what to do once you realize youre in a simulation
Do we live in a simulation? The trouble with this mind-angle hypothesis.
Paul M. Sutter is an astrophysicist at SUNY Stony Brook and the Flatiron Establish, host of " Ask a Spaceman " and " Infinite Radio ," and author of " How to Die in Space ." Sutter contributed this article to Space.com's Expert Voices: Op-Ed & Insights .
Is everything we know and feel, up to and including reality itself, a simulation created by some unseen and unknowable entity? This idea, known as the simulation hypothesis, was first posed (opens in new tab) past University of Oxford professor Nick Bostrom in 2003.
But does the simulation hypothesis offer a compelling argument, or is information technology just interesting food for idea? Permit's find out.

Permit's assume our computers will continue to grow ever more than powerful, efficient and capable. Let'south say that at some betoken in the deep, deep future (for this statement to work, information technology doesn't matter exactly when this happens), we build some ridiculous planet-sized computer — a computer and then powerful that information technology could simulate our entire universe, recreating all the physics, chemistry and biological science that nosotros experience in the natural world.
If we too presume that consciousness is consciousness, regardless of where information technology resides (in either an organic brain or a digital one), so any imitation entities within the calculator that gain consciousness volition feel a globe that is indistinguishable from ours.
You know, the Matrix.
One time our descendants build such a computer, they will inevitably create endless fake beings — but try to count how many creatures in video games have appeared and disappeared since we first adult the technology. Very quickly, the number of simulated conscious brains living in a computer will vastly outnumber the organic brains living in the real universe. If this ends up happening, we are left with three possibilities:
i. Our descendants (or other intelligent beings in the universe) will never be able to develop the technological ability to faithfully simulate the cosmos.
two. Our descendants (or other intelligent beings in the universe) volition develop the technology but cull not to simulate the cosmos.
three. The vast majority of all conscious entities, including you lot, are living in a simulation.
The simulation argument is the latest in a long tradition of philosophical thinking that questions the ultimate nature of the reality nosotros feel. Through the ages, philosophers have wondered if our reality is the construct of a malicious demon, or if we live inside of someone else'south dream. It's the ultimate course of skepticism and is useful to remind ourselves that in that location are limits to the empirical study of nature.
Equally philosophical arguments get, the simulation hypothesis is a good ane. But the hypothesis ends with a trilemma — three statements, ane of which must be true (if you have all the assumptions in the argument), but nosotros can't tell which one.
Y'all're allowed to throw your hands up and say you don't know which possibility is the nearly likely to exist correct. Yous're also allowed to argue for one choice over another. For example, you could say that computers will never be powerful enough to faithfully simulate the universe or that avant-garde civilizations will ever detect it morally reprehensible to simulate consciousness. Or you lot could say it's all inevitable and we do alive in somebody else'due south simulation of a universe.
No affair which option you choose, even so, you need to bring in extra arguments across the original simulation hypothesis. Or, you could question the assumptions that go into the statement itself.

Resetting the computer
Perhaps the biggest assumption in the simulation hypothesis is that simulated brains will quickly overwhelm the number of organic brains. Bold that at that place are no differences betwixt the experiences of false and organic consciousness (another large supposition), this is what allows yous to summate the odds that you live in a simulation. In the far future, for example, at that place could exist 99 billion faux witting beings for every 1 billion organic ones. That would mean there's a 99% gamble that yous are amid the simulated ones.
But in 2017, Brian Eggleston, an undergraduate systems analysis educatee at Stanford Academy, discovered a major flaw in Bostrom'south accounting (opens in new tab). The simulation argument relies on our descendants building superadvanced computers, because we are the only known species to build computers in the first place. One time our descendants build such computers, we'll know for sure that we're not among the imitation beings in those computers, because we tin bespeak to those computers and conclusively say we're not within them.
No matter how many simulated conscious entities our descendants make, whether 10 or 10 trillion, we can't use them to calculate the odds that we are in a simulation. In other words, their future ability to create simulated universes doesn't tell united states of america a unmarried matter almost whether nosotros are in a simulation. We tin't utilise the future numbers to calculate odds. And if nosotros tin't calculate the odds, we don't have a trilemma and thus tin't say anything more.
Instead, we can only await to our by — either humans living in some fourth dimension before us (in a nonsimulated, real universe) or some alien creatures who enjoy making simulated humans. While either of those realities is possible, we have absolutely no evidence that either is true, and we have no manner to calculate the number of false entities in being.
Practice nosotros live in a simulation? Ultimately, we don't know, and the simulation hypothesis doesn't provide a compelling argument that we might. And then yous can become back to enjoying your life.
