In addition, in some areas, the significant progress of technology not only has resulted in little promotion in humanity, but also tends to, in the opposite direction, put the condition of humanity to an even worse level. As is known to all, cultural and political conflicts or even wars have never stopped; the problems of nuclear weapons and biochemical weapons, that severely threaten all the people in the world and concern a large number of countries become increasingly sophisticate; and terroristic raids are far more horrible and violent than ever before, due to which perhaps no American individuals would forget the day of Sep. 11 in 2001 when the highest two buildings on the Earth were damaged by terrorists, leaving all people in the USA with horrible feelings. No one could deny that all of these problems are to a large extent connected with technological innovations.

However, as a matter of fact, those inharmonies of humanity conditions are only within a small part in the whole world, and the overall condition of humanity has literally improved at the same pace with the development of technology. J ust consider the conditions of disabled individuals, for example, and you will find that, those who have lost one of his/her legs or even both his/her two legs are still able to lead a common individual's life without that difficulty, due to a significant development of medicine technology.
Also, because of the progress of space technology and computer science, it becomes increasingly convenient for different individuals from all over the world to communicate with each other more directly, deeply and thoughtfully, which to some extent, avoids some mutual cultural misunderstanding and culture conflicts, even wars. Besides, with the improvement of scientific research and medicine, people all over the world are able to strike together with severe illnesses such as SARS and Bird Flu, both of which are new widespread infectious diseases in the first several years of the 20st century. All the above shows considerably better condition of humanity resulted from the development of technology.
