Computers seem to be so good at so many things. They are able to calculate with accuracy and efficiency that very few humans could ever hope to match. They foster communication and connection in a manner which even some of the most complex social structures find difficult to attain. This has set me wondering whether there will ever come a time when computers are able to outperform humans in that third type of knowledge, spiritual intelligence.
In their superb book SQ Danah Zohar and Ian Marshall suggest that there are three types of intelligence. Firstly, there is IQ (Intellectual Quotient). This is the kind of intelligence that has to do with logic and reason. It applies certain rules in a very linear way to come to particular conclusions. In fact they suggest that this kind of intelligence operates within the human brain through a series of neural connections (neurons are the cells in the brain that fire the electric charges, or currents, that make the brain work) that are connected in a linear fashion. People who posses a high degree of this kind of intelligence can do calculations quickly, the operate well with rules, and are able to make fairly concrete, black and white, decisions. Of course computers can do this very well. They operate according to preset (or preprogrammed) rules e.g. if this happens then do that, if that happens then do this, if neither happens then do this or that (this process has become known as the Turing process, after it's designer Alan Turing). Because of the fact that this kind of intelligence works well with rules it did not take too long for computers to be programmed that could do things, which required an ability to operate within the constraints of certain rules, very well. For example the chess playing super-computer developed by IBM, Big Blue, which beat Gary Kasparov, the world champion chess master at Chess. Give a computer enough accurate programming and it will be able to adequately figure out what response makes the most sense. Add to that the processing power to perform these calculations with great speed and you have a machine that will outperform a human, within the ambit of it's programming, every time! However, change just one variable and the computer will be stumped. You see it can only operate within the limited confines of the program that has been fed into it.
The second kind of knowledge that Marshall and Zohar identify is EQ (Emotional Quotient). Of course, anybody who has read recent works in corporate culture and personal development should be familiar with this kind of the knowledge. This is a kind of knowledge that allows one flexibility to make creative and diverse choices within the confines of certain preset rules and conditions. Whereas linear, IQ, only allows one to make the choices of the program, EQ allows one to make choices within the scope of the program. So, if this isn't so, and that isn't so, it doesn't mean that I crash and stop working. Rather it means that I find another answer that works in order to solve the problem. This kind of knowledge is not linear, it is parallel. Within the brain it is suggested that humans have the capacity for this kind of knowledge because of extremely complex parallel neural connections. For example, I am learning to ride a bicycle and fall off. A logical thought process would say "you cannot ride a bicycle so you should not climb on one, since because you cannot ride, you will fall each time you climb on the bicycle". However, a complex, or parallel, thought would ask "are there any other instances that I can draw on, from other experiences that I have had, where I have learned how to do something that I could not do before? Yes there are, here is how I learnt these skills and abilities, so apply something similar from another context to this context [e.g. trial and error, perseverance, drawing on the knowledge and skill of others etc.] and I will learn how to do the thing that I cannot do know." Thus, even though it is logical and reasonable that I may fall off the bike again, because I cannot ride, my mind tells me that through processes that I already have some experience of I can learn how to ride. So I climb on the bike again. Computers are able to do this task well. They have two things in their favor. Firstly, they are able to store, or remember, things well. If information is stored it remains usable as long as it is made available to use, and of course as long as nothing goes wrong with the machine and wipes out all the data (a.k.a use a Mac, not Windows!) Neural networks and Artificially Intelligent (AI) machines that are programmed with the ability to alter their own code, or programming, in response to certain circumstances, are examples of this. For example, some companies use AI machines such as those mentioned previously to manage trades on the stock market. A machine may be programmed to automatically sell all stocks, or buy on more stock, if the stock level reaches a certain level. However, the machine also stores 'experiences' of the outcomes of previous trades. For example, the machine may store that three out of four times when the stock price suddenly dropped below a level when it had been programmed to sell off all stocks, it suddenly rebounded to a much higher level than it held before the fall. Thus, because of this 'memory', the machine alters it's programming to say something along the lines of "don't immediately sell when the stock reaches this level, first wait a day to see whether it rebounds, if it does not then sell, if it does start to rebound then buy". You can see that it is issuing itself and instruction which may be contrary to the initial instruction that the human programmer has given. But, at the end of the day the computer's new, or changed, instruction makes more fiscal sense. Where as a human trader may panic or grow impatient and make the wrong decision, an AI machine should become more and more accurate in it's decisions to sell or buy, the more experience and data it has to store. Again, add to this process increased speed and you have a very accurate, highly efficient, machine that could outstrip a human being in EQ.
The third kind of knowledge that Zohar and Marshall speak about is an integrative knowledge, which they call SQ (Spiritual Quotient). This is a knowledge that works not only with the rules (like IQ does), and not only within the rules (like EQ does), it works the rules themselves! Let's use another hypothetical, and very simplistic, example. A person lives in an oppressive society. If such a person only had IQ, they would either have to obey, or not obey the rules of the country. If the person had EQ as well, they would have to try and find ways of living within the rules (finding exceptions and flaws in the rules which to exploit). However, a person with high SQ would seek to live outside of the rules, maybe even creating a new set of rules. IQ asks, "How can I do it?" EQ asks, "What can I do with it?" SQ asks, "Is this what I want?"
Now clearly, this kind of 'transcendent' knowledge is not yet a capability of the computers that I use (although, I must confess that my MAC does seem to defy many rules!) However, the question that one needs to ask is why is it not possible, and just because it is not possible today, does it mean that it is impossible? Think about it, just 150 years ago it was not possible to phone another person, to fly, to drive a car, and a myriad of other things which are commonplace today.
One of the strongest set of arguments that are given for why this kind of intelligence will not be possible for machines are arguments which are based upon variations of the understanding of human consciousness. Many argue that machines will not be able to do this kind of thinking since they are not conscious. They are not creative, they are created. Many argue that the reason why we can apply SQ within our lives is because we are conscious beings, we can think, but more importantly we can think about ourselves. In other words, I can ask myself, "how do I feel about this, can I do anything about it, do I have to live this way..." More importantly I have something which is known as 'metacogition', the ability to think about my thoughts. A computer can only 'think' this, or 'think' that. It may even be able to alter it's 'thoughts' in some way (as mentioned above). However it cannot think whether the thoughts themselves are valid or not valid.
This is where the theorists fall into two camps. In his book God and the mindmachine John Puddefoot speaks of the monists and the dualists. Let's first talk about the dualists. These are people who say that mind and matter are two different and distinct things. Like the philosopher, Descartes, they say that mind is something separate and distinct from the physical works (res cogitans versus res extensia). Plato, of course, was one of the earliest recorded thinkers along this line. He believed that people were souls that were trapped in physical bodies. Within the Christian tradition we have many such neo-Platonic ideas (particularly those of the Gnostics). I have also noticed that forms of neo-Gnosticism are prevalent in many modern Charismatic Churches that emphasis the importance of the spirit over, and against, 'the flesh' (which is regarded as weak and sinfull). Anyway, the dualist argument holds that machines, which are matter, could never become truly conscious since they are a completely different 'stuff' to mind. They are physical and not spiritual.
The other camp are known as the monists. They are people who believe that everything is one and the same 'stuff' (see some of the papers that I have written on this website at http://www.spirituality.org.za which refers to such thinkers as the Quantum Physicist, David Bohm, and the monk Dom Bede Griffiths). There is a fare amount of current scientific theory that suggests that mind and matter come from the same common spiritual source. Of course as Christians we should hold to such a view if we take texts such as Ephesians 1:10 and Collosians 1:16-17 seriously. In short, the proponents of this view, whether Christian or from other faith traditions (particularly faith traditions that are not dualistic - such as Hinduism and Buddhism) hold to the notion that since all reality is of the same 'stuff' there is no reason why consciousness is not possible for something that is material. After all, we as human beings are matter and we are conscious. Thus, some theorists have applied variations of this view to suggest that machines (whether electronic, mechanical or biological) have the same capacity for consciousness, and thus transcendent or spiritual existence, as we do. Sure, this is a very strong view of Artificial Intelligence, it borders on manic optimism, but it is logical if one agrees with the underlying principles and thought processes.
So, it could be possible that machines could one day be better than human beings in all three spheres of intelligence, IQ, EQ and most importantly SQ. Popular films such 'The Matrix', 'Dark City' and of course the Stanley Kubrick classic '2001 a space odyssey' have all speculated to the outcome of such an eventuality. If evolution continues to operate, even at the level of consciousness, then it could be possible that humanity would become the inferior species. Thus, at worst we could face extinction, or at best be harnessed (ala The Matrix and Dark City) by machines for some menial task to sustain their life.
There is of course a far more optimistic approach to this possibility. This approach is based, in large, upon a variation of Pierre Teilhard de Chardin's notion of evolutionary cosmology (I have written something on that which you can find on my website at http://www.spirituality.org.za). de Chardin suggested that the whole of the cosmos is in a process of complexification, this evolutionary move can be traced from the dawn of time right into the future. In essence he postulated that the cosmos is evolving from the less complex, gross or material levels of reality (biogenesis) to the more complex and subtle spiritual levels of reality (noogenesis) to a point of ultimate consciousness which he called the Christ Omega or Christ consciousness.
Within such a model it is possible to assume that any move in complexification is a positive evolutionary move. Thus, any increase in consciousness is of benefit to the cosmos as a whole. Of course this view is non dualist, in that it supposes that everything (persons and the rest of creation) are all of one and the same stuff. Hence, it may be plausible, if one supports a notion such as this, to suggest that even if humanity does become extinct, or the lesser species in creation, this may be part of the evolutionary plan of the cosmos as it moves to a higher plane of consciousness.
I'm not so sure about all this. However, the one thing that we cannot deny is that the boundary between technology and human persons is quickly diminishing. Not only are we becoming more dependent upon technology for our very survival (and here I am thinking both of life saving technologies such a biomedical, mechanical lifesaving devices such as pacemakers etc. and simple technologies like computer that control currencies, electricity, and other day to day functions).
The one other question that is prominent in my thoughts is the question of when the crossover takes place between machine and person. The movie 'Bicentennial man' clearly illustrates the difficulty of judging this from the machine side. It asks the question, because a machine looks like, behaves like and has emotions like a human person does that make it human? The question is also asked very pointedly by Ray Kruzweil in his book The Age of spiritual machines, when he asks how far must a human person go before he or she is classified as a machine. For example, a person who has a Cochlear implant to assist them to hear would be regarded as human. A person with artificial limbs would be regarded as human, even a person with an artificial heart and vital organs is regarded as human. However, if we were able to take this technology to its extreme (which of course is not yet possible, but could at some time be a possibility) and do something along the lines of what some theorists suggest could become possible, i.e. downloading our brain and all it's thoughts, ideas, memories, feelings etc. into a computer, would that mean that the computer becomes human? Or does it mean that even though 'I' may still be the conscious element of the machine, because I am not biological, or largely so, that I am no longer human? What then if one uses a computer that is biologically based, using enzymes to process the code of 1' and 0's, rather than a silicon based machine? Does this make a difference?
These are some of the thoughts that occupy my mind in the wee small hours of the morning. I suppose I won't mind too much, as long as I don't become a Windows box!! ;-)
