Artificial Intelligence Essay, Research Paper
Artificial intelligence is a highly debatable topic. You either believe that it may be achieved or think it can’t, and the middle is a little shady. Artificial Intelligence is the study to create a machine that can act like a human brain, including emotions, and consciousness. This speech will cover the subject of if it can ever be achieved and at what level. This would be a giant technological step. If it is ever achieved, everyday activities such as vacuuming, or laundry, would become automated. The leader in the field of AI is actually not a business, but MIT’s Artificial Intelligence Laboratory. It does more ground breaking research in the all fields of AI, including robotics and neural networks, than any other facility in the world.
First I will describe the different techniques and fields that fall under AI. The first technique that is used to create intelligent systems is the top-down approach. That is when the computer is given a written set of directions such as “IF that is red, THEN go forward” and it will go from there according to the program. This technique was widely used back in the 1950’s when AI was still a mysterious subject, but it has major flaws. To write complex programs that take in all their surroundings would take hundreds of thousands of lines of code, which no one has the time to write. The newest technique that is being used is bottom-up. That is the arrangement of data into a complex system where all information is connected, like a brain, which is why it is also referred to as a neural network. It is extremely complex and confusing at some points, so I won’t describe it here, but you don’t need to understand it to answer the question at hand.
There are also many different fields of study that fall under AI. The first field that I’ll talk about is robotics. This field has been prospering in the ’90’s. It is not so much the engineering for the robots that is causing the standstill in functionality of these machines, but the computers that control what they do, which is the problem with all forms of AI right now. There is also database processing, which works with the way that a computer sorts and retrieves information. And intelligent software agents that can tell you when to buy and sell stock among many other things. But, what this speech mainly focuses on is the theory behind all this, which has its own field.
There are four categories of viewpoints that one may have on this topic.
“A. All thinking is computation; in particular, feelings of conscious awareness
are evoked merely by the carrying out of appropriate computations.
B.Awareness is a feature of the brain’s physical action; and whereas any
physical action can be simulated computationally, computational simulation
cannot by itself evoke awareness.
C.Appropriate physical action of the brain evokes awareness, but that physical
action cannot even be properly simulated computationally.
D.Awareness cannot be explained by physical, computational, or any other
scientific terms.” Penrose 12
All that says is that it all depends if the brain functions computationally or physically (chemical reactions) and whether or not you believe that either of those can be simulated by a machine or biological creation of some kind. We will be dealing with viewpoint A and D.
If you believe in viewpoint A than you believe that computers can become “aware” of their surroundings. The word “aware” means that it can take in its whole surroundings and make judgments and actions for itself, which a giant leap from where AI is at now. It really depends on how you view how the brain functions. Research is being done by neurobiologists to unlock the secret of how the brain works. It could function by computation or chemical reactions, no one is really sure. If you think that it is all done computationally, and that humans can simulate it in a machine of some sort than you believe in A. “A is an implication of a highly operational attitude to science, where, also, the physical world is taken to operate entirely computational.” Penrose 13. There has been no evidence that supports or denies this viewpoint because the secret of how the brain works has not been solved, yet.
The viewpoint D, on the other hand totally rejects the whole idea that computers, or any machine can achieve any form of intelligence that may be mistaken for human action. The main reason for believers in this category is from the work of a German mathematician named Kurt Goedel. He was a good friend of Albert Einstein and helped him with his theory of relativity. He was more into the question of logic. His “Logic Theorem” is highly complex and impossible to explain in this speech. It pretty much says that logic is only a biological process and cannot be simulated using any form of device or algorithms. Some how he proved this using mathematics. His work is highly debatable and still only a theory and that is why the viewpoint A is still a possibility.
We will not get into the B and C viewpoints because they are extremely hazy, and not very precise. They pretty much say that you believe that the brain functions computationally and physically, but cannot be simulated by any machine. Whereas in D you believe the key to creating “awareness” in a machine will never be reached.
I, myself, believe that A, can and will be achieved. The boom of technological advances in both the area of AI and Neurobiology force me to believe in that viewpoint. My prediction is that it will be achieved by the year 2050. I’m not sure yet if it is going to be a good thing. Many jobs will be lost due to automation. Hundreds of thousands of people will replaced with machines that perform flawless and error free. And it would be cheaper to buy a machine for $5,000 that can work for 10 years, than to pay someone $40,000 a year for 10 years, that is just simple math.
AI is a very interesting field that is still in the early stages. There have only been major advances in that field in the last 10 years and I believe that it will keep on going like that. Hopefully, when I am old and can’t function for myself I will have a computer that can do it all for me.

Viewpoint is a two-level series for adults and young adults, taking learners from a high intermediate to advanced level of proficiency (CEFR: B2 - C1). The course is based on research into the Cambridge English Corpus, so it teaches English as it is really used. - Extensive corpus research ensures natural language is presented and practiced in authentic contexts. - Engaging writing tasks with explicit goals prepare learners to succeed in professional and academic writing. - Vocabulary-learning strategies encourage learner independence. - Tips to avoid common errors teach learners to use English accurately. The course is written by the same author team that produced the ground-breaking Touchstone series, a four-level series that takes students from beginner to intermediate levels (CEFR: A1 - B2).
