Many of us think that computers are many times faster, more powerful and more capable when compared to humans simply because they can perform calculations thousands of time faster, workout logical computations without error and store memory at incredible speeds with flawless accuracy.
We can only estimate the processing power of the average human brain as there is no way to measure it quantitatively as of yet. If the theory of taking nerve volume to be proportional to processing power is true we then, may have a correct estimate of the human brain’s processing power.
* by simple calculation, we can estimate the processing power of a average brain to be about 100 million MIPS (Million computer Instructions Per Second ). In case you’re wondering how much speed that is, let us give you an idea. * 1999’s fastest PC processor chip on the market was a 700 MHz pentium that did 4200 MIPS. By simple calculation, we can see that we would need at least 24,000 of these processors in a system to match up to the total speed of the brain !!
Computers have brought a revolution in human life.
To begin with, computers took over different human activities. Now even thinking and problem-solving are being done by computer
The situation makes many of us believe that computers are likely to replace human beings in every walk of life. But every coin has two sides. However useful they may be, computers cannot replace human beings. Human life is not a mechanical affair. A pearl like tear silently rolls down the cheek at the memory of the loved one. A compliment by an elderly person restores the confidence of a depressed person. Computers have intelligence and think like human beings? Will computer be superior to us and replace us in the future? On hearing the questions, many people may think that it’s impossible that computer will be superior to human. Computer is made by us; it’s only a machine, a tool. It cannot have feelings
But a lot of facts make us surprised. Let us see what is going on in detail. A chess-playing computer can defeat the world chess champion in 1997. Nowadays, artificial intelligence has got a significant development. Computer can understand our language and accept the oral command. Computer can already do a lot of tasks and they are learning to do other new tasks one by one.
In some fields, computer works more efficient than human indeed. However, I think, we should catch the key point: computer is always doing the things that we told them how to do. We admit that if we tell computer how to do the work, it can do it and sometimes it can do better than us because computer has greater ability to deal with some special kind of problems and it will not be tired.
Computer cannot solve the new problems that it has never met The human’s development process is always raising problems and solving them again and again, these attributes cannot be possessed by the computer. , though computer can act like human, it is still a computer; it doesn’t have feelings or free will.
We have feelings, we will be happy or unhappy, we will be ashamed when we do something wrong. We have soul and we are alive. We have free will to decide what to do. Can computer have feelings? It can’t. It has no will, what it is doing is only executing the programs made by human. I don’t think a computer can ever be replaced with a human, because it doesn’t have the same physical needs that we have. But I want a computer to interface with me almost like a human. At least on the interface side to be polite like a human, to understand my human needs. I want it to serve me and understand me as a human.
However, I expect a computer to be better than a human in many ways, such as keeping track of time. I expect a computer to know what five minutes is. I expect a computer to be reliable. I expect a computer’s memory to be perfect. I expect a computer to do all the things that computers do well. Record video information – humans can’t do that – record audio information, do text-to-speech, keep an accurate and perfect record of time and what happens in time. All the things that a computer is flawless at and can do well.
I want the computer to help me. Help me augment my memory, so that when I go to the doctor and they say “What did you have for breakfast?” it could show me, “This is what you had for breakfast, I took a picture of it.” Because that’s what a computer can do for you. But I want it to understand that that’s what I need, that’s what I want. In order for the computer to understand what I need and what I want, it has to understand my emotional reactions to things, so that it can learn what it is that I need and want.
A simple touch of mother silences a crying baby. Can a computer perform these and many such other miracles? Nowadays, teaching is being done by computers. Computer-lovers claim that the can learn with the help of a computer. Computers also administer tests, declare results and award certificates. But imagine the difference between the two situations, i.e., sitting before a computer and sitting in a class room with dozens of students around us and in the presence of a teacher.
The pains and pleasures of companionship, the repudiating as well as encouraging expressions on the teachers face, the direct interaction, eye contact, spontaneous smiles and abundant sharing and understanding set this living situation a world apart from the lonely, computer-controlled suffocating room.
