Sharing a blog post on consciousness

August 29, 2018

Michele Farisco at CRB has written an interesting post for the BMC blog on medicine. He says that “whereas ethical analyses of disorders of consciousness traditionally focus on residual awareness, there may be a case to be made for the ethical relevance of the retained unawareness.”

Driverless car ethics

June 20, 2018

Pär SegerdahlSelf-driving robot cars are controlled by computer programs with huge amounts of traffic rules. But in traffic, not everything happens smoothly according to the rules. Suddenly a child runs out on the road. Two people try to help a cyclist who collapsed on the road. A motorist tries to make a U-turn on a too narrow road and is stuck, blocking the traffic.

Assuming that the robots’ programs are able to categorize traffic situations through image information from the cars’ cameras, the programs must select the appropriate driving behavior for the robot cars. Should the cars override important traffic rules by, for example, steering onto the sidewalk?

It is more complicated than that. Suppose that an adult is standing on the sidewalk. Should the adult’s life be compromised to save the child? Or to save the cyclist and the two helpful persons?

The designers of self-driving cars have a difficult task. They must program the cars’ choice of driving behavior in ethically complex situations that we call unexpected, but the engineers have to anticipate far in advance. They must already at the factory determine how the car model will behave in future “unexpected” traffic situations. Maybe ten years later. (I assume the software is not updated, but also updated software anticipates what we normally see as unexpected events.)

On a societal level, one now tries to agree on ethical guidelines for how future robot cars should behave in tragic traffic situations where it may not be possible to completely avoid injuries or fatal casualties. A commission initiated by the German Ministry for Transportation, for example, suggests that passengers of robot cars should never be sacrificed to save a larger number of lives in the traffic situation.

Who, by the way, would buy a robot car that is programmed to sacrifice one’s life? Who would choose such a driverless taxi? Yet, as drivers we may be prepared to sacrifice ourselves in unexpected traffic situations. Some researchers decided to investigate the matter. You can read about their study in ScienceDaily, or read the research article in Frontiers in Behavioral Neuroscience.

The researchers used Virtual Reality (VR) technology to expose subjects to ethically difficult traffic situations. Thereafter, they studied the subjects’ choice of traffic behavior. The researchers found that the subjects were surprisingly willing to sacrifice themselves to save others. But they also took into consideration the age of potential victims and were prepared to steer onto the sidewalk to minimize the number of traffic victims. This is contrary to norms that we hold important in society, such as the idea that age discrimination should not occur and that the lives of innocent people should be protected.

In short, humans are inclined to drive their cars politically incorrectly!

Why was the study done? As far as I understand, because the current discussion about ethical guidelines does not take into account empirical data on how living drivers are inclined to drive their cars in ethically difficult traffic situations. The robot cars will make ethical decisions that can make the owners of the cars dissatisfied with their cars; morally dissatisfied!

The researchers do not advocate that driverless cars should respond to ethically complex traffic situations as living people do. However, the discussion about driverless car ethics should take into account data on how living people are inclined to drive their cars in traffic situations where it may not be possible to avoid accidents.

Let me complement the empirical study with some philosophical reflections. What strikes me when I read about driverless car ethics is that “the unexpected” disappears as a living reality. A living driver who tries to handle a sudden traffic situation manages what very obviously is happening right now. The driverless car, on the other hand, takes decisions that tick automatically, as predetermined as any other decision, like stopping at a red light. Driverless car ethics is just additional software that the robot car is equipped with at the factory (or when updating the software).

What are the consequences?

A living driver who suddenly ends up in a difficult traffic situation is confronted – as I said – with what is happening right now. The driver may have to bear responsibility for his actions in this intense moment during the rest of his life. Even if the driver rationally sacrifices one life to save ten, the driver will bear the burden of this one death; dream about it, think about it. And if the driver makes a stupid decision that takes more lives than it saves, it may still be possible to reconcile with it, because the situation was so unexpected.

This does not apply, however, to the robot car that was programmed at the factory according to guidelines from the National Road Administration. We might want to say that the robot car was preprogrammed to sacrifice our sister’s life, when she stood innocently on the sidewalk. Had the car been driven by a living person, we would have been angry with the driver. But after some time, we might be able to start reconciling with the driver’s behavior. Because it was such an unexpected situation. And the driver is suffering from his actions.

However, if it had been a driverless car that worked perfectly according to the manufacturer’s programs and the authorities’ recommendations, then we might see it as a scandal that the car was preprogrammed to steer onto the sidewalk, where our sister stood.

One argument for driverless cars is that, by minimizing the human factor, they can reduce the number of traffic accidents. Perhaps they can. But maybe we are less accepting as to how they are programmed to save lives in ethically difficult situations. Not only are they preprogrammed so that “the unexpected” disappears as a reality. They do not bear the responsibility that living people are forced to bear, even for their rational decisions.

Well, we will probably find ways to implement and accept the use of driverless cars. But another question still concerns me. If the present moment disappears as a living reality in the ethics software of driverless cars, has it not already disappeared in the ethics that prescribes right and wrong for us living people?

Can a robot learn to speak?

May 29, 2018

Pär SegerdahlThere are self-modifying computer programs that “learn” from success and failure. Chess-playing computers, for example, become better through repeated games against humans.

Could a similar robot also learn to speak? If the robot gets the same input as a child gets when it learns to speak, should it not be possible in principle?

Notice how the question zigzags between child and machine. We say that the robot learns. We say that the child gets input. We speak of the robot as if it were a child. We speak of the child as if it were a robot. Finally, we take this linguistic zigzagging seriously as a fascinating question, perhaps even a great research task.

An AI expert and prospective father who dreamed of this great research task took the following ambitious measures. He equipped his whole house with cameras and microphones, to document all parent-child interactions during the child’s first years. Why? He wanted to know exactly what kind of linguistic input a child gets when it learns to speak. At a later stage, he might be able to give a self-modifying robot the same input and test if it also learns to speak.

How did the project turn out? The personal experience of raising the child led the AI ​​expert to question the whole project of teaching a robot to speak. How could a personal experience lead to the questioning of a seemingly serious scientific project?

Here, I could start babbling about how amiably social children are compared to cold machines. How they learn in close relationships with their parents. How they curiously and joyfully take the initiative, rather than calculatingly await input.

The problem is that such babbling on my part would make it seem as if the AI ​​expert simply was wrong about robots and children. That he did not know the facts, but now is more well-informed. It is not that simple. For the idea behind ​​the project presupposed unnoticed linguistic zigzagging. Already in asking the question, the boundaries between robots and children are blurred. Already in the question, we have half answered it!

We cannot be content with responding to the question in the headline with a simple, “No, it cannot.” We must reject the question as nonsense. Deceitful zigzagging creates the illusion that we are dealing with a serious question, worthy of scientific study.

This does not exclude, however, that computational linguistics increasingly uses self-modifying programs, and with great success. But that is another question.

Prepare for robot nonsense

February 26, 2018

Pär SegerdahlAs computers and robots take over tasks that so far only humans could carry out, such as driving a car, we are likely to experience increasingly insidious uses of language by the technology’s intellectual clergy.

The idea of ​​intelligent computers and conscious robots is for some reason terribly fascinating. We see ourselves as intelligent and conscious beings. Imagine if also robots could be intelligent and aware! In fact, we have already seen them (almost): on the movie screen. Soon we may see them in reality too!

Imagine that artifacts that we always considered dead and mechanical one day acquired the enigmatic character of life! Imagine that we created intelligent life! Do we have enough exclamation marks for such a miracle?

The idea of ​​intelligent life in supercomputers often comes with the idea of a test that can determine if a supercomputer is intelligent. It is as if I wanted to make the idea of ​​perpetual motion machines credible by talking about a perpetuum mobile test, invented by a super-smart mathematician in the 17th century. The question if something is a perpetuum mobile is determinable and therefore worth considering! Soon they may function as engines in our intelligent, robot-driven cars!

There is a famous idea of ​​an intelligence test for computers, invented by the British mathematician, Alan Turing. The test allegedly can determine whether a machine “has what we have”: intelligence. How does the test work? Roughly, it is about whether you can distinguish a computer from a human – or cannot do it.

But distinguishing a computer from a human being surely is no great matter! Oh, I forgot to mention that there is a smoke screen in the test. You neither see, hear, feel, taste nor smell anything! In principle, you send written questions into the thick smoke. Out of the smoke comes written responses. But who wrote/generated the answers? Human or computer? If you cannot distinguish the computer-generated answers from human answers – well, then you had better take protection, because an intelligent supercomputer hides behind the smoke screen!

The test is thus adapted to the computer, which cannot have intelligent facial expressions or look perplexed, and cannot groan, “Oh no, what a stupid question!” The test is adapted to an engineer’s concept of intelligent handling of written symbol sequences. The fact that the test subject is a poor human being who cannot always say who/what “generated” the written answers hides this conceptual fact.

These insidious linguistic shifts are unusually obvious in an article I encountered through a rather smart search engine. The article asks if machines can be aware. And it responds: Yes, and a new Turing test can prove it.

The article begins with celebrating our amazing consciousness as “the ineffable and enigmatic inner life of the mind.” Consciousness is then exemplified by the whirl of thought and sensation that blossoms within us when we finally meet a loved one again, hear an exquisite violin solo, or relish an incredible meal.

After this ecstatic celebration of consciousness, the concept begins to be adapted to computer engineering so that finally it is merely a concept of information processing. The authors “show” that consciousness does not require interaction with the environment. Neither does it require memories. Consciousness does not require any emotions like anger, fear or joy. It does not require attention, self-reflection, language or ability to act in the world.

What then remains of consciousness, which the authors initially made it seem so amazing to possess? The answer in the article is that consciousness has to do with “the amount of integrated information that an organism, or a machine, can generate.”

The concept of consciousness is gradually adapted to what was to be proven. Finally, it becomes a feature that unsurprisingly can characterize a computer. After we swallowed the adaptation, the idea is that we, at the Grand Finale of the article, should once again marvel, and be amazed that a machine can have this “mysterious inner life” that we have, consciousness: “Oh, what an exquisite violin solo, not to mention the snails, how lovely to meet again like this!”

The new Turing test that the authors imagine is, as far as I understand, a kind of picture recognition test: Can a computer identify the content of a picture as “a robbery”? A conscious computer should be able to identify pictorial content as well as a human being can do it. I guess the idea is that the task requires very, very much integrated information. No simple rule of thumb, man + gun + building + terrified customer = robbery, will do the trick. It has to be such an enormous amount of integrated information that the computer simply “gets it” and understands that it is a robbery (and not a five-year-old who plays with a toy gun).

Believing in the test thus assumes that we swallowed the adapted concept of consciousness and are ecstatically amazed by super-large amounts of integrated information as: “the ineffable and enigmatic inner life of the mind.”

These kinds of insidious linguistic shifts will attract us even more deeply as robotics develop. Imagine an android with facial expression and voice that can express intelligence or groan at stupid questions. Then surely, we are dealing an intelligent and conscious machine!

Or just another deceitful smoke screen; a walking, interactive movie screen?

The Nobel Prize in Economic Sciences

October 10, 2017

Pär SegerdahlIn the old days, economists received the Nobel Prize for identifying the human with an economic ideal of rationality.

Nowadays, they are awarded the Nobel Prize for pointing out that the human is not rational.

Apparently, economists know how to maximize Nobel Prize wins using an intellectual capital they never had. 🙂

Moral panic in the intellect

September 6, 2017

Pär SegerdahlMoral panic develops intellectually. It is our thoughts that are racing. Certain mental images make such a deep impression on us that we take them for Reality, for Truth, for Facts. Do not believe that the intellect is cold and objective. It can boil over with agitated thoughts.

This is evident in bioethics, where many issues are filled with anguish. Research information about cloned animals, about new techniques for editing in the genome, or about embryonic stem cell research, evoke scary images of subversive forms of research, threatening human morality. The panic requires a sensitive intellect. There, the images of the research acquire such dimensions that they no longer fit into ordinary life. The images take over the intellect as the metaphysical horizon of Truth. Commonplace remarks that could calm down the agitated intellect appear to the intellect as naive.

A science news in National Geographic occasions these musings. It is about the first attempt in the United States to edit human embryos genetically. Using so-called CRISPR-Cas9 technique, the researchers removed a mutation associated with a common inherited heart disease. After the successful editing, the embryos were destroyed. (You find the scientific article reporting the research in Nature.)

Reading such research information, you might feel anxiety; anxiety that soon takes possession of your intellect: What will they do next? Develop “better” humans who look down on us as a lower species? Can we permit science to change human nature? NO, we must immediately introduce new legislation that bans all genetic editing of human embryos!

If the intellect can boil over with such agitated thoughts, and if moral panic legislation is imprudent, then I believe that bioethics needs to develop its therapeutic skills. Some bioethical issues need to be treated as affections of the intellect. Bioethical anxiety often arises, I believe, when research communication presents science as the metaphysical horizon of truth, instead of giving science an ordinary human horizon.

It may seem as if I took a stand for science by representing critics as blinded by moral panic. That is not the case, for the other side of moral panic is megalomania. Hyped notions of great breakthroughs and miraculous cures can drive entire research fields. Mental images that worry most people stimulate other personalities. Perhaps Paolo Macchiarini was such a personality, and perhaps he was promoted by a scientific culture of insane mental expectations on research and its heroes.

We need a therapeutic bioethics that can calm down the easily agitated intellect.
