Will computers and robots ever become self-aware?

Lets take a closer look at a puzzle
Lets take a closer look at a puzzle

There is a very famous thought experiment from UC Berkeley philosopher John Searle that all Christian apologists should know about. And now everyone who reads the Wall Street Journal knows about it, because of this article.

In that article, Searle is writing about the IBM computer that was programmed to play Jeopardy. Can a robot who wins on Jeopardy be “human”? Searle says no. And his famous Chinese room example (discussed in the article) explains why.

Excerpt:

Imagine that a person—me, for example—knows no Chinese and is locked in a room with boxes full of Chinese symbols and an instruction book written in English for manipulating the symbols. Unknown to me, the boxes are called “the database” and the instruction book is called “the program.” I am called “the computer.”

People outside the room pass in bunches of Chinese symbols that, unknown to me, are questions. I look up in the instruction book what I am supposed to do and I give back answers in Chinese symbols.

Suppose I get so good at shuffling the symbols and passing out the answers that my answers are indistinguishable from a native Chinese speaker’s. I give every indication of understanding the language despite the fact that I actually don’t understand a word of Chinese.

And if I do not, neither does any digital computer, because no computer, qua computer, has anything I do not have. It has stocks of symbols, rules for manipulating symbols, a system that allows it to rapidly transition from zeros to ones, and the ability to process inputs and outputs. That is it. There is nothing else.

Here is a link to the full article by John Searle on the Chinese room illustration.

By the way, Searle is a naturalist – not a theist, not a Christian. Now, let’s hear from a Christian scholar who can make more sense of this for us.

Here’s a related article on “strong AI” by Christian philosopher Jay Richards.

Excerpt:

Popular discussions of AI often suggest that if you keep increasing weak AI, at some point, you’ll get strong AI. That is, if you get enough computation, you’ll eventually get consciousness.

The reasoning goes something like this: There will be a moment at which a computer will be indistinguishable from a human intelligent agent in a blind test. At that point, we will have intelligent, conscious machines.

This does not follow. A computer may pass the Turing test, but that doesn’t mean that it will actually be a self-conscious, free agent.

The point seems obvious, but we can easily be beguiled by the way we speak of computers: We talk about computers learning, making mistakes, becoming more intelligent, and so forth. We need to remember that we are speaking metaphorically.

We can also be led astray by unexamined metaphysical assumptions. If we’re just computers made of meat, and we happened to become conscious at some point, what’s to stop computers from doing the same? That makes sense if you accept the premise—as many AI researchers do. If you don’t accept the premise, though, you don’t have to accept the conclusion.

In fact, there’s no good reason to assume that consciousness and agency emerge by accident at some threshold of speed and computational power in computers. We know by introspection that we are conscious, free beings—though we really don’t know how this works. So we naturally attribute consciousness to other humans. We also know generally what’s going on inside a computer, since we build them, and it has nothing to do with consciousness. It’s quite likely that consciousness is qualitatively different from the type of computation that we have developed in computers (as the “Chinese Room” argument, by philosopher John Searle, seems to show). Remember that, and you’ll suffer less anxiety as computers become more powerful.

Even if computer technology provides accelerating returns for the foreseeable future, it doesn’t follow that we’ll be replacing ourselves anytime soon. AI enthusiasts often make highly simplistic assumptions about human nature and biology. Rather than marveling at the ways in which computation illuminates our understanding of the microscopic biological world, many treat biological systems as nothing but clunky, soon-to-be-obsolete conglomerations of hardware and software. Fanciful speculations about uploading ourselves onto the Internet and transcending our biology rest on these simplistic assumptions. This is a common philosophical blind spot in the AI community, but it’s not a danger of AI research itself, which primarily involves programming and computers.

AI researchers often mix topics from different disciplines—biology, physics, computer science, robotics—and this causes critics to do the same. For instance, many critics worry that AI research leads inevitably to tampering with human nature. But different types of research raise different concerns. There are serious ethical questions when we’re dealing with human cloning and research that destroys human embryos. But AI research in itself does not raise these concerns. It normally involves computers, machines, and programming. While all technology raises ethical issues, we should be less worried about AI research—which has many benign applications—than research that treats human life as a means rather than an end.

When I am playing a game on the computer, I know exactly why what I am doing is fun – I am conscious of it. But the computer has no idea what I am doing. It is just matter in motion, acting on it’s programming and the inputs I supply to it. And that’s all computers will ever do. Trust me, this is my field. I have the BS and MS in computer science, and I have studied this area. AI has applications for machine learning and search problems, but consciousness is not on the radar. You can’t get there from here.

Pastor Matt: What happens when you die?

This post is from Pastor Matt’s blog.

Excerpt:

Michael Bird breaks it all down as follows:

1. Prior to Christ’s ascension, all who died descended to Sheol/Hades, which was divided into two parts, one for the wicked and one for the righteous.

2. At Christ’s ascension, he went into heaven and took with him all of the saints in the paradisal part of Sheol/Hades, while the wicked remain in Sheol/Hades, waiting for judgment.

3. Upon death new covenant believers go to be with Christ in heaven ahead of the general resurrection, while the wicked descend to Sheol/Hades waiting for judgment.

4. Eventually Sheol/Hades will be thrown into hell and all believers will share in the new heavens and new earth.

See Evangelical Theology p. 323.

I’ve featured some debates with Michael Bird before, he is a famous evangelical historian.

It’s important to understand that the Christian view of humans is that we have a material part and a non-material part. When you die, the material part goes into a tomb. The non-material part goes on to be with God, until the day when you get a new resurrection body.

Earlier, I blogged about some philosophical arguments for the existence of souls and some scientific evidence for the existence of souls, and it’s worth looking over in order to move beyond mere opinions. Like it or not, this is the way we are! Not just bodies, but souls.

Study by UCLA neuroscientist Jeffrey Schwartz falsifies materialist determinism

Here’s a summary of the research of UCLA professor Jeffrey Schwartz, authored by William Dembski.

Excerpt:

Schwartz provides a nonmaterialist interpretation of neuroscience and argues that this interpretation is more compelling than the standard materialist interpretation. He arrived at this position as a psychiatrist specializing in the treatment of obsessive-compulsive disorder (OCD). OCD sufferers recognize obsessive-compulsive thoughts and urges as separate from their intrinsic selves. For instance, after a few washings, the compulsive hand-washer realizes that his hands are clean and yet feels driven to keep washing them. It was reflection on this difference between the obvious truth (the hands are clean) and the irrational doubts (they might still be dirty) that prompted Schwartz to reassess the philosophical underpinnings of neuroscience.

From brain scans, Schwartz found that certain regions in the brain of OCD patients (the caudate nucleus in particular) exhibited abnormal patterns of activity. By itself this finding is consistent with a materialist view of mind (if, as materialism requires, the brain enables the mind, then abnormal patterns of brain activity are likely to be correlated with dysfunctional mental states). Nonetheless, having found abnormal patterns of brain activity, Schwartz then had OCD patients engage in intensive mental effort through what he called relabeling, reattributing, refocusing, and revaluing (the 4 Rs). In the case of compulsive hand-washing, this involved a patient acknowledging that his hands were in fact clean (relabeling); attributing anxieties and doubts about his hands being dirty to a misfunctioning brain (reattributing); directing his thoughts and actions away from handwashing and toward productive ends (refocusing); and, lastly, understanding at a deep level the senselessness of OCD messages (revaluing).

Schwartz documents not only that patients who undertook this therapy experienced considerable relief from OCD symptoms, but also that their brain scans indicated a lasting realignment of brain-activity patterns. Thus, without any intervention directly affecting their brains, OCD patients were able to reorganize their brains by intentionally modifying their thoughts and behaviors. The important point for Schwartz here is not simply that modified thoughts and behaviors permanently altered patterns of brain activity, but that such modifications resulted from, as he calls it, “mindful attention”-conscious and purposive thoughts or actions in which the agent adopts the stance of a detached observer.

So mind-brain interaction is not a one-way street. Everyone knows that you can alter your consciousness, beliefs, moods, sensations, etc. by changing your brain, e.g. – with drugs. But it turns out that you can also will to focus your thoughts on certain things in order to change your brain chemistry. So the causation is not just bottom-up, but also top-down.

Now mindfulness therapies – which are documented in the research papers published by Schwartz (like this one and this one and this one)- assume the existence of free will. Naturalists don’t like these scientific publications because naturalists don’t believe in free will, as the famous naturalist philosopher Alex Rosenberg explained in his debate with William Lane Craig.

This post from Uncommon Descent explains the naturalist conundrum.

Excerpt:

The issue, for Schwartz, turns on whether or not there is such a thing as free will. The assumption of free will is critical to mindfulness therapies for practical purposes.

Philosophies and religions have various opinions about ultimate free will. The therapist must ask, is my patient capable of carrying out a program that requires that he choose to focus his attention on A and not B? In practice, this turns out to be true for many patients, which makes the therapy useful. There is neuroscience evidence for brain reorganization as a result, showing that it is not merely an imagined effect.

Now, if someone wishes to claim, as many outspoken advocates of Darwinian evolution have, for example, that free will is impossible, the only thing that a mindfulness therapist can say is, go away. Either they are mistaken or the research results from mindfulness therapies are.

By the way, if you like this topic, and want a resource to show your friends, be sure and get a hold of the debate on mind vs. brain between Jeffrey M. Schwartz and Michael Shermer.
