Show Notes
In early 2026, a technical announcement from Anthropic triggered a massive market sell-off for IBM, proving that a 60-year-old programming language still dictates global financial stability. This episode explores the "load-bearing walls" of the global economy—the 220 billion lines of COBOL that power everything from ATMs to tax systems—and why its unique decimal precision makes it nearly impossible to replace. We dive into the brewing war between AI-driven "big bang" migrations and the incremental reality of maintaining the world’s most critical legacy infrastructure.
