Scientific and technical progress
The basis of scientific and technical progress of today is new informational technology. Thanks to up-to-date software and robots new informational technologies can make many processes much faster and transmit information more quickly.
It becomes important to learn to get new knowledge quickly and sometimes to change your qualification. IT can first lead to unemployment, but later create even more workplaces especially for highly qualified professionals. While the hardest work can be performed by robots and routine calculations by computers, in the future people with the most creative mind and numerous fresh ideas will get better career chances.
On one hand technology development gives more access to professional and cultural information and leads to new forms of individual enterprises, but on the other hand there is a danger of total control of private life unless special laws are enforced by the government. Another danger is «intellectual terrorism» when computer viruses block important programs.
There are other directions of technical and scientific progress of today. One of them is the development of new ecologically clean sources of energy using sun, gravitation, winds or rain. New kind of transports and new agricultural methods that do not harm our nature are being developed today.
Breakthroughs in science have led to creation of artificial viruses for new medicines and products, body organs for transplantation and productive soils for growing vegetables and crops.
All these innovations may have influence on our life, social relations and globally on our Earth. The influence can be very different: from psychological and health problems of children who spend too much time online to an opportunity to prevent genetic diseases for future generations. The most difficult problems the humanity faces are ecological problems: pollution of air, water and soil, exhaustion of natural resources. Renewable natural resources such as oxygen, forests, flora and fauna do not have enough time to regenerate.
Other crucial problems include wars, epidemics, and demographic problems. The only way to solve them is to work globally and in cooperation with other countries. And here the humanity should find a way to use new technologies for the common good.
