Is war the engine of progress? Did you mean Marx's words that the class struggle is the engine of the economy? Or maybe war is the engine of progress for the United States?
War has never been good for the people, but good for the government. For his enrichment of its territory, capital. So it depends on which side you look at.
Sorg and Father Vito Cornelius are talking:
The glass is broken. Cleaning robots appear.
Chokes and suffocates.
The statement that war is the engine of progress is, of course, beautiful, but most likely does not correspond to reality. The reason for the appearance of such a thesis is probably in the visibility and rapidity of changes in a number of areas of science that occur / can occur during the war. This does not take into account the colossal losses in all areas, from the demographic situation to the economic situation of the country.
Yes, the experiments of Nazi scientists gave a lot to medicine, but the price was hardly commensurate (for either side of the conflict). In peacetime, the same research is carried out more slowly, but at much lower costs.
