This year’s Davos World Economic Forum (WEF) summit was held under the theme — The Fourth Industrial Revolution. According to the WEF, the first industrial revolution used water and steam power to mechanise production. The second used electric power to create mass production. The third revolution used electronics and information technology to automate production. Now a fourth industrial revolution is the digital revolution that has been occurring since the middle of the last century and has been characterised by the integration of the physical, digital, and biological spheres.
