China’s population is shrinking and aging fast—a shift that could reshape its military future. In a new episode of Policy Minded, RAND’s Mark Cozad explores this challenge facing Beijing and what it could mean for global security. If China manages to overcome these demographic obstacles and achieve its modernization goals, it will gain confidence. And as Cozad says, “A People’s Liberation Army that is more confident and more willing to assert itself could become a much bigger problem for the United States.”

Generative AI is quickly spreading through America's public schools. But pre-kindergarten teachers have been slower to adopt these tools than other educators. Recent RAND survey data show that only 29 percent of pre-K teachers used AI last school year. That's compared with 42 percent of elementary teachers, 64 percent of middle school teachers, and 69 percent of high school teachers. Why the big gap? And how can policymakers ensure AI helps meet teachers’ professional needs and students’ developmental goals?
