History of the Industrial Revolution

• The First Industrial Revolution used water and steam power to mechanize production. It was the first instance where production shifted from cottage industry to large production houses or factories.
• The Second industrial revolution used electric power for mass production. That is, large scale machines were brought into the picture. Huge conveyor belts rolling products one after the other, automobiles and production of electricity, defined this phase.
• The discovery of computers laid the path for the third revolution. The third phase was the most important as the machines which previously were electrically driven became electronically driven, that is, it used electronics and information technology to automate production. This came around in the middle of the 20th century.
• It is seen that each revolution took about a hundred years to establish and then give way to the next revolution.
• Now a Industrial revolution 4.0 is building on the third revolution, that is, the digital revolution that has been occurring since the middle of the last century. It is characterized by a fusion of technologies that is blurring the lines between the physical, digital and biological spheres.

Challenges

• Inequality: The revolution could yield greater inequality, particularly in its potential to disrupt labour markets. As automation substitutes for labour across the entire economy, the net displacement of workers by machines might exacerbate the gap between returns to capital and returns to labour.
• Inequality represents the greatest societal concern associated with the Fourth Industrial Revolution. The gap between those dependent on capital and labour will increase.

• Unemployment: The immediate fear of technology is job loss, particularly in informal sector. Technology is one of the main reasons why incomes have stagnated or decreased. For a majority of the population in high-income countries- the demand for highly skilled workers has increased while the demand for workers with less education and lower skills has decreased.
• Threat to Privacy: One of the greatest individual challenges posed by new information technologies is privacy. More than 30 percent of the global population uses social media platforms.
• This can also create and propagate unrealistic expectations as to what constitutes success for an individual or a group, as well as offer opportunities for extreme ideas and ideologies to spread.

• Policymaking: Current systems of public policy and decision-making evolved alongside the Second Industrial Revolution.  But the rapid changes of the fourth revolution demands broader regulations with the inclusiveness of customers, developers, and the public at large.
• Security Threat: It will also profoundly impact the nature of national and international security, affecting both the probability and the nature of the conflict. This will lead to new fears.
• New technologies such as autonomous or biological weapons become easier to use, individuals and small groups will increasingly join states in being capable of causing mass harm.
