Are we living in a simulation?

>A technologically mature “posthuman” civilization would have enormous computing power. Based on this empirical fact, the simulation argument shows that at least one of the following propositions is true: (1) The fraction of human-level civilizations that reach a posthuman stage is very close to zero; (2) The fraction of posthuman civilizations that are interested in running ancestor-simulations is very close to zero; (3) The fraction of all people with our kind of experiences that are living in a simulation is very close to one.

>If (1) is true, then we will almost certainly go extinct before reaching posthumanity. If (2) is true, then there must be a strong convergence among the courses of advanced civilizations so that virtually none contains any relatively wealthy individuals who desire to run ancestor-simulations and are free to do so. If (3) is true, then we almost certainly live in a simulation. In the dark forest of our current ignorance, it seems sensible to apportion one’s credence roughly evenly between (1), (2), and (3).

Too lazy to read 14 pages? This is a good summary:

These speculations are on par with onthological arguments..
unfalsifiable and pointless..

>unfalsifiable
Did you even read the paper?

Enormous computing power doesn't prove that such a simulation is possible.

Even if P->(XYZ), so long as P is not proven true, then XYZ doesn't matter.

Think of it like this:

If the christian god made the world, then Jesus is most certainly his son and he is the only way to salvation; therefor, we ought to worship Jesus.

These people are not focusing on proving P because they are worthless.

One can consider a sequence of possible situations in which an increasing fraction of all people live in simulations: 98%, 99%, 99.9%, 99.9999%, and so on.

As one approaches the limiting case in which everybody is in a simulation (from which one can deductively infer that one is in a simulation oneself), it is plausible to require that the credence one assigns to being in a simulation gradually approach the limiting case of complete certainty in a matching manner.

If this was a simulation, don't you think we'd have flying cars and jetpacks at the very least?

We'll get there.

Not enough wood and gold.

yes. and all that quantum magic is just a bug in the simulation.

How do we know our reality is how reality should be? This world could fake and gay, from a "simulator's" perspective. Maybe physics doesn't make any sense, except to us since this is how we're programmed.

This is theoretically impossible. To simulate the universe you need computer as big as universe.

Stopped reading there.

This whole ((((theory)))) is nothing but presenting wild statements as facts to prove something that is ultimately entirely meaningless.

Probably not. It is impossible to simulate our quantum universe with a classical computer. Even quantum computer would have to be many times the size of the universe, because nature is continuous and not based on binary qubits.

Quantum mechanics is very hard to simulate, much harder than classical physics. Nature does not care about computational efficiency at all and in fact goes out of its way to "waste computations" at the drop of a hat.

That is not something that would be expected if the universe is a computer simulation.

Makes sense. That is why my computer is the size of Azeroth.

>A technologically mature “posthuman” civilization would have enormous computing power. Based on this empirical fact

It's not about the "size" of virtual world. It's about the amount of data that describe the state of this world. To describe a single bit of dust you need as many data as millions of Azeroths

You need to understand that computers has physical limitations. You need physical matter to store and data.
Event if we manage to store data in a subatomic particles, we still need thousands of that particles to store data about one real particle.

if we're living in a simulation howcome my life is so bad?

Who cares? It has no bearing upon our existence.

its a nightmare themed map

If the universe is a simulation, what happens when the simulation ends or we die? Our consciousness has to exist outside of the simulation, right?

Yes, of course.

Here's a redpill for you:
>Quantum mechanics is merely a result of the simulation losing floating-point accuracy at that scale

Nick Bostrom and all the other singularity guys like Kurzweil are smart but they're all so far up their own asses it gets annoying.

Not if the simulation is stopped every once in a while, which you of course are not noticing because you are in the simulation, or in other words, a figure in the videogame doesn't notice the lag.

Maybe that's the purpose of the simulation, to teach you how to handle suffering or some shit. And you are going to be reborn until you figured that out. That's at least what that Buddha guy kept saying.

The whole universe could be pre-rendered, and only the Earth is the simulated part. We are not really interacting with the Universe yet, so we can't prove it's actually real.

How do you know what is possible or impossible if you're living by the rules of the simulation?

Reality is relative. If I found out tomorrow that everything is "fake", but I had no way to access "reaity" in any way, my life would not change in any way besides maybe going "huh, neat."
