Some have compared Industrie 4.0 with the Fourth Industrial Revolution. However, the latter refers to a systemic transformation that includes impact on civil society, governance structures, and human identity in addition to solely economic/manufacturing ramifications. The first industrial revolution mobilised the mechanization of production using water and steam power; the second industrial revolution then introduced mass production with the help of electric power, followed by the digital revolution and the use of electronics and IT to further automate production.[5] The term "fourth industrial revolution" has been applied to significant technological developments several times over the last 75 years, and is up for academic debate.
