The human brain and the computer in the past few decades we have seen how computers are becoming more and more advance, challenging the abilities of the human brain. We have seen computers doing complex assignments like launching a rocket or analysis from outer space. But the human brain is responsible for thought, feelings, creativity, and other qualities that make us humans. So the brain has to be more complex and more complete than any computer. Besides if the brain created the computer, the computer cannot be better than the brain.
Many say the computer will be more powerful than the human brain. There are many differences between the human brain and the computer, for example, the capacity to learn new things. The most advance computer can never learn the way a human does. While we might be able to install new information onto a computer, it can never learn new material by itself.
Also computers are limited to what they "learn", depending on the memory left or space in the hard disk, not like the human brain which is constantly learning everyday. Computers can neither make judgments on what they are "learning" or disagree with the new material. Computers must accept into their memory what it's being programmed into them. Everything that is found in a computer is based on what the human brain has acquired though experience.
In addition, emotions can be only transmitted by the human brain and cannot be programmed into a computer. One of the reasons is there are too many emotions to be described and they can be such a mixture of feelings that it would be hard to put it into one category. Furthermore, the computer wouldn't have the ability to know to what situation it should apply certain emotion. And different emotions can be applied to the same situation; it all depends on the experiences in our past. Emotions are personal and are different for every person, and it would have to be differen for every computer. Another difference between the human brain and the computer is, the creativity of the human brain.
For instance humans can create art, act in plays, or write stories and songs but computers can only help us in these activities not come up with them. While computers can help us solve math problems and find answers to certain questions it can never think of new solutions until they have been programmed into them. Furthermore computers cannot create new games or produce anything they desire like humans. In fact, the human brain is the one who comes up with new ideas or theories not taught before.
But in a computer, everything that is there has being thought out by the human brain. The computer also lacks the sensory organs like the eyes, nose ears, tongue and the sense of touch. The eye is very important to the human brain it can absorb millions of details in an instance; where as, the computer does not have a sense of sight. The computer cannot achieve the sense of smell like the brain can be already registered with so many scents and aromas.
A computer cannot decide what it wants to listening or play, like the human brain is able to. Taste and touch is something a computer will probably never acquired. In other words, the brain can receive and distinguish information though the sensory organs. Every year computers are becoming more complex, but can never be equal to the capacity of the human brain.
The human brain is able to acquired new knowledge and skills by thought or through experience. The human brain has the power to create things and come up with new answers while the computer cannot. The human brain is capable of experiencing emotions and the ability of the five senses. In conclusion, computers will never be able to take the place of humans because without our brains there wouldn't be any computers.
