discrete calculations of 1s and 0s in transistors are not capable of harboring sapient life with free will, mental processes may emulate the calculations of computers but they must involve random quantum fluctuations for the being to be truly sapient

transferring control over civilization to electronic beings would be like genociding ourselves and creating simulations of sapient beings to replace us, it would be a huge mistake

intredasting but not strictly proven, we know very little about such things

I think in generally we need to diversify the different forms of life that exist. However there is always a threat of one such form of life being vastly superior, expanding uncontrollably and eradicating all the others.

What about a cyborg with a human brain? Something that's mostly robot, but controlled by organics. It would be cool if they could transfer people to android type bodies like 'ghost in the shell' I'd totally sign on for that! Not sure though about getting a fully technolyzed body with only a human head though, (that wasn't explained in too great detail).

We are living in a simulation (56)

1 Name: te-kun : 2008-04-11 22:29 ID:BePokpVk

  1. It is possible that a civilization could create a computer simulation which contains individuals with artificial intelligence.
  2. Such a civilization would likely run many—say billions—of these simulations (just for fun; for research, etc.)
  3. A simulated individual inside the simulation wouldn’t necessarily know that it’s inside a simulation—it’s just going about its daily business in what it considers to be the "real world."

Then the ultimate question is—if one accepts that theses 1, 2, and 3 are at least possible, which of the following is more likely?

a. We are the one civilization which develops AI simulations and happens not to be in one itself? Or,
b. We are one of the many (billions) of simulations that has run? (Remember point iii.)

In greater detail, his argument attempts to prove the trichotomy, that:


1. intelligent races will never reach a level of technology where they can run simulations of reality so detailed they can be mistaken for reality (or this is impossible in principle); or

Life does have a reason beyond it's origins. It doesn't have to be religious, or anything like that. You can simply live in a way that either pleases yourself or that pleases those around you. We may be a simulation, but that doesn't mean that while we're in here we can't let ourselves fall into being human. We can still be what we were programmed to be.

An argument I heard once for this being a simulation, is when you would go about programming a simulation, in order to make finding the results you want easier, the programmers would set some rules/limits that can't be broken to reduce the randomness of the events that happen. (Speed of Light anyone?)

48 Name: Anonymous Scientist : 2013-09-23 12:39 ID:fm5N7XnS

I've also heard that absolute cold is a similar limit that reinforces this theory.

49 Name: Anonymous Scientist : 2014-02-11 09:59 ID:h9UxQzlD

Without a constant speed of light, there's no grounds for relativistic weirdness in physics. I'm not sure what exactly becomes more convenient with this added constraint -- maybe out of bounds problems?

Well, temperature is something of a bulk property. It involves groups of particles, rather than single bodies, atoms, or molecules.
0 K can't be found in this universe because even a single cold proton is subject to gravitational and EM influence from the surrounding entire universe. That universe will nudge the particle about, warming it.

Both of these apparent boundaries seem to cause, or at least emphasize, rather than inhibit, new phenomena.

50 Name: Anonymous Scientist : 2014-03-30 08:26 ID:sfxEy1Nu

It seems to me that any accurate, large scale universe simulation is impossible as a matter of principle. The amount of energy it would take to run, having to simulate every particle in the universe realistically and simultaneously for trillions of years, would be as much or nearly as much energy/matter as there is in the universe. Otherwise the creation of such a simulation would violate things like the law of the conservation of energy in thermodynamics. So that the universe exists at all means that there is no simulation being run, meaning that if any "ancestor" universe exists it also cannot simultaneously exist AND run "our" universe, but we exist so it can't exist, or at least we are not a simulation.

51 Name: Anonymous Scientist : 2014-04-24 12:16 ID:C6kUYNww

We're talking about another universe you doofus. It may have way more energy available than ours.

52 Name: Anonymous Scientist : 2014-08-04 21:29 ID:qg8wXBwD


Why would it necessarily need to be a large-scale simulation? If one wanted to study something specific (the evolution of societies) and one could run a realistic enough simulation of -that-, one presumably would only need to give the appearance of their being something more out there in the universe (esp. if one wanted the conditions to be similar to one's own universe in order to simulate something like one's own civilization).

Sure, and the one simulating that universe would have more energy available, and the one after that would have more energy, so on and so forth into an effectively infinite amount of energy. Doubtful and there's no reason to believe it's true or even probable, it's superfluous. The simulation of any expanding universe would take up almost the entirety of energy in the simulating universe anyway over the course of time, and we live in an expanding universe.

CP is non-progressive so it's not a primary cause of death, and if you've got it bad you can't even commit suicide.

Yelp Inc. (YELP) has successfully grown to dominate a niche on the internet, a cross between the yellow pages and social networking.

2013 was a major bull market but tech appears to have stalled somewhat. It is feasible there may still be growth for tech stocks like YELP, some basic research on YELP is a good place to start this thread, it shows some of the resources I use for looking up basic info on a company.,_Inc.

I use it to gain power in general, power gives you more options whatever your motivations. You might want to become biologically immortal, you might want to help alleviate suffering, but you can't do any of this without wealth or power.

Knowledge is useless if not wielded by the wise, and I am aware there is more to it than that. There is a kind of information economy, you need information about information to determine the chances of it being useful in the practical sense which presents an interesting dilemma, since now you also need information about information about information about information, there are some parallels with calculus, this sounds like borderline autism but I am not obsessed with this or anything, it is just an observation I have made, when it gets to this point I usually just rely on good old human common sense and approximations to make the best decision. For instance if I am looking up penny stocks and I come across a dodgy company dumping millions of shares on the market with red flags everywhere when I go to their site, I know there is no longer much point in me spending more time on this, I go to the next one. If I next find a biotech startup and there are no red flags I have to decide whether it is worth trying to understand the drug they are trying to develop myself, I have to try and determine how long it would take and the opportunity cost of spending time on it or researching more companies. Through these means I can figure out how to make reasonably effective use of my time, how to valuate companies, risk and returns and the opportunity cost of various options.
