In this episode of Investing Unscripted, Jason and Jeff are joined by longtime friend and investing educator Brian Stoffel. Brian shares his fascinating journey from a middle school writing teacher in Washington, D.C., to discovering Warren Buffett in Costa Rica, and eventually becoming a prominent writer for The Motley Fool. The trio dives deep into Brian's investing evolution—blending the extreme optimism of David Gardner with the anti-fragility of Nassim Taleb—and the painful valuation lessons learned during the 2022 bear market. They also tackle the burning question: "Will AI kill SaaS?", exploring the protective moats of high switching costs, physical world connections, and mission-critical proprietary data.
