Please list several examples of scientific and technological inventions affecting human life and talk about what help they have provided to mankind.

The development speed of science and technology far exceeds our imagination, which is not only a result of the improvement of productivity, but also creates conditions for further improvement of productivity. Because of this, Comrade Xiaoping will assert that science and technology are the primary productive forces. However, not everyone cheers for the rapid development of science and technology. On the contrary, quite a few people insist that science and technology are a double-edged sword, which can not only benefit mankind, but also bring disaster to mankind.

First, banks now use high-tech equipment such as computers to help with their work, which not only improves work efficiency, reduces the work intensity of staff, but also facilitates customers. However, the widespread use of computers has brought another problem: some lawless elements use various high-tech technologies to destroy computer networks, steal confidential bank documents, infringe on depositors' interests and obtain illegal benefits. What is particularly disturbing is that with the progress of science and technology, there are more and more so-called high-tech crimes, which makes people feel that "the road is one foot higher and the magic is ten feet higher". For another example, Einstein's theory of relativity plays a very important role in the peaceful use of atomic energy and the solution of human energy crisis. However, the deadly atomic bomb was also produced under the guidance of this theory, which brought greater crisis to mankind. Similar phenomena provide evidence for those who support the view that technology is a double-edged sword. Therefore, when scientists successfully bred "cloned sheep" at the end of last century, some people were not cheering, but worried. Admittedly, there are reasons for this concern, but persisting in this concern is not conducive to improving our scientific and technological level. For example, cloning technology can be used in many aspects, such as organ transplantation, to alleviate the pain of many patients. However, for fear of abuse, many countries prohibit or restrict the development of cloning technology. Will this become a new kind of "give up eating because of choking"? Is science and technology the primary productive force or a double-edged sword?

It is not easy to answer these questions clearly. First of all, we need to know what science and technology are. To this question, the textbook's answer is: Science is the knowledge system for human beings to know nature, and it is the spiritual power for human beings to conquer and transform nature. Technology is the labor means and technical method in the production process, and it is the materialized form of people's scientific knowledge, labor skills and production experience.

The strange phenomenon that "science and technology is a double-edged sword" will lead some people to oppose the development of science and technology. A simple example can be used to illustrate this point: in many cases, the use of a technology requires paying the patent transfer fee to the technology owner. You can't use it if you don't pay it, let alone the service. In a competitive society where the law of the jungle prevails, won't the strong who master technology pose a threat to the weak who don't?

What is science and technology if it is not a double-edged sword?
