The Ethics of Artificial Intelligence
If you have not read “Moral Weight of AI” on this blog, you might want to look it over before or after reading this article as it has some overlap and will likely make both essays more easily understood when read together.
Outside of religiously based ethical systems, many philosophers will agree that sentience is the single most important factor in deciding whether or not any being has a moral status. This belief is often used to supply arguments for the ethical treatment of animals with a strong backing. As long as beings have within them a level of sentience, are conscious of their feelings and their environment, then they are placed on the moral playing field with every other sentient being in the universe.
This method of deciding moral significance has up to this point only been used in the deciding of moral status within biological beings. It does make sense that we would only apply this rule of sentience under biological settings as we have never been presented with a non biological predicament in which this rule should be tested and applied. We are very quickly approaching a time when this predicament will in fact fall before us and a decision must be made. Advances in computers are being made every day along with the ability to create newer and more capable artificial intelligence.
Currently the vast majority of the world population view computers as machines without thought, without care, existing only to carry out the functions which we have made them capable of doing. This is a perfectly acceptable and likely correct view to for the computers that we use today and will be using for quite some time. What happens, though, when we do create a computer that can learn, react to stimuli and be “conscious” of its surroundings? We have already begun this endeavor, and I doubt anyone plans to stop until one has at the very least created a machine that can match the human intellect and learning capabilities that we so enjoy.
Once a machine reaches true sentience, once it is capable of being able to view, react to, and learn from its surroundings, must we give it a moral status, or will it remain at the level of all other inorganic matter? will we treat it the same as the raw metals it was created from? If we do treat these machines as inferior beings, assuming we treat them as beings at all, what moral backing will we use to support our claims? We would have to say that one of the rules for obtaining moral status is that one must be created from organic matter. We could, of course, make this rule, and it would solve the problem of fair treatment of inorganic beings, but there does not seem to be any logical reasoning as to why one must be created of organic matter in order to obtain a moral status. Any argument stating that the material used in the creation of a being has an effect on its moral status is as ludicrous as saying that anyone that is not 98.6 degrees Fahrenheit is not actually a human and so does not have to be treated as such. The physical attributes of a being are not relevant to deciding what the being is; that is what the mental attributes decide.
An analogy that may assist in the understanding of evolution of the power of computers and their rights to moral status is this: we can take a tree to represent a computer that we use today. This tree exists and manages to carry out specific functions such as growth and reproduction. It is not at all a sentient being. It is not capable of making rational decisions to stimuli in its environment; it can react in some ways, as you can see a tree that has bent over the years to better its ability to absorb sunlight, but this was not a rational decision; it is simply how every tree of its species would react under that condition. In this way of existence it is like one of our computers. Our computer exists to do exactly what we made it to do and nothing else. It does not decide something from nothing. It follows preprogrammed steps in every situation in which it is asked to execute a task. At all stages of development of computer design there can be computers that exist in this state, just as there are and always will be plant life that can be extremely complex, yet still lack sentience.
On the other hand there will at some point in time exist a computer that reacts to the world around it in a way that is not at all similar to plant life. It will instead react in a very similar way to the sentient beings that currently exist. For this example we can take a dog as being analogous to a new artificial intelligence. A dog will react to both internal and external stimuli in order to continue its function, to reproduce itself and make whatever contribution to the ecosystem it is capable of. This dog, when presented with a stimulus that could possibly cause the loss of its life, will react in a manner which it chooses to be appropriate. This could be fleeing, attacking, or any number of other actions. This dog has a need to exist and, because it is capable of learning, it is capable of both enjoyment and suffering, physically and mentally. If this artificial intelligence is modeled after a dog and so responds to stimuli in a manner that is the same as that of a dog, it must then be considered a dog, an inorganic dog if you will, but still a dog in every mental sense.
It is also possible that we can create these complexities of artificial intelligence without giving them the ability to care about harm that may come to them or others. This brings the issue of moral status to a much higher level of complexity. In order to better understand how this being will exist, we can assume that we have reached a much higher level of bioengineering and are now capable of engineering the human mind in order to cause one to be born without the ability to care if harm comes to oneself. If this human does not care whether or not you end its life, but is entirely capable of carrying out daily functions and existing within a society, are we morally allowed to end its life? If a human today who is not bio-engineered decides rationally and logically that he does not care whether he lives or dies at this moment, is it morally acceptable to kill him? This is even more difficult than the issue of euthanasia. In some cases of euthanasia one might ask specifically to be killed. In this case one is not asking to be killed, but simply expressing an inability to care. If we are allowed to kill sentient inorganic beings because they lack the ability to care about their own wellbeing, it would make sense to be consistent and say that we are also allowed to kill an organic being which is sentient but lacks the ability to care about its wellbeing.
This issue may prove to be more complex than anything we as a race have had to deal with before. In many ways it is even more complex than the current issues of bioethics. We must come to conclusions as to how newly created sentient beings, both organic and inorganic, must be treated if we are to be able to exist with these beings among us.
