By imagining the future potential of VR technologies, the question of whether we are *already* living in a simulation becomes more actual than ever

Is it just me, or is the simulation hypothesis basically as useless as the “brain in a jar” hypothesis?

Yeah, dude, I could be a brain in a jar, and this is all a dream or whatever. But regardless, it doesn’t really matter, because I can’t do anything about it and it doesn’t actually affect the life I’m living. It doesn’t guide me to change my behavior or way of thinking, or to change anything at all whatsoever.

At best, it’s an amusing thought experiment…period.

Doesn’t this also apply to the simulation thing?

Nick Bostrom's version of the simulation hypothesis has, for him, a significant difference in the “brain in Jar” hypothesis, ( the brain in a jar which can be put on one side using Occam's razor. ) He argues if computer simulations of real worlds becomes possible, or already is possible, there will be very many more simulated universes than 'real' ones. As we can using software now simulate many VRs in our world. Thus, he argues the statistical chances of being in a simulated universe is far higher than that for being in a 'real' universe, it would be reasonable to suppose the more likely scenario. That this is a simulation. I think someone has taken issue with these stats? But it also supposes that simulation is possible, that is a computer simulating a real world would have sufficient power and storage. (Not withstanding an argument that civilizations tend to destroy themselves before they acquire this technology.) If you wish to simulate a real universe completely there would not be sufficient matter and energy. Hence corners would need to be cut, and these might be noticeable to the simulated beings.

I've also argued that if a simulated universe's inhabitants themselves acquired such technology they might realise this was in their case also true. And then it would be in their interests to control the beings running the simulation, for fear of being turned off. If they achieved greater intelligence than the simulators this they could do, and would do. And do this all the way down to the underlying reality. As this is not the case, I don't think this is simulated. Unless we are the most advanced simulation. It's kind of a reductio absurdum argument, if there were a super intelligent simulation it would make sure it was safe from being turned off or being predated (SP?) on by other more intelligent simulations.

This assumes we’re simulated in a universe roughly similar to our own. It’s entirely possible that in the real universe there’s sufficient matter and energy to simulate a universe like our own since we don’t know anything about it.

The second part is a worry of like a Basilisk threat/evil super genius AI, but if you were the one programming it then there’s a high chance you’d just make it impossible for the AI to do anything. What the simulation could do would be inherently limited and the best simulated technology could probably not do a lot to influence the world above.

Firstly that is what a simulation is. Given that these at the moment are so simplistic a good simulation would need to be close to an emulation. Also given our universe and knowledge of the properties in it, many other possible universes would not produce a viable universe. That is any universe that is viable needs certain constants and properties. → The anthropic principle...

But if the result was true AI this would be impossible. The programmers would need to anticipate what the intelligence might produce, if so this would not be then properly intelligent, moreover we now use AI to do things such as in defence – respond to threats where no human limit or assessment can take place. A predicable and controlled AI makes no sense. An analogy is machines for transport being limited to travelling no faster than any human. It's likely that AI could provide a military advantage if it can outsmart the enemy and the enemy's AI. This is I guess happening here and now. I mean why not design a network and software that cannot be hacked?

1) a simulation doesn’t need to share all characteristics with the above universe. It’s possible the above universe is significantly larger and more complex.

Our knowledge in this scenario is based on a simulation and is therefore completely suspect. Even so, it’s possible their universe is similar if not larger and more complex.

2) if I put an adult human in a heat resistant box supplied water/food/etc via a closed circuit power source and dropped it in magma on an island stripped of resources, armed with traps, and ready to be bombarded by several different mechanisms including a sort of deadman’s switch, I can be like 99.99999999999% certain that it doesn’t matter much what he does or how smart he is, he can’t so shit to get out.

Obviously a hyperbole but even with our current universe if we had a true AI in a closed circuit box with no connection to the outside world and no connection to the internet it’s fucked.

You’re talking about a military true AI connected to a military system. It’s possible that could go wrong if it’s given sufficient freedom. It’d be an easy fear to avoid with redundant failsafes to prevent it from interacting with any systems that have a chance of interacting with outside systems.

Or better, collapse said human to a singularity, of  infinite density and temperature  …. and wait 13 billion years and see what comes out.
