I've never been entirely sure why this debate matters.

A simulation, at least as we'd understand it, would mean some kind of set variables and set rules. It would be entirely deterministic, but you have to run it to see what happens.

That kind of sounds like…physics?

You have some basic elements like atoms and energy plus some set rules like conservation of mass, laws of thermodynamics, and the rest. Sure, we don't know what's going to happen next, but it does seem entirely determined.

Maybe I'm misunderstanding physics or the simulation hypothesis here. It's always seemed to me that we talk about a simulation as if it would be different than what we have now.

Why would the simulation be entirely deterministic? The simulations humans run often are not, see e.g. Monte Carlo simulations [1]. Also, the laws of physics as we presently know them are not completely deterministic either [2].

Monte Carlo simulations' goal is to randomise the inputs, not the process. In this hypothetical simulation of life, it is the process that seems deterministic, and not the inputs.

For Monte Carlo simulations, we want to be sure that we're not imparting the biases we have on the model into the execution of the process itself.

As for quantum mechanics, it is only with out current understanding that we believe the process is non-deterministic. We'll see if that holds in a century.

Monte Carlo can also be used to estimate completely deterministic quantities - e.g. hyper volumes under high dimension curves where it’s too expensive to numerically integrate but you only need a few sig figs of accuracy.

Proving that the Universe is a simulation would be proving the existence of gods. Considering how much effort humans have dedicated to this question over the millennia, and the various consequences, and the continuing influence on the lives of the majority of people, I would say it matters.
Re:Are We Living in a Computer Simulation? Let’s Not Find Out by ako on Sunday August 11, 2019 @03:01AM (#20666785)
So what would it mean if there are gods of simulation? Most religions and gods purely exist as a way to implement law and order: define what is good and bad, and to manipulate people to behave accordingly (otherwise you will be punished in hell).

Would simulation gods really be interested in us following good and bad rules, or more interested to see what happens if people do as they want?

If this is a simulation, my assumption is that it is to test if any highly intelligent and successful species is destined to destroy itself...

Well why wouldn't they be consistent? Just as you would add another column to an existing database table and run a data migration so that the new column makes sense in the context of the old and no one is the wiser, so can our simulators adjust the simulation as well as our understanding of the laws of physics in a manner that we could not discern. That is, if they are indeed able to pause and change anything.
Re:Are We Living in a Computer Simulation? Let’s Not Find Out by lordnacho on Monday August 12, 2019 @05:28AM (#20673812)

i don't think that proving reality to be a simulation would necessitate the proof of any divine beings. all it would really prove is that we are within a simulation that was put into place by something capable of doing such. there is no reason to ascribe "divine" or "holy" traits to those potential creators. granted, i operate under the ideology that there is no distinction between "divinity" and mundane reality itself. i more or less believe that religions were created to establish a schism between those two ideals and to set the divine aside because most people just cannot handle the true power of the infinite potential that lies within their conscious awareness. arbitrary power structures put in place so humans can point to something else and say that that something else is separate from us and better than us, instead of seeing that that something else simply is us— or more appropriately, the sum of us altogether. the way I see it, even if you are just a single lonely gear within a machine, connected within countless others, in being part of the machine, you represent the machine as a whole itself just as much as you represent your perspective as an individual gear.

From our point of view, any omnipotent being is a god. Even a near-omnipotent simulated being would fit the definition.

This doesn't mean they have to be worshiped or the center of any religion, it would just mean omnipotent beings do exist.

Re:Are We Living in a Computer Simulation? Let’s Not Find Out by ozzmotik on Monday August 12, 2019 @06:55AM (#20674264)
i suppose that's a fair assessment to make, but for me personally that isn't how I define a God, as there are several deities within older mythologies and religions that weren't exactly omnipotent (and even mortal ones such as the ones in Norse mythology). to me, the only real quality that endows one with the aspect of Godhead is the abstract concept we refer to as "divinity", or rather some intrinsic separation of the creator from the created, as it were. now, certainly, if some higher order lab tech created the simulation, you could argue that they are indeed separate from it, and in having the power to create it, they do have the power to modify any aspect of it, but I still don't believe that imbues them with any sort of divinity. as far as I can see it, they could likely just be the same as us: a simulated being under the purview of an even higher order of complexity.

but ultimately the point for me is that I just don't believe in "gods". it's not that I don't believe that the archetypes and characters introduced by mythology could never possibly exist, it's more that I don't personally believe that there is any intrinsic difference between us and them other than just the order of complexity upon which our experience of life and reality is founded. i believe more that the idea of "God" is more akin to the sum total of all information within a given "system" (be that system a universe, multiverse/omniverse, or some even further abstract concept); not so much a demiurge or some active participant, but rather an emergent phenomena that manifests as a synthesis of all of lower orders of complexity beneath it. this does not imbue the Godhead concept with any sort of special or separate nature, in my opinion, and in fact if anything, implies that divinity in and of itself is more just a specific modality of consciousness detached from the ego and the perspective of I-ness

> Maybe it's circular.

Sure, if not directly circular then consider that our simulations today are used to explore choices/behavior before doing something, so it stands to reason that as each universe sim gets to some interesting data, the sim operators learn something, then change their behavior accordingly and tweak the sim and re-run, learning something new in turn, followed by more sim tweaks, ... etc.

We today learn new insights from AI and then change our behavior, pour $billions and dev time into designing better AI, etc...so there's definitely a symbiosis relationship.

And I expect that we will eventually want to design AI that designs better AI than we can ourselves, which will teach us how to design better AI-designing-AI...etc. :)

We could prove the existence of the simulation runners.

That does not suddenly mean theists were right. They would still be just as wrong as ever, making random assumptions without any evidence or scientific method at all.

Lets say we were able to find out that the simulation runner looked and acted exactly like Zeus; that still wouldn't make Zeus worshipers right, just incredibly incredibly lucky in one of their random guesses.

Idk about your proposal of what makes one person right and another not.

Someone can have a starting point of life with the genetics & environment conditions needed for all the events to happen for making the "right" theory.

Another person can have a starting point (different than the other person) and where all the events to prove with the scientific method of what is the "right" theory; matching the other person.

Realistically each person would be effected by forces from previous lives that made them come to the conclusion at the end.

It's more like the simulation authors can influence population of different places to have different religions, ideals and rules, to see which one would win. If you look at it, it could be some kind of optimization, you put different ideologies together and see how they interact (commerce, wars). This also allows avoiding cultural degeneracy, i.e. seeing some prosperous society turning into something horrible (e.g. sacrificing humans daily to make sun rise), that would be then killed off by a competing culture in an inevitable clash of cultures, leaving the stronger/more viable alive. I worry about globalization as a single unified culture because of human tendency to degenerate; having a cultural competition seems to be needed for humanity to progress.

But physics as we understand it, isn't entirely deterministic.

There seem to be a number of other potentially important differences between living in a simulation and some other kind of "baseline" reality. One of those might be that a simulation sits inside of some kind of outer reality. It could therefore potentially be effected by that outer reality.

Physics can be entirely deterministic. What we believe is quantum physics can be the result of local hidden variables. Even multiple universes that are interfering with one another. Also the possibility that what we cannot measure as a repeating pattern under fixed conditions, is in fact following a pattern but not within our lifetimes to measure. There are so many possibilities that can make something appear random but in fact is truly deterministic.

Re:Are We Living in a Computer Simulation? Let’s Not Find Out by cryptonector on Sunday August 11, 2019 @02:23PM (#20669593)
It's the same with Free Will. Whether the universe has only deterministic laws, or a mix of deterministic and non-deterministic laws, Free Will doesn't follow: one way everything is predestined, while the other you don't truly have control of your actions, so neither way do you have full control of your actions. We already understand this now, and yet we carry on and pretend we have Free Will -- we have no real, appealing alternative.

It would be the same with proving that we live in a simulation, or that there is a god or gods, except as others have pointed out, we'd probably seek sandbox escapes.

Also, not every proof of being a simulation would necessarily be that. Any proof that our universe is a 4D projection of another with different dimensions might not include a proof of the direction of projection -- ours might be the true reality, and the other a projection of ours.

The same thing has been said about many man-made electronic systems, and we know how that’s gone so far ;) So I think for 95% of people, nothing would change, but for the folks on the forefront of experimental / particle physics, quite a bit would change because we’d be looking for a whole new class of exploits/vulnerabilities/ways to affect change in the simulation.

At the very least, knowing that violations of the model might not mean the model is wrong, but that there are glitches in the simulation would have a big impact on the search and interpretation of such glitches.

No longer could you say, "Well, our model is wrong." Now you would have to say, "Well, our model might be wrong, but also this could be a flaw in implementation." And the latter may be more exploitable than the former; at least for awhile.

> If we were in a simulation the "glitches" would probably be something small and subtle, at sub-atomic level, not something that teleports you or gives you superpowers.

There's no guarantee of that at all. A bigger problem is that if we find a glitch, the simulators might just shut down the simulation, patch the glitch, roll back time a bit, and then restart it and we'd be none-the-wiser.
