In this episode of Fighting Matters, Steve Kwan is joined again by Dr. David Riedman: 17-year jiu-jitsu practitioner, MIT-trained data analyst, and PhD researcher whose dissertation focused on measuring the accuracy of large language model outputs. David is also the author of the Riedman Report, one of the most popular Substacks on risk, AI, education, and security. The conversation is broken into three parts. Part one is a broad explanation of what modern AI actually is and how it works. Part two covers the cultural and social impact of AI on public life. Part three is about how AI will affect the business of jiu-jitsu and the people who train and run gyms. Steve walks out of the conversation with a take he didn't expect: martial artists may be in a stronger position than people working in tech.
