The most outstanding contribution of scientific and technological development is the productivity revolution again and again. Mechanized production has replaced most human labor, which has doubled the production speed and efficiency. Now the emergence of artificial intelligence and 3D printing technology has pushed productivity to a new height. Humans can produce better and faster without any effort. In the future, robots may replace all human physical strength.
In addition to productivity, technology has also brought about earth-shaking changes in transportation and information dissemination. Cars, high-speed trains, ships and planes make our trip convenient and fast. Places that used to be far away can now be reached in a few days or even hours. Moreover, this speed is still increasing, and the birth of hypersonic vehicles will enable us to reach anywhere on the earth within 1 hour. In the foreseeable future, ordinary people can also travel in space by spaceship.
With advanced communication equipment, as long as we have a small mobile phone, we can meet and chat with our relatives and friends no matter where we are. You can know the world events without leaving home! This reminds me of an ancient poem "God never shuts one door but he opens another". It can be said that the development of science and technology makes our world smaller and smaller.
Secondly, scientific and technological progress has increased the output of various crops and solved the problem of feeding more than 7 billion people around the world. Nowadays, even in desolate Africa, it is rare to hear of people starving to death. Transgenic technology, advanced irrigation equipment and advanced management technology make intensive land production possible. The output has doubled. People no longer have to worry about eating.
Second, shortcomings.
However, while people are intoxicated with the enjoyment brought by science and technology, they are also faced with a series of adverse consequences brought about by the development of science and technology, such as industrial pollution, global warming, shortage of fresh water resources, continuous extinction of various animals and plants, destruction of biological chain, and proliferation of nuclear weapons. I think it is self-evident how harmful environmental pollution is.
Various infectious diseases emerge one after another, and no cure can be found in a short time. Just waiting to die. The rising temperature caused the poles to slowly melt, and the rising sea level flooded some land. Some people will lose their homes and even die in floods. At present, the nuclear weapons of all countries in the world add up to enough to destroy the whole earth several times. Moreover, the struggle between countries makes nuclear weapons uncontrollable. In order to get the trump card of nuclear weapons, some powerful countries are secretly developing them. North Korea, for example, would rather eat grass in poverty than abandon its nuclear program. In this case, who
Can we promise not to use nuclear weapons? The future artificial intelligence robot is a great threat if it is not controlled. As we all know, intelligent robots are smarter than humans. How can we make all kinds of abilities and wisdom higher than our own and always obey our command? Is this possible?
What if one day this person is not a person, a ghost or something like a ghost, and instead plays with humans? Can it live in harmony with us? Once out of control, how will mankind end up? Of course, the bitter fruit brought by the development of science and technology does not stop there. If these problems are not properly controlled, then science and technology will lead mankind to catastrophe! This is by no means alarmist.

How to develop science and technology healthily?
The healthy development of science and technology must be guaranteed from three aspects: economic conditions, social environment and national policies. It should be guaranteed from the aspects of policies, regulations, organization and institutionalization, including establishing a mechanism to ensure the social operation of R&D activities, establishing a decision-making body to ensure the development of science and technology, and establishing a science and technology system adapted to the market economy.
As long as we can always keep in mind that the ultimate goal of the development of "science and technology" is to "bring happiness to mankind to the greatest extent", we can operate healthily and continuously in society. With this general direction of social development, once the development of certain technologies harms or may harm the overall happiness of society, the development and use of such technologies must be resolutely banned. On the contrary, if such technology is beneficial or more conducive to the overall happiness of society, we will continue to support it.
