what the hell does that mean "brains can be downloaded to a computer" ?
the computer will have a copy of my brain, and be able to think like i do?
i agree with the computing power being exponentially greater, but speeds of a computer don't bring about scientific functions of a computer.
if they can come out with something that can copy my brain, they can come out with it using my home computer or a supercomputer in 50 years. its a new technology, not directly correlated with processing speeds.
"IBM's BlueGene computer can already perform 70.72 trillion calculations a second and Pearson said the next computing goal was to replicate consciousness."
no, sorry, the next computing goal is to perform 70.73 trillion calculations a second.
if he's right, then they'll be Artificial Intelligence by 2020.
they also predicted we'd have flying cars by now.

I think that there are just some places that mankind was not meant to delve into. I think that there is too much of a risk of ****ing something up to even risk that procedure. We're on some shaky ground here, and we all know what nature does to its competition. But that's just me...

The crazy part too was them talking about the PS3 being 1% as powerful as the human brain! And the PS3 is 36 times more powerful than a PS2 and it has only been like 4-5 years since it last came out. So by 2050 I can definitely see that happening. I still think it's insane to even think about.

I would tend to agree with James here, and not just for the Bondian allusion in his name .Originally Posted by James007
The 90's was the decade of the brain, when neuroscience really lunged forward, but as far as I know their is still much to be discovered about the brain. Therefore, it seems premature to suggest that computers will be able to outperform the brain when we don't even have a sense of the full capacity of the brain. I think they were computer scientists, not neuroscientists, who were making those claims. Nonetheless, this is a dilemna we will certainly have to confront, probably in our lifetimes.

Brain beats all computers
By Roger Dobson
14 September 2003
Forecasters who predicted that computers are poised to become more powerful than the human brain have got it hopelessly wrong.
For the first time, researchers have calculated that the power of a single brain in terms of memory capacity and discovered that it is greater than all the computers ever made.
While even the biggest computer has a capacity of around 10,000,000,000,000 bytes (10 to the power of 12), the human brain has a colossal 10 followed by 8,432 noughts, say the scientists who made the calculations in the journal Brain and Mind.
The researchers, who point out that memory is the foundation of natural intelligence, say that the size of the memory capacity of human brains has been a mystery until now because no one has developed the right mathematical models for working it out.
The number of neurons, or nerve cells, in the brain is known - around 100 billion - and many analysts have used this for the basis of claims that computers will soon be superior to the brain.
But the researchers looked beyond that and used a series of algorithms to work out the total capacity, including the huge number of different neural connections.
Ironically, the discovery could be used to change the way that computers are designed. Instead of adding more bytes, they could mimic the human brain, with more emphasis on connections.
05-31-2005, 04:24 PM
This is actually irrelevant since we are talking about computation and not memory storage. Those are two totally different things. I totally agree that the brain has more storage and to tell you the truth I've read articles that the future of memory storage is the use of DNA since the body does it so well. It was something like 1 gram of DNA was equivalent to like 1,000,000 CD's or DVD's or something of storage which is insane.Originally Posted by TheCrownedOne
However, when it comes to computation, computers are definitely catching up. The brain can only do so much at once and with the emergence of smaller and smaller chip structures it wont be long before the brain is surpassed as far as overall computation is concerned. Not to mention when laser processing comes out!
05-31-2005, 04:31 PM
But the "power" of a computer is dependant upon its memory. A processor 1000 times more powerful than Gene is nothing without sufficient memory. Moreover, one of the greatest hindrances to the advancement of processing power is heat production. Smaller, faster chips create substantially more heat especially the more they are worked. I think the power of the brain is beyond what we will ever realize. Why do you think scientists still cannot understand how Kim Peek is able to compute any mathmatical problem almost instantly, recall with 98% efficiency every single thing he's ever read or heard, and count any amount of objects in less than a second? I believe everyone is able to do what Peek can do, but something about our conscious awareness and understanding of the world around us (something that doesn't exist wth autistic savants) prevents us from thinking the way they do.

With the coming of optical memory storage, supercomputers will have almost limitless memory storage using photons or even possibly DNA. Scientists know at one point they are going to have to use biological substances instead of manmade substances for later computers. I mean hell why not use something that has been perfected over the course of evolution!
05-31-2005, 04:41 PM
I've read that too about using biological structures for computer parts. But in a way that's just admitting defeat to the brain because instead of coming up with something entirely different they're just going to copy it. Either way, if we're still here in 2050 I'd better be seeing a flying car or teleportation or something "far out."

The flying car has been around for a few years, it just isn't practical and there isn't really any infrastructure or "gameplan" for it.Originally Posted by TheCrownedOne

Quoted for truth. The only way a computer will ever be self conscious is if a brain is actually connected to a computer. Like Beowulf said, it will be years before we even understand the human brain, and to say that the PS3 is 1% as powerfull as a human brain is reduculious imo. Whenever they say things like this they are always only looking at one aspect and not the whole thing.Originally Posted by James007
05-31-2005, 10:30 PM
SO WHAT if toshiba can make a 8gb chip the size of the pinky!?!?
the thing is, an 8gb chip or a 1 billion terrabyte chip are the same when compared to the brain, they are useless. they can't think, they can't learn on their own, and they are always useless without a human brain to function it.
A computer can perform much better at math, but that doesn't give it the ability to think.
and I doubt that AI will ever be created by humans, because from a computer programming viewpoint, in order to have the computer learn something new, you have to program it to be able to learn that thing. so the best to AI we will ever have is programming a computer every single thing possible.

You guys are overlooking so many things. Your not looking beyond present technology. You keep bringing up that the ps3 isnt 1% as powerful as far as computing power is concerned as the brain but the brain can be clocked as far as how fast it as (like clocking a computer using MHz, etc.) . It has nothing to do with memory because the brain evolved as a storage device. And programming is getting to the point now where computers CAN learn on their own.
You guys are also commenting based more on what you want to hear more so than what is more than loikely going to happen.
06-01-2005, 05:18 PM
That stupid playstation isnt even 1/1000 of a percent of the human brain.
Do you guysrealize how much processing power it takes to digitize a single 3D image.. forget comtemplating the image..
Our brains take sight, sound, touch, smell, emotion and coordinate all that to mean something then compare it to something similar so we can make sense of it.
The most complex computers in the world can only perform one of those functions and extrapolate the data.. and still have nothing to do with it.. it has to be interpreted by a human.
Think about looking at a toy red block of wood sitting on the ground.. true intelligence would look at the color, the shape, the size, its location, how it feels and extrapolate all that data.. compare it to previously seen items of a similar nature and conclude its a toy THEN think about why it was left there.. who left it.. what they were building.
Do you all even have a concept of how much computational power that would take.. the amount of storage to process all that data..?
in 50 years "maybe" they'll be close to something that could do the most basic attempt at the above.. but it will be a long time before we see anything resembling real intelligence.
06-01-2005, 05:46 PM
When people talk about AI it's always one isolated component of intelligence. Maybe computers will be able to match the brain for memory, or processing power and speed. The question is: so what? There are some people with massive brain damage whose brains can do these things, for instance they can catch a ball when it's thrown to them, but who otherwise won't move of their own volition. To create true AI you need to find out what makes people alive, what makes up consciousness. That's a result of a lot of things that computers may never be able to mimick or aquire. Emotions, the desire to live, to have kids, to keep going. The need for friendship and companions in life. Even if a computer were developed that perfectly mimicked every function of the human brain, how would you 'turn it on'? Another thing that's missed is our brains develop, they aren't born instantly. How and why they develop they way they do is as much a part of this question as anything else. The system is too complex to simply try and study one or even two or more aspects of it and get some machine to mimick that. Maybe one day they'll figure it out, but I doubt it'll be 2050.
06-01-2005, 09:14 PM
My personal opinion is that it's less of a hardware problem and more of an "understanding" problem.
We may never be able to create truly thinking machines, but machines that can mimic a wide variety of human actions/responses are probably not that far off. (Bots in games like Q3 and UT2004, and the programs designed for the Turing Test come to mind.)
Maybe I've watched too many sci-fi movies but the thought of truly sentient machines scares the bejeezus out of me.

First, LakemountD I admire your enthusiasm and interest in the article
If you look at where we are today in terms of computing power and technology, compared to 50 years ago the difference is amazing, especially on the consumer level. I am sure that the next 50 years hold some very exciting and revolutionary discoveries in the field of computing, surely ones that will change our everyday lives.
That being said, although it is fun to predict and dream about the future, a lot of these articles being passed around, especially the ones using the PS3 as a reference point, are just speculative horse ****. In fact, to even use the term supercomputer, and PS3 in the same sentence is ludicrious. This is not a knock against the PS3 as an entertainment platform, I have a PS2, Xbox, and PC, and I love them all in their own special way, but to compare them or their upcomming successors in power to a human brain is just crazy. Although computers can be refined to be highly efficent when designed for specific tasks, such as playing a game of chess, sorting a list of items, or performing mathematical operations very quickly, these are all things that are programmed into them by humans. We are a very very very far way off from computers being able to program themselves. In order for them to even be able to do that they would need to be given a state of awareness, which AGAIN would come from us. Our sense of conciousness, understanding, ability to learn, remember, experience, comes from nature or what have you, and theirs would come from us. Truth of the matter is we are still far off from understanding the mechanics of our own minds, and before we can give machines minds of equivalence we are going to have to understand our own fully. Maybe by the time that day rolls around we will have technology capable of doing something with it, but I do not see that day being 50 years from now.
06-01-2005, 11:46 PM
Well you guys have your own opinion but I think you over estimate peoples intelligence level lol. We as humans have trouble adding numbers let alone processing 15 high definition video streams at once (like the ps3 can do). For instance, in you head try to add up 34,528+32,943 and at the exact same time try and add up 352+2499. It is impossible to add them up a the same time, you would spend at least 5 seconds doing the first one alone. I am not standing up for gaming platforms here but merely trying to show that if a gaming platform, that is not even top of the line technology compared to places like Los Alamos, can have enough processing power to decode those kind of graphics and the damn thing is no bigger than a laptop then think 50 years from now. Lets not forget that computing power expands exponentially according to Moore's law, which has held up for decades now and should hold up for a decade or two more to come.Originally Posted by Milo Hobgoblin
Although I do believe that true artificial intelligence will be created in our lifetime, I don't believe they can be truly considered alive considering I am a Christian.

But still, you're dealing only with numbers. Humans could compute numbers like that if we were accustomed to it, but life does not require such computations so our brains aren't strong in the particular area. The thing is, much of our thinking is outside of numerical expression. Nearly everything we contemplate is such an abstract notion, very likely a complex mixture of reality and totally illogical imagination. No matter how many mathematical computations a computer can do, it is still only doing mathematical computations. Sure, I think supersmart computers with the capability to hear commands and respond in logical ways will be here soon. Computers that can probably write a perfect book, or compose a perfect symphony. But technical perfection has nothing to do with what is pleasing. AI will never have the gift of sponteneity. More important, it will never feel alone, or week, or useless, unless told to do so. Inner chaos is a big part of what we are as humans. Computers will at best only experience controlled chaos.Originally Posted by LakeMountD
