Looking at the extent to which the long-term development of a city is becoming aligned with the requirements for its future success in an age of AI, as well as the city's recent progress, Riyadh, Dubai, and Abu Dhabi are all performing above average, in large part because of moves that the cities have made this decade to diversify their economies. Indeed, government-led AI-related initiatives in all three cities are setting an example for the world. The UAE appointed the world's first state minister for artificial intelligence. More recently, Saudi Arabia set up the Saudi Data and Artificial Intelligence Authority, which aims to boost digitization in the country's government and businesses. And all three cities are actively examining ways to adopt new technologies and to recruit leading AI research labs and innovators.
