[Q]: (CNN) Last Friday, a million Russian schoolchildren watched a televised address from Russian President Vladimir Putin. "Artificial intelligence is the future, not only of Russia, but of all of mankind," Putin said. "Whoever becomes the leader in this sphere will become the ruler of the world." After seeing Putin's comments, SpaceX and Tesla CEO Elon Musk tweeted that "competition for AI superiority at national level (is the) most likely cause of WW3." Though never before stated so frankly by a head of state, Putin's views on AI are increasingly shared by national security leaders in the United States, China and around the world. As I wrote in a report published by the Harvard Belfer Center for Science and International Affairs, AI research is likely to deliver a revolution in military technology on par with the invention of aircraft and nuclear weapons. In other words, Musk is correct that each country is pursuing AI superiority and that this pursuit brings new risks.Gregory C. Allen: Though Russia may not lead in AI technology, it is at the forefront of weaponizing itAs an authoritarian leader of a nation with a declining economy, Putin has every reason to employ AI to maintain power, writes Allen

"These, I think, are carrots," Obama told the Pontiff, showing him a pouch from the box, which was made from timber from the first cathedral to open in the United States, in Baltimore. The Pope gave the President two medallions -- one symbolizing the need for peace and solidarity between the two hemispheres -- and a copy of "Evangelii Gaudium," or "The Joy of the Gospel." The book was penned by the Pope and calls for a new era of evangelization and a renewed focus on the poor.The meeting is called a step toward smoothing tensions with CatholicsAbortion and Obamacare mandates on contraception are areas of disagreementOne place for common ground: the plight of immigrants and the poorPope Francis' popularity could give President Obama a small bump in the polls
