We just had our first week of our new national security class Technology, Innovation and Modern War. Given the tech-centricity of Stanford and Silicon Valley, Joe Felter, Raj Shah and I thought it was natural to design a class to examine the new military systems, operational concepts and doctrines that will emerge from 21st century technologies – Space, Cyber, AI & Machine Learning and Autonomy. Our guest speaker this class was Ash Carter the 25th Secretary of Defense.
