You would know and beable to figure out, even with life times,(reply>), @Stephen Yoho  No it’s not impossible to think that we might not be able to create consciousness simulated in some kind of digital environment. The simulation hypothesis is not a video game or some virtual reality that people in the  “real universe” are playing. It’s saying that somehow civilizations created conscious beings that exist in a simulation. <br>       We don’t even understand what consciousness is. Also there’s no way to EVER tell if artificial intelligence or a simulated brain is actually conscious. We could(and probably will) create some incredibly advanced android who could respond in all the appropriate ways to mimic a conscious being, but there is NEVER a way to tell if this being actually has the subjective awareness of experience that we call consciousness. <br><br>And how do you avoid the problem of an infinite regress of simulations. If you follow his logic then the simulations will create simulations  who in turn create simulations and you’ll have a never ending infinite regression of simulations. <br><br>And what is the motivation for the simulations. Are we being watched like some kind of entertainment for them. It’s such an anti-scientific hypothesis because ultimately what it saying is there’s some kind of external reality that may not have the same fundamental  laws and we will never be able to access it. <br>People think they can pick up on certain details that might lead us to think this is a simulation like a glitch or something. But what they’re missing is that if this truly is a simulation then we have no idea what the non simulated universe is like to be able to make a inference like that.,(reply>), @Stephen Yoho i dont believe in human existing simulators unless your a robot of some kind lol,(reply>), Figure out what? That we are in a simulation? Do you think your little character on Call of Duty thinks he’s in a simulation? Lol In Elon Musk’s words, if you just see where we went from something as simple as the game pong to where we are now and have virtual reality games, in a hundred years or even a thousand years, even if we don’t have a significant jump in technology and just continue to go at the pace we are now it is almost impossible that we will not have the technology to be able to create a simulation comparable to what we think real life is right now!
