Science fiction stories are filled with visions of artificial intelligence (A.I.). Recent movies depicting robots with human-levels of artificial intelligence include I-Robot and A.I. Is this pure science fiction, or is it a genuine possibility in not-so-distant future? Peter Kassan answered this question in an article written for Skeptic magazine.
Kassan argued persuasively that the quest for A.I. has been, and will continue to be a dead-end street. Scientists have been unable to duplicate the intelligence of even the simplest of creatures, yet alone human beings. For example, although scientists have studied and mapped the neural patterns of the simple C. elegans worm, no one has been able to duplicate its base level of intelligence. C. elegans possesses a mere 300 neurons, compared to the human brain which contains 100 billion (100,000,000,000). Our cerebral cortex alone contains 30 billion neurons, and 1000 trillion synapses (1,000,000,000,000,000). That is 100 million (100,000,000) times the number of neurons, and 100 trillion (100,000,000,000,000) times the number of synapses of C. elegans. In light of such figures it becomes painfully obvious why developing human A.I. is nowhere on the horizon.
Advocates of A.I. retort that the task of replicating human intelligence is only a problem of time. They observe that computers double in capacity and speed every 18 months. Based on this they argue that given enough time, computers will be large enough and fast enough to create A.I. comparable to the human brain. But as Kassan points out, computational speed of computer processors is not the problem! The problem is the software. A.I. would only be as good as the program being run by the computer. While computers double in performance and capacity every 18 months, computer programs don’t. They increase in complexity at a far slower rate. Furthermore, experience has shown that the larger software programs get, the slower they become. Additionally, the larger the program the more room for error. A software program simulating the human brain would contain 20 trillion errors at a minimum. Kassan describes this “programming problem” by way of analogy:
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 25 million times larger than what’s probably the largest software product ever written, Microsoft Windows, said to be about 40 million lines of code. As a software project grows in size, the probability of failure increases. The probability of successfully completing a project 25 million times more complex than Windows is effectively zero.
What I found so interesting about the article was not so much what it had to say (although it was very interesting), but who was saying it. While I do not know Kassan’s precise beliefs about God, the fact that he wrote an article for Skeptic magazine tells me he is probably an atheist and advocate of Darwinian evolution. As such he does not believe the universe is the result of a designing intelligence, but rather blind, unintelligent, random chance processes. As part of the universe, human intelligence must have been produced by the same chance processes. Herein lies the absurdity of Kassan’s worldview.
Kassan recognizes the near-inconceivable complexity of human intelligence, and argues persuasively that intelligent designers (humans) will never be able to re-create it artificially. While I agree with Kassan this invites a question: How can time + chance create what time + intelligence cannot? If time + intelligence cannot produce anything similar to the complexity of human intelligence, surely time + chance would fail as well. Kassan would have us believe time + chance is better equipped to create complex intelligence than time + intelligence; that blind, unintelligent, random chance processes are better designers of intelligence than the most intelligent beings on the planet. That is a rational absurdity! How is it possible for chance to be better equipped to create an extremely complicated machine than human beings? How do natural processes create something that is 25,000,000 times more complex than the most complex program created by intelligent beings?
When Kassan boots up Microsoft Windows on his personal computer, does he ever think for a second that this extremely complex program consisting of 40 million lines of coded information was produced by unintelligent, random chance processes? Of course not! It is far too complex for that. How, then, can he look at something 25,000,000 times more complex than Windows and say it was created by time + chance? The disconnect in Kassan’s worldview is so glaring that I cannot understand how he can miss it. While atheists pride themselves on being rational, believing time + chance can produce complex intelligence whereas time + intelligence cannot is anything but rational.
This is just one more example demonstrating that atheists’ problem with Christianity is not one of the intellect, but one of the will. Christianity is not only intellectually plausible, but explanatorily superior to atheism. It is rejected, however, because people do not want to bend the knee. They want to be their own lord. Rationality takes a back seat to their perverted will.

This is some rather poor logic. Computer software like windows is not recursive, self-reproducing and adaptive. There are programs, easily written, that are all of those things. You can set an enviroment, seed the program to reproduce and edit itself randomly, weed out the failures based on the enviroment, and … ta da. Similar programs have proven clearly that biological processes which operate in similar situations work just as well. For example, a couple of researchers used a program to simulate the development of the mammalian eye from a slightly light sensitive single cell to the full optic system we have – they were suprised to find that in their most conservative estimates, the eye could develop in just a few hundred thousand years. Which is why we’ve seen the eye develop independently several times throughout history.
When you have an enviroment that rewards certain modifications and punishes others, individuals that reproduce and randomly mutate, optimal organs and even things like human intelligence are not just possible – but almost inevitable.
You should really read some actual evolutional biology texts instead of the bastardized re-readings of them that the ID hacks put out.

Oh, and one other thing:
It is rejected, however, because people do not want to bend the knee. They want to be their own lord. Rationality takes a back seat to their perverted will.
That’s just a bald-faced logical fallacy. You’re ascribing impure motives to those you agree with in a round-about ad hominem.
I can just say that you are a theist, not because your position is more rational, but because you ignore logic and rational argument because you find christian doctrine more comforting. It may or may not be true, but in the end, it’s just name calling.

The idea of intelligently designed software, in which intelligent agents set up the initial conditions and peramaters of the program, proving that X can evolve into Y by chance is a joke.
In regards to your comments on my “bending the knee” remark, I did not make that for a non-Christian audience. It is a theological assessment that I would not attempt to defend to a non-believer. I am specifically referring to the REASON why many non-theists reject some very good arguments for the existence of God. As far as the quality of their reasons for rejecting some of the theistic arguments, I absolutely stand by my comment that it has more to do with their will than rationality.
A lot of atheists have more blind faith than the average believer. Their rejection of God has less to do with the fact that there is not good evidence for God, and more to do with some emotiona/experiential problem with the idea of God’s existence. Their will is opposed to accepting it. They don’t want it to be true. I’m generalizing, but this is what I often see.
Of course, a person’s motives are irrelevant to what is true. An atheist may not want to accept theism becaus he doesn’t want anyone else to be a master over him, but it could still be the case that God exists. Teenagers don’t like the idea that they have masters over them (parents), but they still exist. Of course, it could be that Christians want to believe God exists as well, but it’s irrelevant to the question of whether He in fact does exist. What matters is not why someone thinks what they do, but whether what they think is true to reality. So I’m not guilty of any logical fallacy here, because I’m not arguing atheism is false because of the motives of atheists. I’m just observing what I see atheists do. It’s not an argument for theism.
If you read through my blog (and main website, http://www.onenesspentecostal.com), you will see that I do not engage in personal attacks and name-calling to make my point.
