Elon Musk: 'One In Billions' Chance We're Not Living In A Computer Simulation (vox.com)

An anonymous reader writes: At Recode's annual Code Conference, Elon Musk explained how we are almost certainly living in a more advanced civilization's video game. He said: "The strongest argument for us being in a simulation probably is the following. Forty years ago we had pong. Like, two rectangles and a dot. That was what games were. Now, 40 years later, we have photorealistic, 3D simulations with millions of people playing simultaneously, and it's getting better every year. Soon we'll have virtual reality, augmented reality. If you assume any rate of improvement at all, then the games will become indistinguishable from reality, even if that rate of advancement drops by a thousand from what it is now. Then you just say, okay, let's imagine it's 10,000 years in the future, which is nothing on the evolutionary scale. So given that we're clearly on a trajectory to have games that are indistinguishable from reality, and those games could be played on any set-top box or on a PC or whatever, and there would probably be billions of such computers or set-top boxes, it would seem to follow that the odds that we're in base reality is one in billions. Tell me what's wrong with that argument. Is there a flaw in that argument?" You can watch Elon Musk's full interview on YouTube.

      Personally, I don't think we are in a game.

So this is school, not a game. I guess we'll know if I'm right in about 50 years, on average.

      As for those that think this level of simulation is impossible, it isn't. There may be limits to hardware that prevent exponential increases from going on forever. But there are no such limitations for software. You can optimize the simulation by doing things like dropping information whenever you don't need it (quantum mechanics), and removing redundant calculations (as in, after a quadrillion people go through the same sim, it is unlikely they are actually coming up with anything original...)

      How can you say that SpaceX is not profitable at the moment? They have not had an investment round for several years now, except for the Google investment that seems to be aimed at something other that building rockets. SpaceX is also going to have well over a dozen launches at the current launch rate unless there is a major glitch that appears which would ground the launch fleet.

      This comment would have been appropriate in 2009 or earlier when SpaceX was still flying the Falcon 1 and still struggling to simply get into orbit with only announced plans for the Falcon 9 and some test hardware in the assembly line. That is no longer the case right now.

      If Elon Musk succeeds at sending a probe to Mars in 2018 like he already announced, it isn't just talking about Mars but rather actually going there. He also committed to sending at least one payload to Mars on every Hohmann Transfer Orbit opportunity between the Earth and Mars for as long as the company exists in the future (and mentioned in the above video). The question isn't just pontificating about what the future could be like, but rather holding actual hardware that will be on the surface of Mars in a definite time table.

      When companies talk about spaceflight, I always look at "bent metal" to see how serious they are about getting the job done. SpaceX certainly has plenty of bent metal to prove they are serious about going into space and a growing resume of completed missions in space.

      Jainism is a refuted doctrine with very few followers. (about 5 million worldwide) It was growing at the time of Siddhartha ("the Buddha") and indeed many Buddhist moral teachings are phrased specifically as comparisons with what Jain was teaching.

      The reason I say "refuted" is that one of the most important beliefs is a sort of strict compliance non-violence; if you step on a bug, and it dies, you have murdered a living being. It is the same as premeditated murder of a human. It was an interesting idea, but it does not survive the microscope; you can't eat vegetables without also eating lots of living animals.

      That is connected to the standard Buddhist concept of non-violence, which instead of being strict is based on intent. The formulation given is also a major moral debate with the Jainists during Siddhartha's life. The idea is that a monk who is sweeping the path and kills some ants that are on the path has not committed murder, because his intent is only to clean the path; he did not approach the path with the broom for the purpose of killing ants. And there is no way to sweep the path without some ants dying. A Jainist commits murder if his broom kills an ant, regardless of his intent, regardless of if he even saw the ant or had any way to avoid harming it.

      The Buddhist concept of vegetarianism is also rooted in intent; it is not allowed for a monk to eat meat that was killed or purchased for him, but he is allowed to eat leftovers that would otherwise go to waste. And the test is if he believes, thinks, or suspects that the food was prepared specifically for him or for his visit. If his presence didn't cause the animal to be killed, then he has no moral involvement in the killing of the animal. But if it was prepared with the intent of feeding him, or more specifically if he thinks that might be true, then he has a share of the moral harm of killing the animal.

      There are other examples; Jainism is a philosophy that was mostly superseded by Buddhism and Hinduism for real, physical reasons relating to how possible it is to follow it even if you're trying. That's why there are only 5 million followers, when there were probably more than that 2 thousand years ago.

Photosynthesis depends on quantum-tunneling as well. If the quantum nature of the universe is some sort of evidence that we're a simulation, then what exactly are we simulating if the "real world" outside of the simulation does not depend on the exact same quantum processes? Obviously the hypothetical "real world" MUST have different physics if our quantum physical laws are merely side-effects of the limitations of our simulation. So... How does fusion happen in the "real world?" What about photosynthesis? How about LEDs, solar cells, and various computer components that all rely on quantum effects?

      It's absurd to think any of those things would be possible without our very specific physics. The only possible explanation if we're in a simulation would be that the "real world" has completely different physics than ours. That makes me wonder why beings living in such a universe would bother to simulate a fantasy world where physics not only doesn't work the way it does in the "real world," but would also bother to create an entire universe populated by sentient beings just to see how such fake physics would play out.

The memory wipe wasn't 100% perfect, and some spurious data was left over. That could also be why you seem to forget your dreams really quickly after you wake up.

      As for those that think this level of simulation is impossible, it isn't.

      Without ANY bugs? Really? The only way this idea works is if you have a divine programmer who cannot make any mistakes who created the universe. This is more like scientology than science.

      If we are in a simulation, I would anticipate it to have about 3 lines of code:

      1. initialize multidimensional structure full of 0s with one huge number in one location

      2. Apply unified theory of everything to structure

      3. goto 2.

      How would we know the simulation was resumed from a backup after a system crash? If our consciousnesses were preserved in a state at time X before the crash and then the program resumed we wouldn't know.

      These are all completely consistent with the physical laws of the universe we live in. The simulation must be simulating all the matter and fields we can observe and so bug would be an inconsistency in the laws of physics. For example gravity not working at a certain time or for a certain object etc.

      This is incorrect. You only have to simulate one person[*].
      And any inconsistency can be corrected, and the emulation replayed from the fix point. No one in the surviving time line would notice.

    Mmm. I'm not sure I agree with the reasoning. You and I can run conway's game of Life on a computer, fast enough to update an entire screen in real time and see things evolve. GPU's are awesome.

    But if you and I are the analogues for the nodes in that Life simulation, we have no concept of how much time passes between each simulation step. For all we know, it could take aeons of what we would perceive to be our timebase for the simulation of every Tp (Planck Time). We would never know any different.

    The argument of resource is equally unconvincing - to the (strangely, intelligent :-) nodes in our hypothetical game of Life, the very idea of simulating a complex environment is outlandish, but to us it's a simple situation, taking up next to no resources. The expectation is that the next "level up" that would be running our reality as a simulation would be just as much of a difference (or more) to us, as we are to the game of Life. Ad infinitum, of course.

    s there a flaw in that argument?"

    There are lots of flaws in that argument. It's basically a version of the brain-in-a-jar argument. It is an argument possibly from a false premise. It has no physical evidence and (so far) no testable model to verify it. It's a mathematical and philosophical argument based on extrapolations and probabilities and axioms, not a (yet) physics argument based on empirical evidence.

    This is one of those times where somebody from physics tries to play in philosophy without knowing that this is ground that has been covered before.

  21. Allegory of the Cave by bigpat · · Score: 3, Insightful

    The idea that we are living inside a simulation is far from original from Musk.
    Perhaps the most prominent contemporary proponent of this idea is the philosopher Nick Bostrom.

    It's also peripherally related to the idea of a Boltzmann brain
    https://en.wikipedia.org/wiki/...

    Also there is Plato's "Allegory of the Cave" which describes prisoners in a cave viewing the shadows on the wall as their reality and similarly our own view of reality being perhaps like a "shadow" of a meta reality.
