The 4th Industrial Revolution (4IR) involves the merging of physical, digital, and biological systems through technologies like artificial intelligence, robotics, the internet of things, and 3D printing. It builds on previous industrial revolutions driven by water/steam power, electricity, and electronics/IT. Key drivers of 4IR include digitization across value chains and products/services. While 4IR offers advantages like increased productivity and quality, it also poses economic, social, political, and organizational challenges around issues such as job losses, privacy, regulation, and skills shortages that countries must address.
