Saudi Arabia plans to invest in developing the digital infrastructure of 35 industrial cities as the country gears up for the fourth industrial revolution (4IR). The National Industrial and Logistic Program is working on this project, finance minister Mohammed Al-Jadaan said in a virtual event. Earlier this year, minister of communications and information Adullah Al-Sawaha predicted the advanced technology from the 4IR could generate around 1 trillion riyals ($267bn) for the Saudi economy in new revenue streams. The Kingdom will enjoy economic boosts from robotics, artificial intelligence, and wireless production models as it pushes for smarter cities and infrastructure, Al-Sawaha said.
