Can Artificial Intelligence Take the Place of Humans?

By Edited Nov 13, 2013 7 10

Movies such as War Games and Terminator have been provoked the question, can machines take the place of humans? In the past works of science fiction have proven to be predictors for future developments such as Aldous Huxley’s Brave New World (1931) in which things like the helicopter were described many years before their actual development. Of course the same works of fiction often get a lot wrong, they are fiction after all. 

Many people say that it is impossible for us to build artificial intelligence (AI) that will truly replace humans, that creativity and illogical thought processes cannot be mimicked by a computer. However, some futurist believe that the progressive incline of technology today is bringing us closer the “Singularity” or the point in time where machines and humans are inseparable. Machines, however, are taking already taking the place of humans in factories, banks and other work places. Artificial intelligence is also being used in modern warfare to reduce the risk to soldiers in tasks such as explosives disarmament and reconnaissance work. In 2010 alone 118 unmanned air attacks took place in Pakistan. And as of April 2011, there are over 5000 human-operated robots used for locating and destroying roadside bombs. These machines have save countless lives.

In factories artificial intelligence are taking the place in assembly lines. Machines take the places of human that do routine task such as put doors on cars or picking up windshields. However, most tasks machines do in factories are not too complex and are controlled by relatively simple AI programs. In 1978 it cost a law office millions of dollars to analyze 100,000 documents by 2010 it took a computer software 2 million dollars to analyze 6 million documents. There is no question that this basic AI has helped humans in their tasks.

The question remains, however, can artificial intelligence compete with humans in something requiring true human intelligence? 

The Turing Test
Since the 1950’s an annual ‘Turing test’ competition where artificial intelligences try to convince judges that they are human. [3562] The Turing test is designed to determine the answers to Turing’s questions posed in his 1950 article “Computing Machinery and Intelligence”, “Can machines think?” and, if so “… how could we tell?” In the Turing test both humans and artificial intelligence programs communicate with the judges through a computer interface and the judges try their best to decide which is human and which is not. Marshall says, “If the computer responses are indistinguishable from the human ones, the computer could be said to be thinking.” [3562] 

In his paper Turing predicted that by the year 2000 a computer would be able to, in a five-minute conversation, fool a judge at least 30% of the time. According to Marshall, “As of 2010, no computer program has met that benchmark.” [3562] However, in 2008 an entrant missed by only one vote, fooling a good amount of the judges.

Stuart Shieber, however, argues in his 1993 paper “Lessons from a Restricted Turing Test” that “the test does not measure true intelligence or human-like capabilities.” He goes on to say that “The … test that they developed rewards cheap tricks like parrying and insertion of random typing errors.” [3563] Other artificial intelligences have been able to mimic being human to a convincing degree. A good example is the CleverBot AI, which grows its database of responses and questions by recording what actual humans type to it. Despite how convincing it can be at times it is quite possible to fool the AI with a bit of human creativity.

These sorts of AIs pose the question, at what point does mimicked intelligence become actual intelligence? If AIs can mimic human intelligence well enough, will they be able to replace humans? And, most importantly, how will humans feel about artificial intelligence that can get this close to being human?

At this point the concept of “the uncanny valley” becomes an important consideration in deciding if AI can take the place of humans. The “uncanny valley” theory was originally coined by Masahiro Mori in 1970 and states that as human replicas look and act almost human, but not perfectly, humans become uncomfortable with the AI. [3564] This is because humans are very good at picking up on slight differences and if an AI is almost human but not quite, the small flaw will be very noticeable. In robotics, designers have had success by making their creations less human to account for this.

Human Robots and the Uncanny Valley
The concept of “the uncanny valley” has been important for the field of robotics and will become even more important for artificial intelligence development when considering whether an AI can replace a human. This is because in order for an AI construct to replace a human in any situation where humans must interact with the AI, the humans must be comfortable with it. A human-looking bank teller that makes people uncomfortable would not be a successful and, therefore, would not be a viable replacement.

It is not yet possible to know whether the “uncanny valley” issue can be overcome and whether an AI would be able to truly be indistinguishable from human intelligence. But with the rate of technological advance speeding up rather than slowing the occurrence of a ‘technological singularity’ cannot be ruled out. There may be a level where artificial intelligence ‘clicks’ and an “intelligence explosion” occurs. [3565] This advancement represents an ‘event horizon’ where it becomes very hard for the current levels of intelligence to understand what would come next. The ‘event horizon’ represents a point in time where the future becomes impossible to predict by anyone before that point. An “intelligence explosion” could result in an AI that is able to create even more intelligent AI furthering advancement beyond our comprehension. The human intelligence’s involvement in the process would then become unnecessary, and humans would, indeed, be replaced.

It is impossible to conclude whether or not artificial intelligence would advance to the point of human redundancy since such an occurrence lies beyond that intellectual ‘event horizon’ in our understanding. However, we can easily conclude that AI in many forms can replace humans in many tasks that do not require full human intelligence. The amount of tasks that can be carried out will increase as AI technology improves and eventually jobs that we now think humans can only perform, such as writing a novel or an essay will be able to be done by computers using formulas and databases. They may even be able to be done to such a convincing standard that humans cannot tell the difference between the work of best-selling author J.K. Rowling and best-selling author iAuthor2000. In the end the only job left for humans may be the consumption of AI labor.

Thank you for a very detailed presentation of Artificial Intelligence! Of AI in fictional movies I still regard HAL in Kubrick's 2001: A Space Odyssey (from 1968) as the best. HAL even has a flashback of his early learning when he is 'dying' while he is singing: Daisy, Daisy ...

"In the end the only job left for humans may be the consumption of AI labor." Unless we have a Skynet or a Matrix in our hands this would not necessarily be a bad thing. We already have the technological potential to replace roughly 85 - 90% of all the jobs with various technological solutions. But we cannot do that because it would shutter our credit/debt based economy. However if we did away with the current clearly unsustainable debt based economic system, adopting a resource based economic system, we could literally render work -at least all production related one- obsolete.

The point is not of course to avoid work but to have an economic system that really works in the long term and is fair for everyone. But the question remains : if we indeed reach a point when none of us will have to work -unless we volunteered- and have the robots do all the work for us, can we avoid them turning against us? And is that fear alone enough to suppress research in hard AI?

Thanks for this fascinating read. Hopefully we can keep technological advances for the good of mankind. Rated up.

Artificial Intelligence will be useful for certain kind of task or jobs. AI will learn, on how to think and solve something better - But according to our defined algorithm. It's impossible to replace our brain.

Hi ZiggyD - -

I assume you've tried Cleverbot?

I doubt we're allowed to post URLs here, but it is very easy to find.

Let me know if you give it a try.

Great article and detailed presentation of Artificial Intelligence!
I just hope that we are not totally replaceable.

Oh I thoroughly enjoyed this one.

'Number 5 is alive, number 5 is alive!' My all time fav. As for artificial intelligence in my world. my dyed black hair is as close as I will allow it to take over me *giggles like a blonde girl*

How do you come up with such great ideas?

Absolutely a great article and mindfully put together--nevertheless I will attempt to answer your question: No! Artificial intelligence will no doubt rule in certain industries not excluding war machines one day but they will always remain, in effectm machines. And machines will never know what it is like to be a machine. Anyway, two big thumbs up foryour piece--it is not only informative and thought provoking but...smart!

Very informative article. I for one believe that artificial intelligence could theoretically replace human beings in the future, but I agree with Marlando that machine self-consciousness will probably never be acheived
