The Fourth Industrial Revolution, according to author Klaus Schwab, is defined as "a merger of technologies that is blurring the barriers between the physical, digital, and biological domains." Unlike the previous three revolutions, which were defined primarily by technological advancements, the Fourth is defined by developments in communication and networking. Changes are occurring at a dizzying pace, affecting every sector as well as every production and management system.

However, given the Fourth Industrial Revolution's rapid rate of change and wide scope, the public has expressed serious worry about jobs. Before AI, machines were passive, as they were designed to perform just the tasks that were assigned to them; however, they can now self-drive, handle accounting for businesses, inspect patients, and even compose music. In all domains, humans will now compete with artificial intelligence. Machines may readily replace people in businesses where only physical activities are required, such as driving and manufacturing. Machines, unlike humans, do not sleep, eat, or become ill. Furthermore, machines outperform humans in terms of productivity and efficiency. A man's main edge over a machine was his ability to think, but today the machine can think for itself. Would you rather hire people or machines if you were an employer?

Author Klaus Schwab uses a unique method to persuade the public: Consider horses for a moment. Horses used to have a lot of things to do back in the day. They were utilized for both transportation and agriculture. Horses, on the other hand, were mostly displaced by automobiles. What I [he] want to convey here is that humans are now in the same situation as animals. I [he] would concede that, with the coming of the Fourth, computers will be able to replace humans in all aspects of their lives, including making decisions and expressing intelligent thoughts. However, I [he] believe that, like with the previous three industrial revolutions, the Fourth will generate much more employment than it destroys ? mostly through the establishment of new industries.

In reality, there's still a lot of confusion about what the Fourth Industrial Revolution is and how it will affect our lives. Elon Musk, the CEO of Tesla, and Mark Zuckerberg, the CEO of Facebook, have stated opposing views on the matter. While Musk is wary, even calling artificial intelligence "the greatest existential threat to humanity," Zuckerberg is more upbeat, saying that AI "may be a force for good." Nonetheless, there is little question that the revolution will usher mankind into a new era.
