Comparative analysis of the impact on societies of silicon technology against that of steel

Silicon is one of the most important elements in the world today, and its content in the Earths crust reaches 26%, second only to oxygen. Iron is the fourth most abundant element in the Earths crust, accounting for more than 5% of the Earths mass. It makes up most of the Earths core. Both of them play a vital role in daily human life and economic development. Silicon electronics industry, computer, composite materials, life technology, and other important pillars. Iron is used in construction, manufacturing, transportation, and so on. This article will describe the discovery of two elements and their development history. In addition, this paper analyzes the similarities and differences between the two from different aspects, comparing their impact on society. Finally, this paper gives some prospects for them. The insight gained from this paper can reinforce the understanding of the history of its exploration and their different role in social development.
