and so on and we give the example of seammens for instance and so the seaman's digital twin uh is actually connected to that real world. It's not just a mere representation and and you do a simulation . So using tools like nvidia ombry words and so on uh you can actually simulate changes in this let's say you know a factory that you're building. So you have the AI factory, you actuallyhave a virtual representation of the factory built on top and then you have the real factory. So there are three layers but these are connected. So as you make uh changes you can see what effects it
And I can't convince you that we're not in the matrix. Why? We could be. Is this table real? Am I really here? Am I a simulation sitting inside some computer? Maybe there's a kid in 29th century Earth and they happen to allowyou and I to exist sitting at this table. And here's a big assumption.
scenario where we begin to question everything. You know, is this table real? Am I really here? Am I a simulation sitting inside some computer right now? Are we in the matrix right now? These are the kinds of things whichyou naturally can come to when you take a deeply skeptical attitude to the
I want to propose a contrast between simulation and emulation. Simulation is done with cause and effect, formalisms, schematics, that sort of thing, basically, arrows and pointers moving from nodeto node by my version of it.
Or as some of you will know, you might be a wholly computationally realized subject of experience in a Nick Bostrom world simulation , and so on.But you can't doubt that at least it seems to you that you're having the experience right now of seeing me and hearing me talk.
before you have to do them. Simulation technologies and flight simulation was first invented in the 1930's by the Air Force in order to train pilots in foul weather flying without actually having them go upin bad weather. The first simulator company, The Link Company, was an organ company not
You've got two nickel sized men free in the world. Think of the posibilities. The simulation came back, You can jump out of the freaking blender. Alright, okay. I'm glad we went through this, this exercise.
- post AGI would you choose solving the problem that some of the smartest people in human history contended with. The simulation , nature of reality, and what is the bounds of, you know, what can be modeled.
everything that goes near it gets sucked in. But simulation theory is not one of them. The theory which was um proposed
And so that was what started me down this whole rabbit hole of simulation theory, was by speculating how our technology would evolve to what I call the simulation point, the point at which our virtual reality is indistinguishable from physical reality. Awesome. So before we delve into all the fascinating specifics, I was wondering if you could summarize for us the thesis of your book.
So you think if we're living in a simulation it's more likely an RPG simulation than an NPC simulation , or maybe the technology that created the simulation is so far ahead of us that it could be either way? Yeah, I actually think it's a combination.
And if you have to make all series of different question, like how do you deal with that? The simulation argument is referenced in a recent video game, called "No Man's Sky" by Hello Games, which my co-author Dan actually worked on.
And this one's from Maven. A simulation . Solar winds. These are the solar winds.
But in fact, it's just failed to save either. The simulation that you did for the corridor experiment, the actual real world experiment, the simulation track the other robots
Syntax is not semantics. And simulation is not duplication. You can simulate-- you're going to have plenty of time for questions.
That's the idea of a horizon. a simulation embedded on a computer in some higher reality.
themselves would simulate parallax and move. But the complicated analog computing of these, but when it came to simulating the Apollo mission soon gave way to this: the very first digital simulation ; a program which could store 256 edges and polygons that was used by each Apollo astronaut to simulate over and over again the process of landing on the moon with the lunar lander.
There is always uncertainty. The new way of forecasting, the way that's going to dominate the century is probabilistic forecasting. And the way it works is, you don't do one computer simulation . You do 50, you do 100, you do 200, each slightly different, each reasonable differently. So you'll have a multitude of forecast and you can use those multitudes of forecasting to get an idea of probabilities. A gross example is, if half the simulation
These simulations that I've run say that things can get Much better in terms of GDP.
computer simulations ? Do we know what they look like?
Our simulations look so much like the real universe that there's gotta be something in the universe that is like what we simulate.
These simulations are games without the scoring.
These simulations cost 100,000 to a million CPU hours per galaxy.
These simulations cost 10 or 20 million CPU hours, and you get tens of thousands of galaxies.
computer simulations to calculate what kind of image to create in the sound field and create the same image. So what we're doing is light and sound. I think
shuttle simulations that students go through and groups like the Nature Conservancy just happens to be a charity that I particularly fond of that I also
The video is a simulation , but it's been validated by the experiments done at SLAC.
If we rerun the simulation , you'll notice the outcomes are always slightly different, but the winning species consistently have high replication and low death and mutation rates.
If we run our simulation enough times, sometimes the winning gene won’t be the one with the traits that maximize its own survival.
- With this simulation , Barabasi and Albert showed how hubs could emerge in virtually any complex network.
That person, if they were scaled down to 1% of their original size, they would jump 42cm high. The simple simulation shows a jump height of 42cm. So you would make it out.
here was a simulation that you could mess about with and the simulation seemed to have a personality. So you could push and see... And the world would
everything that goes near it gets sucked in. What about simulation theory?
present our current simulation is running, if you asked them to build a social
through the simulation to be more prepared for the job is not only a benefit for the airline but also a huge benefit for the employee.
But once we have more realistic NPCs that live in the metaverse that can actually talk to us, we're getting closer and closer to what I call the simulation point. And then finally, the last stage is that we can download our consciousness completely into silicon.
It was almost a point of no return. And I believe the simulation point is a kind of technological singularity. Once we reach that, once we can have experiences that are so immersive that we forget about the physical world and then we have intelligences that
And so if you were to try to build "Fortnite" or "World of Warcraft" back in the '80s, the computer scientists would say, well, we don't have enough processing power. Let's run a simulation and say, OK, what if I do that?
Like we had simulation TDs who got to direct their films.
We can connect the simulation to virtual worlds and get virtual behavior.
They are a simulation based on the reality, but we don't know what the gravitational wave universe looks like.
But because the simulation 's flawed, it will not work in the real world.
Within a simulation , it's all information that's being rendered.
This is an echelon simulation of road cyclists in an angle with a strong crosswind.
This is a simulation we've done for Team Ineos in preparation for the Tour de France.
Here is a simulation that we did on drafting and triathlon.
Lots of simulation Monte Carlo stuff gets used.
adapt as the simulation gives you feedback.
It's like a simulation , an experience.
So the simulation universe theory that Elon Musk talked about, I wonder how astrophysicist view it.
