This paper argues that at least one of the following propositions is true: (1) the human species is very likely to go extinct before reaching a “posthuman” stage; (2) any posthuman civilization is extremely unlikely to run a significant number of simulations of their evolutionary history (or variations thereof); (3) we are almost certainly living in a computer simulation. It follows that the belief that there is a significant chance that we will one day become posthumans who run ancestor-simulations is false, unless we are currently living in a simulation. A number of other consequences of this result are also discussed.
VICE: When did you first surmise that our reality could be a computer simulation?
Rich Terrile: Unless you believe there’s something magical about consciousness—and I don’t, I believe it’s the product of a very sophisticated architecture within the human brain—then you have to assume that at some point it can be simulated by a computer, or in other words, replicated. There are two ways one might accomplish an artificial human brain in the future. One of them is to reverse-engineer it, but I think it would be far easier to evolve a circuit or architecture that could become conscious. Perhaps in the next ten to 30 years we’ll be able to incorporate artificial consciousness into our machines.
We’ll get there that fast?
Right now the fastest NASA supercomputers are cranking away at about double the speed of the human brain. If you make a simple calculation using Moore’s Law, you’ll find that these supercomputers, inside of a decade, will have the ability to compute an entire human lifetime of 80 years—including every thought ever conceived during that lifetime—in the span of a month.
That’s depressing.
Now brace yourself: In 30 years we expect that a PlayStation—they come out with a new PlayStation every six to eight years, so this would be a PlayStation 7—will be able to compute about 10,000 human lifetimes simultaneously in real time, or about a human lifetime in an hour.
There’s how many PlayStations worldwide? More than 100 million, certainly. So think of 100 million consoles, each one containing 10,000 humans. That means, by that time, conceptually, you could have more humans living in PlayStations than you have humans living on Earth today.
You seem really at peace with this concept. When I first heard about your theory I was incredibly bummed but, obviously, intrigued.
I find great inspiration in it, and I’ll tell you why: It tells me that we’re at the threshold of being able to create a universe—a simulation—and that we in turn could be living inside a simulation, which could be in turn yet another simulation. And our simulated beings could also create simulations. What I find intriguing is, if there is a creator, and there will be a creator in the future and it will be us, this also means if there’s a creator for our world, here, it’s also us. This means we are both God and servants of God, and that we made it all. What I find inspiring is that, even if we are in a simulation or many orders of magnitude down in levels of simulation, somewhere along the line something escaped the primordial ooze to become us and to result in simulations that made us. And that’s cool.

The physics is mind-bogglingly complex and operates on a vanishingly small scale. So even using the world’s most powerful supercomputers, physicists have only managed to simulate tiny corners of the cosmos just a few femtometers across. (A femtometer is 10^-15 metres.)
That may not sound like much but the significant point is that the simulation is essentially indistinguishable from the real thing (at least as far as we understand it).
It’s not hard to imagine that Moore’s Law-type progress will allow physicists to simulate significantly larger regions of space. A region just a few micrometres across could encapsulate the entire workings of a human cell.
Again, the behaviour of this human cell would be indistinguishable from the real thing.
Today, we get an answer of sorts from Silas Beane, at the University of Bonn in Germany, and a few pals. They say there is a way to see evidence that we are being simulated, at least in certain scenarios.
The question that Beane and co ask is whether the lattice spacing imposes any kind of limitation on the physical processes we see in the universe. They examine, in particular, high energy processes, which probe smaller regions of space as they get more energetic
What they find is interesting. They say that the lattice spacing imposes a fundamental limit on the energy that particles can have. That’s because nothing can exist that is smaller than the lattice itself.
So if our cosmos is merely a simulation, there ought to be a cut off in the spectrum of high energy particles.
It turns out there is exactly this kind of cut off in the energy of cosmic ray particles, a limit known as the Greisen–Zatsepin–Kuzmin or GZK cut off.

Simulation would imply cheat codes.
Simulation or not, I could personally care less. It doesn't affect the tangible experiential nature of it unless we have those cheat codes.
Thus, no cheat codes, no matter, meh.
