MOSCOW (Reuters) -President Vladimir Putin on Friday warned that the West should not be allowed to develop a monopoly in the sphere of artificial intelligence (AI), and said that a much more ambitious Russian strategy for the development of AI would be approved shortly. China and the United States are leading the development of AI, which many researchers and global leaders think will transform the world and revolutionise society in a way similar to the introduction of computers in the 20th century. Moscow has ambitions to be an AI power too, but its efforts have been set back due to the war in Ukraine which prompted many talented specialists to leave Russia and triggered Western sanctions that have hindered the country's high-tech imports.
