Modern technology has a more extensive social role, and people put forward ideas like "technology builds a country". Marx "sees science first as a powerful lever of history, and as a revolutionary force in the highest sense". It is of course a decisive role to be "a powerful lever of history". Lenin also gave a high evaluation of the social role of science and technology, "it is also the cause of all other progress, the cause of progress." So, what role does technology play in social life and what value it embodies? This article puts forward some of my own views on this and gives examples.
