The Skeptics Society Skeptic magazine. For decades now computer scientists and futurists have been telling us that computers will achieve human level artificial intelligence soon. That day appears to be off in the distant future. Why In this penetrating skeptical critique of AI, computer scientist Peter Kassan reviews the numerous reasons why this problem is harder than anyone anticipated.

Actually, a Web search for computational neuroscience finds over a hundred thousand webpages and several major research centers. At least two journals are devoted to the subject. Over 6,0. 00 papers are available online. Amazon lists more than 5. A Web search for human brain project finds more than eighteen thousand matches. Many researchers think of modeling the human brain or creating a virtual brain a feasible project, even if a grand challenge. In other words, the idea isnt a new one.

Create a machine with artificial senses and then allow it to learn, build a model of its world, see analogies, make predictions, solve problems, and give us their solutions. This sounds eerily similar to what Alan Turing. He, too, proposed to create an artificial man equipped with senses and an artificial brain that could roam the countryside, like Frankensteins monster, and learn whatever it needed to survive. The fact is, we have no unifying theory of neuroscience. We dont know what to build, much less how to build it. Program Care Da Click Automat'>Program Care Da Click Automat.

Thirty years ago, the estimated number of neurons was between three and ten billion. Nowadays, the estimate is 1. Thirty years ago it was assumed that the brains glial cells, which outnumber neurons by nine times, were purely structural and had no other function.

Even the most ardent artificial intelligence A. I. advocates admit that, so far at least, the quest for human level intelligence has been a total failure. Despite its checkered history, however, Hawkins concludes A. I. will happen Yes, we can build intelligent machines. A Brief History of A. I. Duplicating or mimicking human level intelligence is an old notion perhaps as old as humanity itself. In the 1. 9th century, as Charles Babbage conceived of ways to mechanize calculation, people started thinking it was possible or arguing that it wasnt. Toward the middle of the 2. Claude Shannon,1. Norbert Wiener,1. John von Neumann,1. Alan Turing, and others laid the foundations of the theory of computing, the necessary tool seemed available. In 1. 95. 5, a research project on artificial intelligence was proposed a conference the following summer is considered the official inauguration of the field. The proposal. 20 is fascinating for its assertions, assumptions, hubris, and navet, all of which have characterized the field of A. I. ever since. The authors proposed that ten people could make significant progress in the field in two months. That ten person, two month project is still going strong 5. And its involved the efforts of more like tens of thousands of people. A. I. has splintered into three largely independent and mutually contradictory areas connectionism, computationalism, and robotics, each of which has its own subdivisions and contradictions. Much of the activity in each of the areas has little to do with the original goals of mechanizing or computerizing human level intelligence. However, in pursuit of that original goal, each of the three has its own set of problems, in addition to the many that they share. Connectionism. Connectionism is the modern version of a philosophy of mind known as associationism. Connectionism has applications to psychology and cognitive science, as well as underlying the schools of A. I. 2. 2 that include both artificial neural networks. Download Software Icare Data Recovery 4.1 With Key 2011 more. The latest estimates are that the human brain contains about 3. The 3. 0 billion neurons of the cerebral cortex contain about a thousand trillion synapses connections between neurons. Without a detailed model of how synapses work on a neurochemical level, theres no hope of modeling how the brain works. Unlike the idealized and simplified connections in so called artificial neural networks, those synapses are extremely variable in nature they can have different cycle times, they can use different neurotransmitters, and so on. How much data must be gathered about each synapse Somewhere between kilobytes tens of thousands of numbers and megabytes millions of numbers. And since the cycle time of synapses can be more than a thousand cycles per second, we may have to process those numbers a thousand times each second. Have we succeeded in modeling the brain of any animal, no matter how simple The nervous system of a nematode worm known as C. Caenorhabditis elegans has been studied extensively for about 4. Several websites. Sct Live Load Software On Ipad'>Sct Live Load Software On Ipad. Although C. elegans is a very simple organism, it may be the most complicated creature to have its nervous system fully mapped. C. elegans has just over three hundred neurons, and theyve been studied exhaustively. But mapping is not the same as modeling. No one has created a computer model of this nervous system and the number of neurons in the human cortex alone is 1. C. elegans has about seven thousand synapses. The number of synapses in the human cortex alone is over 1. The proposals to achieve human level artificial intelligence by modeling the human brain fail to acknowledge the lack of any realistic computer model of a synapse, the lack of any realistic model of a neuron, the lack of any model of how glial cells interact with neurons, and the literally astronomical scale of what is to be simulated. The typical artificial neural network consists of no more than 6. This, despite a 1. Even if every neuron in each layer of a three layer artificial neural net with 6. Furthermore, artificial neurons resemble generalized Boolean logic gates more than actual neurons. Each neuron can be described by a single number its threshold. Each synapse can be described by a single number the strength of the connection rather than the estimated minimum of ten thousand numbers required for a real synapse. Thus, the human cortex is at least 6. It is impossible to say how many lines of code the model of the brain would require conceivably, the program itself might be relatively simple, with all the complexity in the data for each neuron and each synapse. But the distinction between the program and the data is unimportant. If each synapse were handled by the equivalent of only a single line of code, the program to simulate the cerebral cortex would be roughly 2. Microsoft Windows, said to be about 4. As a software project grows in size, the probability of failure increases. The probability of successfully completing a project 2. Windows is effectively zero.
