Lost in Translation: What the AI code debate keeps getting wrong

- AI tools are emerging to translate legacy COBOL code, but this is not the same as modernizing a platform.
- The value of IBM mainframes lies in their purpose-built architecture, not the programming language (COBOL, Java, etc.).
- Modernization involves data architecture redesign, runtime replacement, and transaction processing integrity, not just code translation.
- COBOL on IBM Z is optimized through decades of hardware-software integration, similar to iOS and iPhone.
- AI strengthens the mainframe case by accelerating code refactoring, DevOps modernization, and addressing the skills gap.
- A SaaS-only solution is unlikely to replace COBOL applications on mainframes due to on-premises dependencies and data sovereignty concerns.
- About 40% of COBOL runs on distributed platforms (Windows, Linux), requiring different modernization approaches.
- Clients like Royal Bank of Canada, NOSI, and ANZ Bank are already benefiting from AI-driven modernization tools.
