The human brain is adaptive. Certain stimuli can create whole new ways to process information. The complexity of an adult brain doesn't come about because of the complexity of the brain itself, but because the relatively simple action of learning has built all sorts of new pathways.
This AI would have to have the capability to do this. Obviously this is a complex thing to do, but the brain DOES EXACTLY THIS, and it does it in a NATURALISTIC MANNER. This means that if given enough time, we can eventually create code able to mimic the ability to learn, and from there we're home free. If you agree that replicating the learning behavior of the brain is possible, then by extension mimicking it to the point where it can, say, pass a Turing test will take time, but will be possible.
I think its worth pointing out that I by no means think that the experiences of the AI would have to be coded in. They would have to be put in as data, or stimuli, just like how a human experiences things through stimuli.
I have to submit evidence that says that AI"s are now being developed with the capabillity of "learning". I could grant you as far as that... however, this learning abillity only goes as far as i have mentioned earlier in my first post, through the five senses. Learning through the use of it, only going back to recognizing and responding again. I see a little kitten, and the flesh-bearer say it's cute, then it'll respond the way it saw the flesh-bearer respond. However, let me grant you a situation, where different type of people reacts differently to an aspect, will the AI "brain" able to process, compute and choose the best way to respond? [this situation is where the AI is granted only capabillity to learn how to react emotionally, without any code about responding emotionally at all] There might be a possibilty if the creator install a somekind of "judgement system" , and then it reacts [again] according to the data, not the way we express our emotion.
This is going back again to my theory that all of AI's capabillities in expressing their own emotions are "coded in". If what you say is true, to replicate OUR way of learning, the AI would be able to learn to create their own emotion, may i bring you toward the theory of knowledge... how reason, language, sensory perception and EMOTION grant us the capabillity to learn... it's like after finding out the chicken came before the egg, now the egg came before it... According to this theory, emotion help us at making decision on how to respond at something. Let me get back to the kitten situation.. an AI who's programmed that all kittens is cute, would even say an ugly one who almost die with cut and burns everywhere cute.. not even feeling sorry for it..however we as human would act fast to rescue it or kill it...
What im trying to gain from this theory is that emotion let us evaluate morally, ethically and so on and so forth.. where as as i could see that an AI with only programming and datas and their technologies are designed to recognize and respond.. of course i could say that we human beings also do that , but we don't just stop there, thats what. We don't let ourselves be in a tight minded situation when we react, like the AI's who are well....., programmed to do it, and would not go against it.
The theory of mechanism won't work with us, in some extent there will be a limit where human being could replicate the way our brain works, unless the creators of the AI's give them some kind of conciousness, i couldn't see how it'll develop learning abillity through the ways of knowing and react emotionally as we did..
Bear in mind the learning system developed have gone as far as only through the five sensory of perception, and may go to the use of reasoning, and language, and didn't even brush a single speck on the emotion "capabillities" even if they provide evidence that i would personally call a false claim if it were to be called expressing "emotion". I mean let's be realistic here, how many months it'll take to even cover about basic people facial expression, and change of tone, and how the AI's would respond to it? Years. And it only covers the way of learning through the five sensory of perception... how many years it'll take to learn by using reasoning? or logic, or by using language and other external influences or "stimuli"? and how long does it takes to make the "brain" of the AI to be able to process it all, and come with it's own judgement as we are now? I've lost count.
@Ogrilla
The very idea is genious, it adapt the surface area to volume ratio from cells. I might say that it'll work, through the sensory of perception AI's may learn human behaviour, billions and billions and human behaviour. And as i quoted, that the AI's will be more capable in mimicking human emotion and behaviour than we could, but there are so many human behaviours out there affected by culture, religion, geographical position, surrounding, any internal and external aspects, and so many ways to express their emotions.
I don't want to challenge that statement further yet, and i think it's quite clear :). However, there's a few question i'd like to ask...
Does the AI specifically adapt a certain human behaviour and emotion patterns? If so, does the decision derived by programming or own judgement?
If the AI's , as you say, develop the abillity to recognize more.. doesn't that mean that the AI's again only recognizing and then responding and not considering other aspect as to respond to a particular manner?
