Scientists say that they are decades away from creating A.I.?

Question:They cannot create a robot brain that compares to the human brain. Attempts usually results in robots that lack common sense and have trouble recognizing everyday objects such as tables and chairs. Although computers are great with numbers, the simple task of navigating around furniture is seemingly impossible for the current A.I. technology.

Why do you think that scientists cannot duplicate the brain? Is it too complex or is it that we cannot properly define consciousness as we know it?

First of all you need to appreciate what it is that a human brain is good at. Estimates of the capability of a human brain in computer terms (links 1 and 2) generally suggest it is very poor at storing and retaining information. Something on the order of two bits per second and a hundred megabytes total for most people. What our brains EXCEL at, however, is pattern recognition - estimates suggest it would take about a hundred million megabytes of working memory executing about a hundred million instructions per second to simulate this.

This is why it has so far proven impossible to design a program that can recognize airplanes from the silouettes as trained (and many not-so-trained) humans can (in spite of millions of dollars thrown at it). It is also why it can be difficult to design robots that recognize obstacles, much less plan ways to move around them.

But these are not necessarily insurmountable obstacles. We're talking about computer capabilities that might be developed in the next decade or two.

As a matter of fact, I will suggest that I am very certain we will EVENTUALLY have some kind of simulation of a human brain. If in no other way than by simulation the transcription of a human genome (which we recently sequenced) into a human proteome (protein-folding programs are getting better every day) and so on through a normal lifespan of a completely simulated human being. Much of that processing would be superfluous to just the generation of a machine intelligence, but it has the benefit of us not even needing to have the slightest idea about how to produce consciousness or thought... all we need to know is physics and chemistry to a plausible degree of sophistication and have a ridiculously powerful computer (though a quantum computer might handle such work easily, perhaps).

It is almost certainly only a matter of time.

Because it took five billion years of complex organizational evolutionary trial and error on our planet to come up with our brain, which has "trillions" of neurons and synapse connections and combinations of connections, and "5 Billion Years of Evolution" is a damn difficult effort to duplicate in just a short time...

The brain is too complex, scientists can and will make functional robots but nothing that compares to the human brain. The worlds fastest single computer operates at .7 teraflops. The human brain operates at 2.5 teraflop. (A teraflop is every trillion thoughts processed a second)

With the advent of computer processors getting tinier, I dont think it will take decades.

I wonder what they will do with us then.

i am sure scientist can produce AI that is light years ahead of some of the people I work with. Boils down to what is your definition of AI?

AI? Refine your definition...

I tend to think you are referring to sentience... or perhaps sapience... a duplication of the human mind, the human soul in a robot. Is that sort of thing what you mean?

I dont believe AI is possible... and here is why...

I believe we are stuck in a chicken and the egg paradox when it comes to AI.

I dont believe that true AI can exist without the emotional impulses of an animal body/mind... which causes illogic and irrational behavior. It causes mistakes and a development of personality through trial, error, and ill memories of regret and pride in success. So, emotional instinct must precede AI, as a foundation for it and its development.

After all, what sort of AI is an AI if it has no emotion? Without emotion there is no desire, no goals, no sense of purpose, no nothing other than its raw programming to guide its "decisions"... it has no basis for decision making other than raw facts and it has no -real- awareness of self if its capable of being ordered to its "death" without question.

But, emotion cannot be programmed into a non-AI machine. An AI intelligence must pre-exist the emotion in order to experience and analyze it. Because emotional impulses without the mind to recognize them is only electrical impulses without meaning.

Emotion cannot exist in a machine without the intelligence to feel and react to it. And intelligence cannot exist without emotion to mold it. An unemotional AI is little more than an robot with the ability to adapt to its situation, but has no imperative or concern... and so is not alive. What is life without emotion? No matter how adaptive a robot may be, how would emotion be instilled into it?

Therefore, we are stuck with insufficient ability to create artificial life.

Then again, what is human life? Do we even exist as beings with souls? Or are we just programmed biological robots? This is a spiritual and metaphysical question.

To create artificial life would devalue and degrade the human experience... not because we are sharing existence, but because it negates the necessity of a soul.

The human brain is incredibly advanced. Everything our brain does is an equation. Even as i am typing these words right now, i am calculating the time it will take me to press one key, and then i must think of the next key to type, and then press it. It is an equation our brains can do in miliseconds...Even when walking, we are calculating the pase of our stride, the length of our steps, and then adding in the factor of distance, in order to come up with a solution of when to stop walking, or how long it will take us to get to our destination. The tricky part for duplicating the human brain is coming up with an equation for all the everyday things that we do in life. Calculating time and distance, and speed, is one of the more common equations that we use in our everyday lives..it is the scientists jobs to identify every one of these equations and program them into the robot's "brain" and that is why it is very hard to do. I dont know much about robots configuration because im only a freshman in highschool and i dont care much for math lol like any other 14 year old...but im pretty sure that that is why.

Image Recognition isn't that much of a problem with A.I.

A more interesting problem is sabotaged deductive reasoning with the paranoid pathological lying in false economics capitalism and false government republicanism.

i'm not sure where you are getting your information. big business and IEEE have been developing fuzzy systems for years.
A.I. is a term that went out with your desktop...
systems using fuzzy logic are used by big business to 'capture' the expertise of retiring employees.

you can divide any astronomical amount of time by decades.
