We've unleashed AI. Now we need a treaty to control it

Artificial intelligence has not yet confronted a crisis like the showdown between the USSR and the U.S. in Cuba. By and large, AI has provided us with amazingly beneficial tools. "Learning algorithms" on our digital devices extract patterns from data to influence what we buy, watch and read. On a grander scale, AI helps doctors detect and treat diseases, opens new markets and improves productivity for business, and creates data sets and models that address critical issues related to education, energy and the environment.
