advanced AI engine could simulate thoughts *for* the human, and trick them into thinking they came up with it themselves, then why would the system allow a human to discover what is outside the Matrix? Is there a certain amount of "tolerance" built into the system? I guess that would explain the need for "agents."
Soo...this goes back to my initial inquiry -- where does the independent thought come from? Is it somehow hardwired to the person's brain through the matrix? If so, they need subconscious experiences (daydreams, nightmares, etc.) in order to have independent thought. So the Matrix must have had a certain level of tolerance built in.
But.... if the Matrix *was* built by a race of cruel machines designed to control humans, then why was the Matrix programmed the way it is? Are they torturing humans with a life they once knew, before AI came into play and destroyed that which they had?
All this makes me want to see "Revolutions." I hope they answer all these questions, like "Who Created The Matrix?" It's too human, too sympathetic to be built by cold, heartless machines. There is religion in the matrix, so someone had to program that in.

So I'm just a piece of code then? I bet I'm not even indented properly. Bastards!
I hope I don't get optimized away...
- you consider the world to be composed of things with surfaces and textures, yet in fact most of everything is interatomic space. Matter is a simulation.
- you consider yourself to be a being, complete and individual, yet you are built from trillions of cells each with a lifecycle, not to mention hosts of other organisms that cohabit your body, even your gene pool. Individuality is a simulation.
- you think you are reading this text, and yet it is just a sprinkling of letters and dots and random ideas. Language is a simulation, the Internet also.
- you believe you exist, and yet we are truly just temporary assemblages of matter acting as hosts for the multilevel game of life. Existence is a simulation.
But none of this means much: as in the Matrix, if I stab your simulated heart with a simulated knife, your simulated body will simulate death. And your simulated consciousness will try very, very hard to avoid that. Welcome to the Real World.
Sig for sale or rent. One previous user. Inquire within.
Cos I have a few changes I would like to make to this simulation. Simple things like
Person* Timesprout = GetPerson(xxxxx); Timesprout->physique = "Addonis";
Timesprout->attraction_level = "irristible to supermodels and actresses;'
Timesprout->wealth = BILL_GATES->wealth * 10;
Timespout->abode[0] = "Island paradise surrounded by beautiful nubile girls";
Timesprout->car[0] = "Ferrari spider";
I'll see how these work out before commiting more.
Do not try to read the dupe, thats impossible. Instead, only try to realize the truth
What truth?
There is no dupe
Slashdot linked to what Dr. Bostrom called a "Brief, popular synopsis. But read the original paper instead if you can."

Here is the original paper:

So what your saying is that if life as we know it is a simulation then the meaning of life() is Return 0;

This text roughtly assumes that the simulator is basically an american guy and the main reason for simulating a universe is to go to a party. Very deep philosophy. The simulator might well be a zen poet two centuries in the future interested in the pattern of human emotions, or some alien student trying to build the most absurd form of life. There is simply no way to know. So trying to please this simulator is completely absurd.
The talk about seeing the weaknesses in the simulation because certain parts are not simulated also takes the wrong perspective. Assuming you build a simulation that is not homogenous, you will make sure that the where there are simplifications they will have little influence (i.e they are not noticable). As for the hypothesis that certain people are not true, I don't like when people start talking about true/chosen/über/whatever people.
This is just some guy projecting his own bias on some theoretical entity and using this to justify his own (egoistic I might add) approach to live as being "logical". I agree that this is not what american society needs, but I fear it is what it wants. Of course, this has been the stuff of religions for centuries, replace simulator by god and voilà!
Trinity: Morpheus, the post was modded down, I don't know how.
Morpheus: I know, they used the overrated exploit. There's no time, you're going to have to get to another post.
Trinity: Are there any trolls?
Morpheus: Yes.
Trinity: Goddammit.
Morpheus: You have to focus, Trinity. There are mod points at Wells and Lake. You can make it.
Trinity: All right.
Morpheus: Go.
By reading this comment, you immediately waive any and all rights regarding it.
By understanding the Message of The Matrix, you will come to understand many of the logical inconsistencies in the film. Everything in that movie got put there for a reason and the W bros felt no shame altering some of the content so more people would understand the Message. So while it may ire geeks, it makes the movie easier to swallow for people new to these sorts of ideas. I personally just pretend that Morphius said, "Humans can perform up to 10^5 Teraflops (or whatever) of complex operations that the robots steal to add to their available processing power." I think you can see how this would require a much longer dialog between Neo and Morphius to inform the average viewer of what that means.
What do you think?

Godel's theorem in a nut shell: you cant prove inconsistency in any set of axioms within the context of those axioms.
suppose for a moment that this is a simulation with a finite amount of memory to parameterize the "world". the state of this system is propgated from time slice to time slice by some set of finite difference equations. well this means that everything is perfectly self-consistent. if you devise any experiment within the simulation itself to measure any observable then you will discover it is self consistent. The laws of nature a person living there would formulate would in fact be the correct ones for that system. you would never be able to discover an inconsistency.
consider for example QM. basically in a quantum world there ARE limits on resolution. indeed the limits are surprisingly like how one creates a simulation. for example, in any practical 3-D game the voxels of distant objects have larger volumes than the close by ones that you can see more clearly. likewise fast moving objects in the background are less precisely placed from frame to frame while maintaining on average an accurate speed.
its as though someone gridded the game in such a way as to have hyper cubes of constant delta-P time delta-X. hey wadda ya know that's the heisenberg uncertainty principle.
Indeed its easier to simulate a trajectory if you dont have to do it exactly. simply compute the approximate result with error bars and then any time the result is closely inspected you return a different sample from the approximate distribution. Thus one does not have to memo-ize everthing the game player has looked at carefully, you can recreate it on the fly each time something is inspected at high resolution simply by drawing an approximate sample from the distribution. The fact that two looks never quite agree is written off as the "hiesenberg uncertainty principle", or to the QM notion that inspecting an object can change its state.
Another hiesenberg principle is the energy-time uncertaintly (to measure the energy of something precisely takes increasing amounts of time). Again this is in keeping with a simulation. to compute the simulation to increacing levels of precision will take more time.
and remember folks the simulation does not have to run in real time!
Finally to digress a bit. Just suppose for moment the supposition that this is simulation is true. then might it might also be possible that the people doing the simulation are also simulations. and so on ad infinitum. the interesting thing is that at each layer of this onion it seems to me that the plausibility that you live in a simulation increases. this is because with each subsequent layer the plausibility of sufficient computer power prior to extinction improves.
