In this episode of Disbelief to Doubt we turn back the clock to 2018 and sit down with former IARPA Director Dr. Jason Matheny who served as IARPA director from 2015 through 2018. In part one of this two-part interview we discuss a wide range of topics, including Jason's early career in science, how being a "force multiplier" drew him to IARPA, lessons learned from IARPA's first 10 years of tackling "IARPA hard" problems, the role of the U.S. as a leader in artificial intelligence (AI) research and development and much more.
