AI Expert Lex Fridman Weighs in on Simulation Theory

the Joe Rogan experience I'm gonna talk to you about that too because you brought up boström what do you bastard I'm relies on I mean he was relying on theories in terms of like mathematical theories of probability to to say that he thinks it's more likely that we're in a simulation yes he has a the thing he's articulated I don't think he's come up with the idea of the simulation he just kind of really thought about it deeply he came up with a simulation argument which is these three categories that he described to you possible outcomes I think the first one is we destroy ourselves before we ever create a simulation the second one is that we would lose interest in creating a simulation at some point and the third one is we're living in the simulation yeah what do you where do you lean I think - I think there's going to the three paths that he highlighted it makes it sound like it's so clear that it's just three but I think there's gonna be a huge amount of possibilities of the kinds of simulation like to me I keep asking you know to ask Elon Musk he's about the simulation wait he said what's on the other side what's outside the simulation yeah I think I asked what would you ask an AGI system he said what's outside the simulation is the question he believes in it hey or at least he entertains it as a troll the Elon Musk embodies like the best of the Twitter internet troll I mean and a brilliant engineer and designer in one it's like yeah it's like a quantum state that you can't quite figure out like what what's the coupling because I don't know if he's trolling but I'm the same way I love asking people out the simulation even though I get a little bit of hate from the scientific community but it pushes you get hate from the scientific community about the simulation because it's it's ridiculous notion if you think of it's like literally that because it's not a testable thing Lord we don't know how to just like why are you talking about this why do you sit down with Elon Musk and talk about the simulation we when you're sitting with the world but in particular aspects of rockets or robotics like I'm an expert but I came glad you said that I'm not expert anything but I know but a few things about autonomous vehicles why don't you talk to him about that right why don't we talk about simulation well the thing is the simulation pushes you outside of the muck the messiness of everyday details of science and makes you ask big questions about like the nature of our reality hmm and I I like to think of it as like what how would we build a simulation like what would be a compelling enough virtual reality game that you want to stay there for all your your whole life that's a first step there that's useful to think about like what is our reality what what aspects of the are most interesting for us humans to be able to perceive with our limited perception cognitive abilities interpret and interact with and then a bigger question then is like how do you build a larger scale simulation that would be able to create that virtual reality game which i think is a possible future we're already creating virtual worlds for ourselves on Twitter and social networks and so on I really believe that virtuality will enter we will spend more and more of our lives in the next 50 a hundred years in virtual worlds and the simulation hypothesis assimilation discussion as part of that I think I think there's the question of what's outside simulation is really interesting that's the other way of because like what created us what started the whole thing it's the modern version of asking what that what is God what does God look like what you know it's it's asking what does the programmer look like I think that's a fascinating question but arguing that we're already living this situation I think you've got stuck on that little point mm-hmm I think it's not that there's a bit of a language barrier to this like there's a technical yeah I think Nate it's funny it's funny Nick is a legit philosopher so he's been fighting battles in the philosophy game like you've asked them does somebody disagree with him yeah on these hypotheses and there's a lot of philosophers disagree but including Sean Carroll on the philosophical level and a lot of the arguments are in philosophy and then I'm sort of technical and they're about language and about terms and so on but I think yeah it's very possible that we we live in a we live in a simulation I think one of the this constructs of so physics theoretical physics with many worlds interpretation of quantum mechanics as Shawn's talk to you about reveals some interesting sort of fundamental building blocks of our reality there's something I don't think people have talked to you about which is like the coolest thing to me the most amazing thing that nobody can explain yeah things called cellular automata and there's a guy mathematician named John Conway who came up in the 70s with a thing called game of life and cellular automata are these two dimensional or one-dimensional but game of life is two-dimensional grid where every single little cell is really dumb and it behaves based on the cells next to it and it it's born when there's a fuse when there's like a certain number like three cells alive next to it and it dies otherwise so it's like a simple rule for birth and death and all it knows it's it's nearby surrounding in its own life and if you take that system with a really dumb rule and expanded in size arbitrary complexity emerges you can have touring machines so you can simulate perfect computers with that system and it can grow and all these behaviors grow like if you watch if people Google like a game of life and you can watch this extremely dumb simple system just grow arbitrary complexities and what you start to realize that from such incredibly simple building blocks that don't know anything about the bigger world around them you can build our entire universe you can build the kind of complexity as we see it less so like we think that God is like designing every little aspect or whatever of our world or a simulation hypothesis the simulation is designed by hand like I'm gonna craft these things what you realize is all you can all you need to do is just set some initial conditions set some really basic rules and allow the system to grow as long as it can grow arbitrarily just crazy stuff amazing stuff can happen from like from simplicity complexity can emerge and that for like if you study this a little bit closer just like watch it people can watch that a game of life on YouTube and think about what it's showing like for 10 minutes it'll blow your mind the fact that from simplicity arbitrary complexity beauty can emerge is like incredible so for the simulation the creator of the simulation is probably some 13 year old nerd living in like in his mom's basement it's probably just set some rules in this video game and press play and then arbitrary complexity can emerge it can have a Joe Rogan it can have an Elon Musk all the technologies that we've developed and probably millions of other alien species that are living throughout our universe so the yeah that to me the cellular automata reveals that the simulation is much easier to create than we might think and but there's a lot of variability and the kinds of simulations will create like I think the simulation hypothesis things like you know there's like one but I think there's were going to be a lot of varieties there's that there's that there's a lot of possible different rule sets there's about a lot of different physical mediums in which these simulation could be created it can be a completely virtual world the role of consciousness whether you make most people conscious or not whether most of them are philosophical zombies they're just like non player characters and it's just you or you have or is your mind simulated like the role of suffering so consciousness brings with it this idea of of basically you know subjective experience of a subjective experience comes the idea of pain and fear and so on the thing again my Russian romanticization of it but I think fear of death is essential scarcity is essential for community for life you know and that that's a nice feature of this little simulation we got going on that there could be a lot of different alternatives I think that could be less individualistic less less consciousness can be present in different kinds of forms so I see there's a lot more options than those three that he highlights and we can destroy ourselves in a lot of interesting ways the entire civilizations from AI to nuclear weapons to biological to all kinds of weapons so it's almost like whether it's a simulation or not is almost irrelevant the complexity of the existence and all of the various pushes and pulls that keep everything together they're they're almost operating like some grand plan whether they like it or not whether whether or not a grand plan exists all these different things are happening and everything is moving in a very specific direction right it's moving towards further complexity like I was having a conversation with a friend of mine last night where we were talking about phones and we were like you know like when are they ever gonna look at a phone and say I think we're good we don't have to the camera works great signals great and call people you can text people let's just stop innovating right here and we're both laughing like it's never gonna happen but even though we admit like if you have an iPhone 11 or a pixel four is that we have yeah it works they work great but you don't really need anything better like in terms of the way our culture works you get so much done on these things you can bank on them is okay if I'm drinking all your waters by the way yeah we have a lot of water yeah please that's very polite of you the just the existence itself whether or not there's a design to it it seems to operate in a matter that would indicate there's a design the design doesn't have to be real doesn't have to be a simulation it doesn't have to be a grand plan but it moves in this the same way as if it's a grand plan it's weird it's hard to put into words but there's a different force and a momentum like the evolutionary process the fact that life was created the fact that there was a kind of progress and also like just like with the Native Americans the the fact that suffering seems to be a constant story that was weaving in mmm-hmm like we would constantly progress but we seems to be like creating the other and torturing and there seems to be constant suffering and war and so on through this growth process and that seems to be the death is a huge part of that and and conflict conflict even social conflict like we were talking about social justice warriors and and that type of thing I think they almost have to exist it's almost like the world creates a space for them and people find a way to fill that space yeah [Applause]

This is exactly what we are. A simulation set in motion by creating a set of parameters with certain values (matter, gravity, time, space). Created from a reality where infinite parameters can be created. Parameters that we can't comprehend because we can only imagine what can exist in our reality.
