speaking balance: gold is the host, purple is the guest (3 minute bins)
Angela gently counters conventional industry fear about AI risks by arguing the real risk is not adopting Generative AI fast enough.
Hardest push from the host ▶ 9:07 Challenging modern developer thesis with COBOL legacy codeSteph questions how big banks can embrace developer-centric composable code when 40% of their infrastructure is tied up in decades-old COBOL.
Biggest teaching moment ▶ 11:45 Explaining how Gen AI handles legacy COBOL code translationAngela educates the host on how LLMs and GitHub Copilot can re-engineer legacy COBOL workflows and speed up modernization.
The host holds their own ▶ 9:07 Citing COBOL statistics from guest's prior workSteph shows deep preparation by recalling a specific statistic about COBOL usage from Angela's earlier presentation to press her on implementation challenges.
