With our entrance to 21st century, there rises the controversy of whether our future would turn to the bright one. Many people claim that 21st century would be taken into a positive way through scientific and technological advance while a great number of pessimists argue that our future is threat123d by lots of ongoing disasters. As for me, I prefer a balanced view that there will be crisis and opportunities.
On one hand, we have reasons to be optimistic. For one thing, the development of information technology will make it possible to for all the people in the world to communicate with each other easily. Take the internet as an example. A simple click on the mouse could lead you to every place and person all over the world. For another, as the medical treatment develops, it could be expected that there will be cure for such deadly diseases as cancer and AIDS and that human beings would be able to enjoy a long life expectancy. Moreover, with the ongoing mechanization, an increasing amount of dangerous and heavy-labor work would tend to be taken by the robot. In this case, man can work in more safe and comfortable conditions, as well as enjoy more leisure time.
On the other hand, it can be foreseen that there may be crises in the future. First, people will run high risk of psychological problems for dealing with computers in long-term is likely to cause the loneliness and infantile autism. Consequently the rate of suicide would experience a sharp rise. Besides, there is possibility that the robot would take over the earth, enslaving our mankind who is originally its creator. Furthermore, it is not impossible that a global nuclear war would break out. As a result, none of all creatures on the earth can escape this disaster so that from then on the civil history comes to an end.
From the discussion above, it can be concluded that we would confront both opportunities and crises. The advanced science and technology could obtain merit and drawback. So what I hope to see in the future is that we can enjoy healthier and longer life and that more and more science and technology will be employed in the peaceful way.
